The backlight inverter board may have gone out, or the power supply for the inverter may have gone out. If it is two years old, you should look at the power supply first for bad capacitors.

My Polaroid flat screen tv started smoking and the picture went off, but there was still sound. What happened and can it be fixed? This tv is only 2 years old.


It can be repaired, however, the cost is probably going to be in the area of $200.00 or so. Unfortunately these were not reliable sets. I have repaired way to many of them to recommend repairing it.

42 inch flat screen shows black screen with sound only no picture


That sounds like the backlight system or its powersupply has failed. If you can see an ghost like image when close and at an angle near the dge (depends on the light) then this confirms the backlight being the problem.

Repair cost should be about $100. You should be able to get this fixed under warrenty if you have any. If not get repair estimates before doing anything. It should be worth fixing but it never hurts to know if it is getting close to what a new replacment tv is worth.

No picture, good audio. Replaced motherboard...


I think I may finally have the answer for the "black screen of death" for the 42" Polaroid LCD televisions. I was having the same issue with the screen going black after a couple minutes of being on. I would shut it down then turn it back on and it would work again for 5-10 minutes. On the "power board" which is the board on top, there is a little red light that turns on when the screen would go black. above that there are 4 little switches, the lower on says BURN. I simply switched that over and the television has been working for 2 days for 8 hours + each day. Hope this help. Let me know
