Hello polkjhydvrg,
was that sarcasm? or are you fishing to spam???

grayfox

for customer whom I cannot find a reset hour timer function and cannot access the service menu, I usually just recommend they take out the lamp and leave the TV unplugged overnight. Then reinstall the lamp and close the lamp door and plug the set back on, this should have the timer running from zero...

, learning alot! hope I can help!

Hello Dave, This sounds like a text book ballast issue :geek: (you can read multiple post for malfunctioning ballasts in Samsungs here on this forum) :x I would try replacing that, if you did the colorwheel work yourself, exchanging the ballast will be a walk in the park, see below for a sample guid...

grayfox

I was unable to find your DMD board...

not even Samsung parts has it!

grayfox

true sorry, multi-posting , got confused! but my gamer friend, I sincerely think that there is a bigger change the lamp you installed is faulty, even if your ballast is weak, is it a Philips lamp???

grayfox

true, and the DMD board will come attached to the complete light engine, (DMD, light tunnel, projector lens, etc). Yes if you take a look at the last image you posted that one, along with the fact all inputs are affected, points directly to the DMD board (includes the digital micro mirrors, hence th...

grayfox

yes and no, all inputs are plugged directly into an input board that is usually called the analog video board, so even though the signal does not need reach the DV board it HAS to pass through an input board that can be faulty. I am starting to lean to the DMD board for some reason, (its so hard to ...

grayfox

You are correct on all accounts, however I would not start replacing the power supply as a first since, if it is malfunctioning in a way it can damage the colorwheel, it has already done so, following that logic I would try the colorwheel first. Also I forgot to mention the overall Analog input boar...

grayfox

hmmmm it can be, but I am doubtful, have you tried toying around with your TV settings? the refresh speed might be affecting... brightness... I would play around a bit before, because if anything is wrong I am almost sure it can be the ballast.

grayfox

hello again! well you beat me to the punch and tried out analog vx digital signals which would have been my next move... since analog inputs go through a digital video board before the dmd and digital signals go straight to the dmd that rules out the DV board. now if you have had issues with the col...

grayfox

will do!

grayfox

Because of the color and the distortion you describe in the pictures, I think a safer bet would be to replace the colorwheel first as a cheaper way to trouble shoot, I am ruling out DV board since Analog and HDMI inputs seem to have same distortion...
hope this helps!

grayfox

then this might be an internal / service menu option, have you ever replaced the lamp before?

If you have not, does your manual say where you can reset the lamp hour timer?

grayfox

on samsungs there should be a counter but it is on the service menu which is hard to access... do you happen to have your owners manual?

grayfox

this can be damage to the Digital video board but more likely a DMD board issue... does this affect the integrated TV menus?

grayfox

Yes the image will get dimmer as the TV lamp ages, regular use consumes the mercury vapor required for the ignition of the lamp. hhmm no noises? i still think you should run a visual inspection of the colorwheel and while you are at it, dust the interior (this fixes the issue about 30% of the time w...

grayfox

Hello, I think your lamp should be fine since you are getting a picture and the lamp only shines white, no colors. ;) I would open up the TV and check to see if the colorwheel is damaged, because this sounds exactly like when one shatters, are you getting any weird sounds? :shock: I do not know of a...

grayfox

hello, as a fellow black ops fan, I know how you re-create this problem. ;) How long ago did you replace the lamp and how many times have you replaced it? :?: my first thought is that the Ballast (part that controls and provides power to the lamp) is weak and when asked to power up a bright white it...

grayfox

Good to hear, :D we have a word for those -at home improvised quick fix its! (being in sandiego we all speak spanglish) its called "chikanada" its a step around "McGivering it" :lol: Thank you I will keep you in mind and add you as a friends here on the forum, If you have any future trouble with any...

grayfox

hmmm maybe the jumper, take a look at the link below (scroll down to the "jumper" part) and read the explanation, if this doesn't help please advise!

grayfox

at this point I have to figure there was some damage to the DMD board. Let me see if any of my tech friends can help out..

grayfox

you wouldnt imagine how many times a simple dusting fixes a clients TV

good luck, you know where to go to for help!

grayfox

You are a trooper! I like the way you think, you should come work for us!

