Hello! yes this can be one of 2 things, - a fan that is malfunctioning and needs to be replaced before it causes a component to overheat - or the colorwheel, which will start to give you hue/tint/color distortion. The easiest way to diagnose is to open up the back shell and clip the sensor (the one ...

grayfox

we will wait to see what happens! good luck!

grayfox

Hello again!
sorry to hear that!

I actually made some research on your tv and could not find -what I think- would be a logical explanation; maybe that part is the Achilles heel of that model!
let me know if the eBay seller exchanged it for you!

grayfox

Hello, this is definitely a colorwheel issue, after listening to the youtube audio. Sometimes it is going to act up and some times it wont, but given the color distortion I am 90% sure you need to replace your colorwheel!

grayfox

yeah I would bite the bullet on a lamp and if it fixes it perfect! if not then at least its not the cost of a lightengine/DMD board ($300!!!).

glad to help!

grayfox

if after trying out all the inputs, you still get this distortion, this seems like a DMD board issue...

grayfox

if you just replaced the colorwheel for a new one you might have to remove the jumper piece as seen on the link below

if the picture is perfect this is most likely a colorwheel issue!

Dejavu Hello! sorry to hear that :( this is a simple fix however, It can be one of 3 consumable parts in your tv... 1- the most obvious and common is the Lamp, it will pop and maybe buzz when it does. have you removed it? 2- the colorwheel, when it shatters or malfunctions can give you a whirling or...

I contacted the moderator, He is a good friend... RE-POST!!!

grayfox

lol I know the feeling!

and yes it is overwhelming at first, then you find it is too easy...

keep us posted!

grayfox

good! yes please keep us posted, many people come on the forum and find a solution without even posting thanks to contributors!

good luck!!!

I have seen some sort of service computers, kind of like the ones used to diagnose car problems, but only certified technicians can purchase these and they are very expensive, not worth the trouble unless you plan on fixing a bunch of Samsung DLPs! I would try the colorwheel, the only problem seems ...

grayfox

Yes and no, maybe! the colorwheel situation is a funny one. it can give you color distortion, but it does not have to. The sound of a dying colorwheel i would describe as a whirling, grinding, ball bearing ring... if you open up your tv and put a trip in the switch (its usually blue and is there so ...

grayfox

yes in the short run , bad in the long run, since it can allow an incorrect voltage to the lamp resulting in a shorter lifespan of the lamp, it is better to replace the whole board

grayfox

where did the original question go?

grayfox

I am sure anybody with a light engine / DMD board issue has been down this road...

Good news is that you can buy the complete DMD/lightengine since they are usually sold together. And you will know almost all boards in your TV are working fine!

grayfox

I have no idea if a temp sensor can cause this, I do not think it can...
The power supply could be sending the wrong voltage, then again the most probable reason; maybe some components on the actual ballast are causing them to blowout. Have you tried replacing the complete ballast???

grayfox

Hello!
and YES!!! this is most likely a colorwheel about to hit the wall at top speed! or maybe just a fan... but if it is shutting down your TV or taking a while to sync up and boot, then I would replace the colorwheel because the bearing could be about to give out.
hope this helps

grayfox

Hello! before you spend time on diagnostics! :P I would recommend first taking off the back shell and taking a look into the colorwheel :roll: due to the fact that those pieces of glass are most likely pieces of the colorwheel! this is VERY common in Samsung DLPs. :| look at the guide below :mrgreen...

grayfox

Hello,
yes this sounds like a textbook lamp replacement issue, see below
http://www.discount-merchant.com/Search ... =1&cat=200
but the clicking sound might indicate a ballast issue, I would try the lamp first!
hope this helps

grayfox

hello,
so you tried both digital and analog inputs? (like an hdmi).
Since this does not affect the menu I think the DMD is fine and you might be experiencing an issue with the digital video board.

