Re: I have a polaroid 42 inch flat screen and the screen...
Make sure all the connections are correct, a "blue" screen indicates no-signal, black indicates some type of signal is getting to the tv. good luck Julio [email protected]

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.
No! The power supply board is working, you have sound but no picture. the problem appears to be in the high voltage module, if the inverter transformer has failed the screen would go dark. this will require a tech to troubleshoot the problem.
Ur LCD inverter board is dead.This LCD inverter board,help to get the LCD screen,to have backlight go throught the Tuner board to get the cable or free air tv signal to get a picture.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish LCD inverter board for the replacement.It a long board in shape.
Most likely when you disassembled the unit to replace the capacitors you unplugged the screens data cable. When you replugged this you probably didn't get it plugged in correctly or bent some pins.
well if the light stays blue , that means its still on ...what you may need to do is go to your menue and select the setup selection and then go to tuning band.....i belive it will be on page 32 of you manual, under customising the setup settings....in order for the tv to start working it needs to be able to scan for channels.....if you are useing a cable company like comcast or direct tv...depending on how you pluged it into the tv ,(like using the input 1 or 2 , s-vidio, cable , ectra,)...you need to push the input button thats on the lower right side of your remote and select the propper input area as to how you hooked up your cable box
