Re: sound works, picture is very dark

You have to be specific when asking a question please. as you dont mention its a flodable LCD screen TV as I had to look it up. your problem is in the backlite circuit. if your a tech, you should have no problem finding this fault but could be a little trick if your not as your going to need to know how a back light circuit works, the parts in the circuit and know how to use a multimeter. Good Luck

13" emerson tv has terrible audio. it used to

Bad grounds are common and need to be resoldered. Next you may already have a few bad capacitors that will need replaced. If you can locate the audio output IC, you should check in this area for bad capacitors and bad grounds. 99% of the time a bad ground and bad capacitors will offer you goofy problems in a TV. So take heed and inspect, resolder and replace those capacitors. Thanks for asking and show a few hands of support!

Sounds like it could be a bad inverter for the screen lamp. If it is a bad inverter and the tv is still under warranty you should send it back for a replacement or repair. If the tv is not under warranty and you have some experience working on electronic devices you could probably find a replacement inverter online and replace the bad one.

Tried turning on my Sony and no picture no sound, just a black screen

Sony is known for having problems with the picture tube. Sometimes it will blink on and off. also bad connections on the main board. A CRT restorer will sometimes help with picture tube problems but this must be done by a tech that has one.

32 Toshiba TV no picture / bad pciture

Hello Suzid, It looks to me like you have a possible power supply issue (poor brightness on screen, shrinking of the picture, and initially no picture) This problem may put you in danger of electrical shock, so I would suggest that you not try to repair this set yourself. I would suggest that you take the television to a television repair shop.The power supply issue could be a low power or a high power supply problem.

Dark Picture

...the answer is correct...the power inverter for the cathode backlight is a complete failure with these Polaroid models.  Polaroid should really step up and fix a known problem.  Mine was purchased as a gift and not opened until the worthless 3 month warranty expired.  Didn't work out of the box!!!! I will never purchase a Polaroid product again since they obviously don't care about the consumer and sell a product that they know was defective.

Is there no buttons on the set to adjust the volume??? I've never seen a tv that didnt have at least under a door somewhere. Do you have an owners manual? You can get a universal remote to get this to work Good Luck!
