40 inch polaroid lcd tv


This is a common problem with Polaroid sets. I would check the power supply/inverter board for any capacitors with bulging tops. The typical ones that cause this problem are 10uf 450V caps.

I am attempting to attach a Samsung Sound Bar to my 42 inch LCD 1080P Polaroid Television. I can not seem to get sound from the Television connected to the Sound Bar. Thoughts?


Connect the audio out RCA jacks (white and red) on the TV to the white and red RCA input jacks on the sound bar for analog stereo sound or connect the black digital audio output jack (typically optical) on the TV rear panel to the sound bar's optical digital audio input jack for surround sound. Use an optical cable. There may be some user settings on the TV for audio.

When my polaroid flat screen tv is turned on humming


Check to see that you're not in SAP mode, (Separate Audio Program) in the audio portion of your menu. Could also be filtering via a bad cap or two in the audio circuit the the hum is a 60 cycle hum because of it. If you have a cap analyzer you could check those also.
Hope this helps!

TV won't turn on


I have fixed many polaroids, the problems is most of the parts are contained in one self contained control box. it sounds like your power board is not funtioning. contact polaroid and let them know about your problem and see if you can get a new control panel. the contol panel only has one connection and 3 screws to replace. hope this helps.
