Question about Polaroid 4226TLMB 42 in. LCD TV
I have a Polariod Digital Picture frame model XSA-10169S. Starting a few days ago, the LCD screen goes dark during powerup and stays that way. The Polaroid Logo is bright as normal for a few seconds and then it goes to the darkest possible mode. I know its not dead because I can see the pictures and menu screens but it is too faint to be of any use. Unless you put your eyeball right up to the screen, it appears completely black.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

So, I couldn't get the tuner to work (tried everything). Eventually I realised the cheapest solution would be to buy a digital set top box, and use this as the tuner instead of relying on the one built-in to the TV. Works fine.
But yes, I won't be buying another Panasonic in a hurry.

I had a TLX-4240B 42" Polaroid LCD TV and the screen would go black after about 10 minutes. There was still sound. I removed the two covers exposing the circuit boards behind the TV. I powered up the TV and waited for the screen to go black (I was going to start trying to pinpoint where the issue was with my trusting meter) then noticed a red light would come on when the screen would go black. there were 4 mini switches right above the red light. I switched the one that said burn and the TV has been working great since. good luck and let me know!

To add to this solution above - I had the capacitor replacement and there was still an issue. Turns out the solder connection to the lamps themselves was very very poor causing an electrical arc (the scratching noises people are hearing) - then the inverter shuts the lamps down as it should. Fix lights!

SOURCE: I have a polaroid 32
There are 2 capacitors located on a circuit board that have gone bad. They are located inside the TV. It is very easy to take apart and inexpensive to fix. If you know how to soldier you can do it or sent it away like I did to fix mine. On the back of the TV there are 3 screws holding on the cover. One is big in the middle and the other 2 are small on the ends. Remove them and slide the cover off. Remove the screws holding the metal cover and take it off.
The top circuit board has the blown capacitors. Located on the left top 2 small round tubes located at E17 & E18. Unplug the 3 or 4 connections carefully on the board and remove the 6 screw holding it in place. Take out the board and replace with new capacitors. I sent mine to JD Electronics in Poland Me. and he fixed it. I put it back in and it is fine now. I ordered the capacitors from DigiKey.com Part # 493-2069-ND. They were $1.09 a piece.
Hope this helps...........
