Screen and sound cuts out at times.


I would check the power board capacitors. Many people are losing the electrolytic caps on these boards. It is possible yours are failing only when they heat up.

Tv has sound but no picture


I had similar problem with my Polaroid 42 inch. The screen would be fine for 10 minutes or so then go black. I found a work around that solved my problem and maybe you can to. What I did was remove the back panel of the TV. Make sure it is unplugged first. You should be able to see the electical board. Somewhere on the board may be a switch that says "Burn" or something with "Burn" in it. I set the switch to the "Burn" setting and the TV has worked fine ever since. Good Luck.

The common issue with polariod is there power supplies, Your going to have to fork out something for the repair if you not willing to buy a new TV here, A new board in this would be $175 labor another $80 or $90 tops. So you getting into $250 fast. This is why I say to all my askers NEXT TIME buy a extended warranty. This will need a new power board sorry to break it to you and its the common issue I am seeing on fixya.com from my premium chat customers. Please do be considerate as this information was free to leave postive feedback and maybe a ranting or two.. for all those expert involved in your case today.

The screen gets black in some minutes of working, the sound continues


My LG LCD HD TV was doing the same thing. I would turn it on and within about 10 minutes the screen would go black.

After much research and troubleshooting I ended up having to send it out for servicing.

Before you do that, try these steps
  1. Is your TV plugged in to a power strip, splitter, UPS or other power sharing device? If so, plug it directly in to a wall outlet. If the TV is getting low power it can cause issues
  2. Does your TV have other video sources plugged in to it? (Example, Digital Cable, DVD Player,XBox 360) If so, try a different source and see if the problem still happens. If the problem does away, it could be the source. If the problem still happens then its still a problem :-)
Hope this helps!

Screen goes black, still have audio


I first changed the 220uf capacitor with no luck. I flipped the BURN switch to on and the set has been working great for a week now. Daughter left it on for about 20 hours overnight with no problem. Anybody have an idea what those 4 tiny switches are for? I have heard these type of switches called "dip switches". They are tiny white switches in a yellow block on the lower left side of the upper circuit board. The top one was labled 40", the next one down was labled 46", the 3rd one was 4 letters "EW" something I think, and then the bottom one was labled "BURN".

Black screen with sound


The TV lasted a little over a year & I'm glad I didn't get a warranty. A repairman estimate was $512 but he is still waiting for a control module replacement for other customers. They purchased the exteneded warranty but have been waiting over 6 months for parts that are still not in. I trusted the Polaroid name, my mistake to trust a name.
