Check the Y-sustain drive board. If it is faulty /shorted, this kind of fault can occur. Short circuit protection circuit inside the TV energizes, and switches it OFF, to prevent further damages, is now going on. Will be best to contact any service technician. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts. Check the site in 'Mosaic' view. It will make search easy.

I think you have a defective power board. the pop sound in coming from the board and giving you a low output voltage. do it yourself price about two hundred for parts.

Sorry to lay some bad news on you.........

It sounds like your set has had defective silk screening during the manufacturing process.

The lines in a plasma set are laid out using a silk screen process, the defects (if any) are burned out by laser, then the surface is sealed to protect the lines with a vacuum coating process. Your set sounds like it had a manufacturing defect that quality control somehow missed...it happens!

The good news is that since your set is brand new, you should be able to exchange it. Don't delay!

I have the LG Plasma model 50PA550. the TV turns on for a few seconds, then turns off by its self. The more I continue to turn on the TV the quicker it turns back off (until it just doesnt click on anymore...


If you're an electronics DIY...I had the same problem, TV turns on then immediately turns off. Fixed it with an 89 cent capacitor. TV is an LG 50PA5500, two and a half years old. Suddenly stopped working...would switch it on and it would immediately turn off. Sometimes if I left it unplugged for a while and plugged it back in, then it would click at intervals of 1 & 5 seconds repeatedly.

Inspection of the main power board showed C802, a black rectangular film capacitor at the top of the board between the transformer and heatsksink was bulging at the sides. Found the part, 0.022uF 1.25KVDC, on DigiKey (p/n 495-1360-ND) for $0.89 + ~$3 shipping (much cheaper & more reliable than eBay!). Replaced, TV working like new again.

42 inch LG Plasma TV - Lost picture


This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.
