Question about BenQ PDP-46W1 46 in. HD-Ready Plasma Television

1 Answer

No picture my power button shows green, however I get no picture what so ever. Should I send it to a repairman or will it probably be something too expensive? I can't afford to dump a lot more money into this unit.

Re: no picture

Could be the panel or a logic board, you must take pane voltage measurements and unhook the cables one at a time to see if the voltages come back up

My panasonic th-42pwd8uk tv wont power on. When I press power it clicks to turn on then clicks again and the screen never shows up. No red lights no blinking lights just a solid green light.

Check the capacitors and replace the power components. It is an easy fix if handy with soldering electronics. Tv Repairman may charge less than $100.00 bucks to fix it !
Good luck

Our picture will only show reds and greens, no other colors.

Go to your On Screen Menu to picture settings and reset and choose "reset picture" mode. This will bring you back to factory defaults. If this doesn't work shut off wait 10 sec. and turn on the TV. If still no luck call your best friend who is a TV repairman, you probably have a damaged blue drive.

It shows bars of different colors and then powers off

The television needs a main board and or a panel. This will probably be too expensive to repair. You can see if Sharp will make and exception for you and let you send digital pictures of the problem in.

No power. Possible power supply issue.

If the repairman guarantees that the problem is the power supply and will agree not to charge you if that is not the problem, then by all means go for it. Most TVs it is what is called the Power supply Unit, or PSU, and the part alone costs well over $100...

Power button is green - no blinks / no picture / no sound

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

No picture, but power is on...

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
