Have you checked diodes, resistors, transistors? If they work fine check fuses and voltages. They usually tell you by the connector. If you aren't used to using a multimeter with a live tv get someone else to check it for you.

The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.

You must have some electronic experience when you replaced the bad capacitors.
Best thing to do is find a Service Manual for your TV on the internet. It will really help you in a big way to diagnose the source of the problem. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20.
Another thing you might want to look at is the power supply for the screen. Most manufactures call it a Backlight Inverter Board. The TV maybe trying to power up the screen and failed. Then, when into protection mode. The Service Manual should define the red light blinking code for you.

I hope I shed some light on the subject for you.

SOURCE: LG 50inch Plasma received loud sound then went black

I had the same problem with my LG 50 inch TV that I bought from Best Buy in Nov 2006. Fortunately I had the service plan. They had to replace the power supply board as 9 capacitors popped, so the TV would turn on them pop and go black and turn itself off. The TV has been a pain. I have the built in DVR and that has failed twice. I have had 3 repairs through best buy. One more time they owe me a new TV when they come out.

Can a cooling fan be fiited to my 50inch philips plasma tv


yes to your ? i asume you have had the back off of this tv...there are 6-7 modules inside. the power supply is where you need to focus some attention. and yes plasma sets do overheat.try to find a way to attach 2 120mm fans to the heatsinks. then try to find a 12 volt source with a volt meter. attach the fans to that source and you are good to go. be carefull not to short or overload the power supply. or you will be spending 3-4 hundo for a new 1... good luck..
