That'll be the inverter board. It might be the 6632L-0490A made by LG Philips. If it is, you'll find the 2 capacitors have leaked and a bit has blown out of the chip. The inverter board is hidden behind the main board on the 505 model.

Found that video 1 and video 2 switching does not work. The switching IC was HOT!. Then found a third video input works but no sound. Hooked -up sound output of DVD player to amplified loudspkr and it works, I hate to throw away a 2 year-old plasma TV when TV and cable still works.
Thanks for the offer anyway.

no, the tv has a setting that auto changes the screen ratio. you can turn the auto screen ratio off in the settings section. Once you have turned it off put ratio to 16:9 and it will solve the problem.

Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.

Sound but no picture


This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.

Connect TV to a different input device. If it works it is a problem with the set top box or cable. Look for any loose contacts in the RC Cable or RF Cable. Show a torch light on the screen when the program is on and if you can see the picture, the backlight is not getting on. This may need attention by a qualified service technician.
