Re: Polaroid TDA-03211C - Strange Spots on Screen

Most likely moisture as dick_barton suggests. Don't apply heat to the spots directly on the Screen. The best way would be to open up the Panel and take a peek. If it is moisture I would wipe it with...

Re: LG 50uh5500 no picture

Your TV has bad Backlights. You would need to open up the Panel and carefully remove the very fragile glass screen. Replace ALL the Backlights strips though not all would be defective but it is good...

Re: campomatic tv secret service menu

I have found that if Backlights strips go bad and you have to open the Panel, then replace ALL the Backlight strips with new strips. Repairing strips by replacing just the bad LED WILL fail again as...

Re: Backlight and Sound But No Video on Vizio P502UI-B1E

Your Post Header says Backlight and sound but no video. Then inside the Post you say you hear audio from my source, but no video and no backlight. Are your Backlights working? If YES then your...

Re: LG 60UH8507 Backlight turns off after few seconds

I would suggest you change ALL the backlight strips, instead of the single bad strip. This will guarantee not having to open her up again for along time. Remember to turn down the Backlight setting...

Re: Samsung UN40H5203AF LED backlight blinking

The only long term solution is to replace the LED Backlights. Not just the bad strip but ALL the strips to prevent having to open up the Panel multiple times.

Re: LG50PK350 C802 Cap choice?

Your fault now lies with the Z-sus Bd. Perhaps when the Z-sus Bd. took out the 0.047uF cap.

Re: Vizio E32-C1 No Standy Voltage

OK. With all Bds connected and screwed down in place, when you plug in the TV to the ac you do not see a stand-by led on. Now when you press the Power button on the TV or the Remote, the TV does not...

Re: Help with Canton Ergo As 2 subwoofer

Pity you didn't show the underside of the Bd from where the burnt resistor was. I would star with a 10k 2W wire wound resistor and try it. Progressively try lower resistors until it turns on, as long...

Re: Toshiba 32L1350UD

There is no BL-ON/OFF and PWM signals from the Main Bd. The BGA Chip could need some heating to fix this issue.

Re: Panasonic P60ST60 7 lights, then 8 lights, then 10

I think the new SC Bd will fix your problem.

Re: Samsung PN51F5300AF does not turn on

Good job. Luckily you were able to find replacements for all the boards and even get a working Main Bd from the Seller. Good JOB.

Re: Sony soundbar SA-CT260H no power

The only way to really know is to replace these two components if you can locate them and give it a try. There may be a flash memory on the Main Bd to reload the software.
