This solution is for a Polaroid flm-373B 37 inch LCD TV. I noticed your TV is the flm-3734B. Hopefully this solution will work for you too.

I suspect you may have 2 capacitors in your control module that need to be replaced. When these caps start to go bad it will often show up as a problem with the sound. However, when they get really bad they can prevent the TV from turning on. Please see the link below, posted by stiv0. It gives detailed instructions on how to replace these caps and to tell if they're getting bad. If you follow these instructions you can take the back off the TV and check out the caps. If the tops of the caps are bulging they need to be replaced. Just be sure to replace them with the correct value (1000uf) and use caps that are rated at a higher voltage than the originals. I replace the 10v caps in my flm 373B with 25V caps just to be on the safe side. If you know how to solder this is an easy and inexpensive fix. If you don't know how to solder find a friend who does. These caps have positive and negative terminals. It's important you solder the new caps in with the correct polarity. Stiv0 gives instructions on this. Even if the caps aren't bulging this fix is so inexpensive, less than 10$, that you may want to try it anyway. I hope this helps you out.

Son sprayed cleaner on tv.


I have not a clue what to tell you, but doubt the cleaner is the cause of this. In any case the TV is so old you will not be able to get parts.

32" flat screen that went black


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Problem with proscan 19LA25Q


Watching a movie tonight...and slowly there was odd behavior from the screen. No volume at first, then flickering, fragmenting and now, as the others only shows the red power. I have noticed some strange flickering the past 2 weeks or so. I thought it may be the cable, so did not concern myself too much. I believed that was the problem tonight as well. But the screen is definately not responding to the remote or manual button.

Thanks
