Hi my tla-01911c tv powers on and displays the polaroid logo on the screen for about 30 secounds then shuts down as if there is a power overload or something. any ideas? thanks

Audio amp may be blown. A cable may be bad.
What are you connected to?

This is a common symptom of a power supply failure on the TLA-01911c. The board has parts called capacitors that filter the output power and when they go bad the power supply does not power up right. The unit can either have no power, just a flashing power light, just a white screen or it could take a long time to show a picture. Here is a link to a repair guide that shows what to replace on the power supply board to repair the unit.

I hope this helps you get your TV bad up and running,

Hello,

A white or gray screen usually means the power supply board is not functioning correctly. Below is a repair guide showing what to look for on your power supply board. Open the back of your TV and look at the power supply board as shown in the repair guide. If the capacitors are bulging on the top then they have failed and replacing them should get the board and TV back up and running. This is a very easy repair if you can do a little soldering.

polaroid LCD has white screen and no sound

Hello,

The white screen and nothing else usually indicates a failure of the filter capacitors in the power supply board. When these capacitors go out the voltages are not correct so the TV can not power up right. You can rebuild the power board by replacing the bad capacitors and this should bring the TV back to life. Here is a link to a repair guide for this power supply board.

You probably have a bad inverter PCB. It is a skinny board by itself over on the left side of the back of the panel.

I had the same problem. I replaced 14 capacitors on the Power supply board. I used Panasonic FC series. You could look for swollen capacitors or ones that are oozing. For sure replace these. My set had capacitors that are known to cause problems so I replaced all of them even though I saw no swelling of oozing. Be sure you label all connections carefully when you disassemble.

Press the power button on it. That usually helps. In case you're wondering it's the bottom button on the right-hand side (The TV's left.)
