Hello and thank you for the question.

How long have you had the set for and when did the problem occur?

Was it after a storm, surge or power outage?

Also, does the light blink 4 times, then go out?

Or is it 4 blinks, pause, 4 blinks, pause, etc.?
Customer: replied 10 months ago.

set is 6 years old no problems ever


no power surge


4 blinks pause 4 blinks pause

Expert:  Aric replied 10 months ago.
Thank you for the reply.

Has the set ever shut down on it's own previously, or taXXXXX XXXXXer to turn on?

Also, when you power the set on right now, does the screen attempt to light up even for a second?

Do you have a meter and the ability to measure live voltages?
Customer: replied 10 months ago.

the set has never taXXXXX XXXXXer to turn on and hasn't shut down on it's own.


It doesn't attempt to light up the screen at all.


I don't have a meter reader, but do know what one is and could get one.

Thanks for the reply.


It's up to you, what I need to know now is the following:


Do you have experience measuring live voltages and are you looking to repair this yourself?


Or are you looking for a repair estimate and service locator?
Customer: replied 10 months ago.

repair estimate and service locator. I do know a service location but it's


about 1 1/2 hours from my house--- big honking tv you know the drill.


I worked in a electronic store for 4 years, then sold passive electronics


commercially. That being said, it's been a while.

Expert:  Aric replied 10 months ago.

Well here's the thing, what we would need to do on a DIY level, is use a meter and test ALL of the voltages coming from the supply, to ensure Vs is around 175 volts DC, and that Va is around 70. Also, check all power supply board capacitors, to make sure that none are bulged or leaking.

A shop would typically charge between $200-$250 for that type of repair.



If the supply caps and voltages look good, then we'd need to check the Sustain board heat sinks, to make sure that ALL are warm, and none are screaming hot or ice cold. In the even that they are, then we'd replace both Sustain boards (there is one on each side of the Plasma panel).



Average cost for this repair is verging on $450 parts and labor.



If the Sustain boards are working, and the supply voltages are good, then we'd move to replacing all of the Scan and driver boards- cost here is $250 parts and labor.



The last possible culprit is a failing Plasma panel, and this is the only part of the TV that is non-repairable as the panel costs more than the TV itself.



Unfortunately there is not a one shot diagnosis for this problem, and either of the culprits mentioned above can cause the problems you're having.