Good luck, I am sure you will do just fine

grayfox

whoa, let me help you look around, the best bet is to go for the new ports, they don't change (same # of pins) so you can pretty much solder any HDMI ports!

grayfox

Hello Jeff,
this could be one of three, colorwheel, Digital video board, or at the worst the DMDboard/light engine, you can start by opening up and dusting the inside of the TV, and taking a visual inspection of the colorwheel, make sure it is spinning freely.

grayfox

I would order any mitsubishi input board (the cheapest ;) ) on a site like www.discount-merchant.com that has HDMI ports and recycle them! :lol: , just make sure whom even is doing the work knows what he is doing, :geek: we don not want to damage you OG board, :shock: Oh and good luck on the claim!!...

grayfox

Hello again, if the distortion was as it seems in the picture to only affect the integrated TV menu, I have to speculate this can be the DMD board or maybe even just the digital video board if this was on an analog input..

grayfox

Both will work on your TV since they both cover the 132 Watt range, but I would recommend using the 132-150

since it allows for higher wattage.

grayfox

Hello! If you were getting no other distortion or discoloration before it went out, I would consider replacing the lamp since it has been a year, it is not "new" truth is no aftermarket lamp lasts as as long as the original, the second trouble shooting step would be to replace the lamps ballast sinc...

grayfox

it can also be done by taking out the lamp and leaving the TV unplugged for 24 hrs. just to make sure the timer and the TV is reset.

grayfox

BYO stop following me!

grayfox

Your wife did it!

grayfox

I think BYO supports my idea Winder, any updates?

grayfox

GOOD TO HEAR!!!

yes those green bars could have been the DMD board, but if the part was new or refurbished it was probably settling in somehow!

Anyways you know where to go if it starts acting up!

grayfox

ok! keep us posted on the fix

grayfox

discount-merchant.com has a good inventory at cheap prices, but try taking out the lamp and then unplugging your TV for 24 hrs... that might help...
I do not fully understand why but it seems to work for some of my clients!

grayfox

yes it is the same lamp, even if the specs are labeled differently they perform just alike.

grayfox

Hello!
following the logical train of consumable parts to be changed in a RPTV, yes a Ballast probably needs replacing... anything else you can share to help diagnose?

grayfox

you can unplug the TV and take the lamp out for more than 24hrs... If that does not work I would order a ballast!
Also try buying a used remote on eBay, I always find them there for my clients...
Hope this helps!

grayfox

you need the part number off the actual ballast itself! (some dissasembly required!)

grayfox

hmm... ok so does it happen mostly once the tv is warm? that is, once never right after ignition?

grayfox

Hello,
This looks like it can be a colorwheel issue, are you getting the same distortion on all inputs? if so, when it happens does it affect the on screen menu? (TV internal menu not Dish, Cable, etc)....

grayfox

Hello Bud!
My name is Gray, I am a TV repair Tech. Welcome!

grayfox

Hello,
It should be right above/behind the lamp... If not it could only be an extraction fan at any end of the TV...

hope this helps!

grayfox

hello, I do not think any company will warranty a Lamp for a year without purchasing an extended warranty, Discount-Merchant has a 6 month with an option for 1 to 2 yrs extended warranty, so do other companies. You should know it is normal if your original lamp went out after 4 yrs, that the ballast...

grayfox

Hello, I do not think you touching the lamp could have damaged it ;) , (unless you were working in a relatively high static environment, like the carpet) It happens yet it is very unlikely and if there was damage it would be irreversible. :cry: . I am a Discount-Merchant fan, I know they will ship y...

stiday if this leads to spam I will need to ask the admin to delete your account...

grayfox

Wow, you are in fact a fan of Toshiba! for some reason their DLP TVs are the only ones that use Direct Current (D/C as opposed to A/C) lamps...
I LOVE their laptops, I used to be way into DELL but my girlfriend brought home a Toshiba Satellite and I jumped ship!

grayfox

It is no problem jWatts!

That is very nice of you

a cold one is always welcome, as a SDSU alumni i'd like to extend you the same kindness, any time you are anywhere near Sunny San Diego, I know where the best Bars and Dinners are
