I have a 42inch Philips...
I have a 42inch Philips plasma tv, 3 to 4 years old that has just developed reddish diagonal lines across any white screen. It's almost like it's in the background but I have pretty much isolated it to the tv. Any Ideas what I have wrong? Randy

Hello friend, Thank you for posting your question on Just Answer! I will be happy to help you with this problem, And possibly help you save on these Labor charges today, So please don't Accept my answer unless you are satisfied,

 

would like for you to measure all high voltages,, You may simply need to change the Y and Z boards

(Please click on high lighted words) this is my sample may not be the same model but doesn't matter the technology is the same.

Would like for you to take your meter and place it on DC voltage the positive end on every connector that says a voltage and the negative wire to the panel this is the best ground. Turn on and see if the voltage is present at the VS, VA, V-scan, According to the Label. Also if a voltage is missing remove each board from the power supply to make sure they are not holding down the voltage If you don't find one that's trying to climb, or shows close to what it should be, another method is to locate a short circuit place meter on ohms or beep test follow same procedure no voltage should be shorted to ground. And this is the problem. You can unplug each board one at a time, Starting with the Y-SUS then the Z-SUS.

Friend this is a very common problem with plasma. Within the power supply the capacitors

Start to fail and the way you can tell is to check them visually for swelling or expanding of the top.

It will be easy to see the bad caps will not be as flat on the top as the good ones

 

Normally the parts for this unit is a kit Y-SUSTAIN AND Z-SUSTAIN BOARD, this is what most manufacturers would want you to do, purchase them. But go to high lighted words and go through all the voltage checks to find the bad part, here is also a chart that should help a lot, also this is a picture that will help with identity.

Well Good luck friend, and if my efforts are appreciated, feedback and a bonus will be appreciated

 

Thanks Simplified click here

I am not sure this really answers my question, to add one more part to this , it seems like previously bright spaces on the screen do not go away for minutes, like the picture is not erasing previous screens along with the reddish areas of the screen. any ideas with this info?

I would measure these voltages,,, your VS or VA can be off,, Also sounds like a burn in problem,, but the reddish issue is a bad Yand Z board,, If you adjust these voltages up or down you can solve this problem,,
