Hi my name is Eric,

I can help you with your issue,

 

So is the Tv open with the back removed

 

 

Please tell me your technical ability,

1 I can solder and check voltages and want to know what board/part is bad so I can fix it myself

2 I am pretty good at figuring things out, but do not want to open the Tv up

3 I just know how to turn on my TV

This way, I can help you without getting to technical unless needed.

here is what it sounds like it might be:

Either the power supply has an issue , or you have a panel

A repairman will usually just ordered the boards and you will spend over $300 probably around $350

 

It could be just a few bad capacitors on the power supply, if you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on top.

 

look at the photo I am uploading to see what a bulging cap looks like

With the back removed you will see a few circuit boards the upper one (ac cord runs to it through a small board) is the power supply, it has alot of capacitors on it (cylindrical standing straight up soldered in and marked on the sides with the positive/negative sides and MF and Volts values)

Philips and Samsung use 2200Mfd or 3300mfd at 35Volts rating capacitors, they cost about $1-$2 each
usually I replace two of them (or all the bulged on top ones) .

The power board and back unscrew with a torx bit and screwdriver size 10 and 15 , if you do not know how to desolder and resolder then do not attempt this as you may damage the TV more than fix it.

We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.

dont see any with obvious bulge, resistance checks ok. other possibility?
Expert:  Eric replied 7 years ago.

If there are no lights at all, no power light most likely the power supply board.

Voltage checks would be nice

I usually take the board out and look for bad solder connections on the bottom too

Thanks
