Hello, A dim screen usually is due to a lamp nearing the end of its life span. If the lamp is 2-3 years old chances are a new lamp will bring the screen back to its original brightness. A weak ballast usually is able to power an old lamp since most of the mercury gas has been consumed. If a new lamp...

Hello,

I would definitely have the ballast looked at. I'm not sure how old the TV is but it's possible the ballast no longer puts out the voltage the lamp needs to work properly. That or the power supply might not be powering the ballast correctly.

ChubbsTech

Hello, Sorry for the delayed response. I wish I had better news but it sounds like your problem can be either the main board or even the dmd board. Main board would be the cheaper repair. The following link will take you to a pic of a main board so you can see what it looks like. Its very hard to de...

Hi there,

If you heard a pop it's gonna be time to replace your bulb. You might find broken glass which is pretty normal. Make sure you replace with either Osram or Philips a sgenerics are not good bulbs at all.

Hello, It's possibe your ballast is no longer putting out the voltage the lamp needs to ignite or remain lit. This is the component that power the lamp. These components are consumable so eventually they will need replacing. Keep in mind a weak ballast can power a old lamp but not a new one thats be...

Hello,

I am assuming your bulb is under warranty still. If that indeed is the case I would try an exchange. If you were to have the same situation then the ballast would be the part to replace.

Hello, First what I would rcommend is making sure the bulb you purchased was a OEM. Philips or Osram would be the only lamps that we would recommend. Anything else would be a generic compatible lamp. If you do have a OEM bulb the ballast would more likely be the problem. This is the component that p...

Has the ballast been replaced before ? If not that could be your problem. The ballast will eventually stop putting out the voltage the lamp needs to ignite. It's a consumable part so eventually it will need replacing. Sometimes a weak ballast will make a rapid clicking sound or an electrical buzzing...

ChubbsTech

Hello, I would try he ballast first since it is pretty much the second most common part to file due to the fact that it's a consumable part that with time loses the capability to put out the necessary voltage these lamps need. Keep i mind that the ballast first needs to put out a higher voltage to i...

ChubbsTech

Bikey, Just keep in mind that your old lamp can also cause your TV to shut down. Obviously if you do have a new lamp in there and the TV shuts down with the new lamp then there's a problem elsewhere. I just want you to be aware that these TV's are designed to start shutting down when the lamps lifes...

Thanks for providing us with an update !

ChubbsTech

Hello, Unless your fans are not working they should for the most part be OK. As far as the temp sensor it will most likely be on top of the lamp housing. Just to be sure since you are wanting to replace your ballast I am assuming you have a new lamp in the TV. If not it is definitely recommended to ...

ChubbsTech

Hello CobraSnake7, Your ballast could also be the problem if it hasn't been replaced before. This is what powers the lamp and since this is a consumable part it will need to be replaced eventually. Most DLP owners by the time they have had their TV for 9 years have already replaced the ballast. I wo...

ChubbsTech

Thank you for sharing that with us.

Appleads, Could it possibly be the ballast ? I know they sometimes make a humming or buzzing type sound so i'm wondering if maybe that could be the issue. Honestly I have never heard of a DVI board making this noise. Please let us know if you were able to get to the bottom of it. i will try to do a ...

ChubbsTech

Hello, Just to be sure the lamp that you now have in there is it a new bulb ? Reason I ask is these bulbs can look good but if they are simply out of mercury gas they won't ignite anymore. Another possibility could be the ballast which is what powers the bulb. These components with time will lose th...

ChubbsTech

Hello, It sounds like both your color wheel and ballast are starting t act up. The ballast powers the lamp. The reason why your old bulb doesn't shut off will be because an old bulb requires less power from the ballast to ignite and remain lit. The new bulb requires more power due to all the mercury...

ChubbsTech

Hello, Try a hard reset this sometimes helps. Just follow the steps below. If this does not help the temperature sensor could be needing replacement. Just unplug the TV and take out the lamp. 2) While the TV is unplugged, press and hold down the power button in the TV for 2 minutes. 3) Leave the TV ...

ChubbsTech

Hello, I am assuming that the ballast has never been replaced before. The ballast is the component that powers the lamp. This is usually the 2nd most common part to fail after the lamp. With time the ballast stops putting out the voltage the lamp needs to ignite and remain lit. It first needs to put...

Hello,

Can you confirm when was the last time the lamp was replaced ?

ChubbsTech

Hello, The link below will take you to a page where you will see a picture of the driver. The website you will be on is a very good source for manuals schematics and troubleshooting information. I think it will be very informative and helpful to you. I believe finding out whether the actual led's ar...

ChubbsTech

Hello, Can you confirm if the recently installed lamps were OEM or generic ? Mitsubishi originally comes with an Osram lamp although Philips is an even better lamp. You want to atleast have one of these in your TV because generic lamps don't have a very long lifespan. Please advise and we will get r...

