37" Polaroid HD LCD black display but appears to be "on"

37" HD LCD Polaroid TV - At first it would not turn off unless unplugged, then when powered up and turned "on" (blue light) there was a flickering screen, then all went black but the tv appeared to be "on" with the blue "on" light. We still cannot turn off the tv without unplugging it, and now it will not display at all, even though the blue "on" light is lit.

We have a Polaroid 37" HD tv that has a loud


You have weak capacitors in the power supply and the signal board. I have not repaired this particular unit, but have experienced this with other Polaroid TVs. You will need a TV tech to replace those capacitors. It is a very time consuming task and requires patience and much care to remove the capacitors. Tell a tech that they must be very careful when they remove a cap in the signal board, as they can peel off a pcb trace. In most cases they replace the signal board, but the capacitors can be replaced! Thanks for asking and show a few hands of support!

Polaroid 26inch lcd tvred standby light on but power wont turn on. I've unplugged the tv, changed the batteries in the remote. The tv stays with the red standby light only.


You need to open it up and checking the voltages in the power supply sections, you should have 5v (for logic circuits), 12v for sound, 24v for backlight inverter circuits. Look for bad caps with bulging tops in power supply also.