Hope this helps!

grayfox

Hello, have you contacted the tech? this sounds alot like a DMD issue...
Why was the original DMD board replaced?

grayfox

hello! right of the bat I have to advice you might have to change your ballast :( this has nothing to do with the "hourglass effect" I just believe it to be weak because this is a recurring issue with Samsungs and a weak ballast can only power a weak or spent lamp, and when you put in a new one it i...

grayfox

Hello, if a tech checked your tv it could be one of 2 8-) -either he thinks it is the DMD and it is malfunctioning in a way it gives you the lamp error code :( -or its just a lamp issue and he wanted to plant a heavy sale :evil: any symptoms you can describe? the sure fire way to know would be to in...

grayfox

so the lamp and ballast are both 8 months old. hm.

do you know if you got a genuine Samsung ballast?

there must be a reason this ballast went bad right off the bat and I want to discard the power supply... did your tech tell you why he replaced the ballast?

grayfox

Hello again! OK now the darkening seems clear. This seems to be a light obstruction of some kind. Most of the time it is the alignment of the lamp or its path towards down the tunnel... My suggestion, after all the cleaning and inspection you just made would be to remove the lamp and make sure it is...

grayfox

Hello, I really doubt the housing can cause any of the symptoms you describe :( Also Osram or Philips Lamps should not be going out so soon! I think the problem since the begining was with a defect in the ballast I have seen this before, I would replace the ballast, you can find then online for unde...

grayfox

, well the picture you posted I assume is the cloudy fog on a backlit blank screen?

I know im asking again but if I had an actual image in the back I could get an idea of whats happening...

grayfox

Eddie,
wow there is a whole bunch of website dedicated to Panasonic dvd problems...

the most thorough one I found is called "Panasonic dvd players - the history behind the problem" !!!

grayfox

Yup this is basically as easy as it is posted plug and play notebook HDD is what Sony installs from factory!

grayfox

Hello,
the easiest part to replace would be the ballast which is the board that powers up the lamp, I do not think a power supply can be at fault but I would not eliminate it as a possibility...

grayfox

I have an idea, but please feel free to educate me more :roll: , I am basing myself on logic :P The PS3 is a perfect Blu-ray player, my only concern is the lens. When playing regular PS3 games the disc spins and it "reads" the disc for "loading purposes. Then once loaded into the system we play! Whe...

grayfox

yes but the endless supply of apps!!! not even android has as much...

grayfox

Hello,
you probably can if it is a Universal remote, but it is better to get a OEM part (original remote) like

grayfox

Hello Jim,
did you ever get a part number for that power supply on the monitor??

grayfox

wow, great fix JJG!!!

be careful when resetting the lamp hour timer if you are using different specs on the ballast! you do not want to short out your lamp!

other than that cheers on a job well done!

grayfox

Hello everybody, sorry guys but I think this Topic is to greet new comers! please do not post questions about trouble shooting!

grayfox

broken screen on LCDs are really expensive to replace, I would imagine impossible without a receipt and the only one I have found I have had to pick them up since they mostly do not ship them because of how fragile they are..

grayfox

No sorry, there is only a Samsung guide, but they are mostly the same steps

grayfox

most likely a ballast issue, if the ballast doesnt ignite the lamp, it is going to give you the lamp error light

hope this helps

grayfox

Hello,
Yes all of the light engines and optical blocks in DM come with a DMD board, actually it is hard to find a bare DMD board online anywhere!!!
hope this helps!

grayfox

hello!
When a lamp goes bad, it is usually shattered, burnt in the middle glass bubble (on the inside filament) or fogged in any spot on that same bubble or the front glass face.

A good lamp should be crystal clear!

Hope this helps

grayfox

yes thanks! definitely try to document it! It can help another fellow techie!
Happy Holiday!

grayfox

Hello, This can be a lot of things :shock: , do not worry all of them easily repaired :D Questions: :P what part of the screen is the dot in? Does it look like a digital clear crisp round dot or is it fuzzy and inconsistent? does it show on all inputs? and more importantly do you have a screenshot?!...

grayfox

yes unplug it for at least an hour, then since the part numbers match im sure this is the part you need, but run a quick visual inspection of it just in case

grayfox

hhmmmm I think there's either some obstruction in the light tunnel, or the lamp light is not pointed correctly...
I would dust it once more thoroughly to see if it clears it, maybe use a can of air like the keyboard type, just make sure your tv is unplugged

grayfox

Well to be honest (as a tech) its cheaper to do it yourself, it is not that hard, look at the guide below...
