Check its main power supply regulator board, for its voltage outputs, and input. Contact any service technician. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair.Whether you suffer fatal electrical shock.Instead, contact the nearest service center.

No it stays in place , its a cover that will get pushed in with the optical cable. Do remove the cap from the cable if thats still on.

Why not? Remove it. Do not fear. It will not harm you by anyway.

Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.

Yes. you can remote it.

The Inverter needs replacement. You can get the replacement Inverter from www.tvrepairworld.com

no sound either? Also is this set connected to a cable or satellite box for signal?

are you sure that your hdmi cables are good? the first thing i would do is get one that you know is good and plug it in to your tv and to something else, and make sure both are on, and see if it works, if that don't work then you prob have a problem with your source.

the main board is the usual cause of those symptoms. You should be able to get a replacement main board by contacting the guys at www.tvcircuitboards.com

Yes , it can be a short on the board that will ask the SMPS unit to protect the power so as to switch off. So even with a multi-meter check you will be able to trace the short on the board, the drivers or any capacitor that is cutting off the power which must solve the issue.

The screen size is also called the aspect of the TV. look in your menu for aspect ratio.

Possible failure in the inverter section as the power seems to trip off as a protect function. It will be best to isolate the inverter section and see if the power build up , if so there can be a short in the inverter section possibly the drivers.Check the secondary voltages from the power supply without load and then with load, the processor seems to work as the stand by is triggered and then it shut off on protection.Check by isolation.

have you found a solution