ChubbsTech

Hello,

Your Tv being led gets it's light source from it's led's, are you able to tell that these are on ? Or is the screen completely dark ? If the Led's are not turning on the driver more likely needs replacing. This is what powers the led's.

Hello,

From what I was able to find out the actual audio amplifier is on the main board and not the signal board.

Hello,

If you try to go to your menu when you see no picture, do you see the menu ?

ChubbsTech

Hello, The ballast usually goes out before the color wheel although not always. You mention a sound similar to brakes dragging on a car. This could be the bearings in the color wheel starting to go bad and not allowing the wheel to spin freely and at the speed it's supposed to. The system will detec...

ChubbsTech

Hello, Some of these Tv's have an auxiliary power supply. I tried researching and trying to determine if yours does but wasn't able to find out. Check to see if you see one. Usually it will be smaller than the main power supply. Remember also these have a ballast which is what powers the lamp. So ma...

ChubbsTech

Hello, It is a little weird that now after installing the DVI board that you would suddenly get these clicks which I assume are coming from the ballast. I believe it's possible that the DVI board itself could have issues and might need a replacement. Let us know of your findings after reinstalling t...

ChubbsTech

Hello, mike56dlp, Ten years is a long time for a DLP to continuously work without issues. The bulb obviously will eventually need replacing and if you haven't replaced it before I would start there since for the most part it's usually always the first part to need replacing. There are a couple other...

Hello,

Please provide the TV model # to better diagnose the issue. Thanks !

ChubbsTech

Hello, If your ballast has never been replaced more likely that's gonna be your problem. The thing is that with time the ballast no longer puts out the voltage the lamp needs to ignite and or to remain lit. Just cause there is no flicker doesn't mean the ballast is good. The ballast actually is the ...

Welcome Cativo !

ChubbsTech

Hello,

You mentioned that you get no picture but that the bulb is bright. Are you saying that the bulb is always on but you still have no picture or does the bulb turn on only sometimes ?

ChubbsTech

The bulb was on yet no picture correct ? Now when you did get a picture did the bulb get brighter ?

ChubbsTech

If this buzzing sound is like an electrical type sound the problem is gonna more likely be the ballast. This is what powers the bulb. You mentioned that the bulb was on, while the lamp was on was there a picture ?

Hello,

Your DLP chip should have the part # on it.

An audio dropout occurs when the audio portion of your program stops and then restarts a second later. This phenomenon can be caused any of the following issues: Faulty firmware A weak signal HDMI handshake sync problems A faulty HDMI cable Faulty HDMI ports or circuitry. Regards,

Hello,

Discount merchant is a trusted site. I actually recommend a lot of people to them since they seem to have a lot of hard to find parts. Always at a good price.

ChubbsTech

Hello, The cause more likely was a bad connection between the ballast and the lamp housing. It's possible that they didn't connect fully. The gap in the plug leads to an arch of about 20,000 volts which causes the melting of connectors. I recommend replacing the entire ballast as you might not be ab...

ChubbsTech

Hello,

Sounds like this could still be a convergence problem. I understand you replaced the coolant a few years back but the lifespan on this is not that long. This technology unfortunately is pretty much obsolete. You might be better off looking into another TV.

Regards,

ChubbsTech

Hello,

There should be a part # on the chip itself. You want to be sure to replace with the exact same part #. If the bulb has never been replaced before I would recommend to replace it since it will more likely go out at any time now. This of course judging from the TV life span.

Regards,

ChubbsTech

Hello, Sorry for the long delay in responding. The DMD is a possibility although the main board can also be at fault. It's hard to know exactly which one but obviously if one does not solve the issue then the other should. For parts I recommend going to www.discount-merchant.com. They still have a l...

ChubbsTech

Hello,

If you use a different input or say you only have a antenna connected does it do the same thing ? Trying to determine if maybe it could be a faulty digital video board. Please advise.

Hello, This particular model was part of a national recall. Apparently due to bad capacitors. The link below will give you information. I am not sure if you would still be able to file a claim but I believe it's worth looking into. Samsung is supposed to fix the issue free of charge. http://www.reca...

ChubbsTech

Hello, Sounds like the boards you are looking into replacing will more likely solve your issues. Although to me it sounds like the color wheel might also need replacing due to the green sparkle with vertical lines that you mention. For parts I recommend you contact Discount Merchant. Their website i...

ChubbsTech

Hello, Please check to see if you feel any vibration by placing your hand on top of the TV as it powers up. If you do there is a good chance the color wheel is starting to act up. Usually it's lamp failing first then the ballast and the color wheel usually soon after. The thing is these are consumab...

Hello,

Try the converter box if possible and please let us know if that helped any.

Hello,

Definitely sounds like the DLP chip needs replacing. I would recommend calling discount merchant as they carry these parts at good prices. To ensure you get the correct chip a part # is the best way to go. Your part # would be on the your original chip.
