My toshiba 40sl412u turns on for a second then off


You more than likely have faulty capacitors on the power board. the caps won't let the power build up.

the general steps are
  1. unplug your tv.
  2. lay it glass side down on a soft thick blanket to protect the glass.
  3. remove the rear panel.
  4. identify the board with the power connector.
  5. remove it.
  6. find replacements for the electrolytic caps, the cylinders looking ones.
  7. unsoldier, then resoldier the caps.
  8. put the TV back together
This will generally cost $10 for the caps and less than $50 for the soldiering equipment. You tube has a vast number of videos on this.

a tv repair shop locally should cost less than $100. should be even less if you remove the board and bring it to them. there are companies that you can send the board in and they will repair and send it back.

Mind you $100 is cheep VS a new tv. I replaced the caps in mine for 10 bucks and a few hours of time, but I'm a highly qualified electronics repair tech.

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.

When I turn on the TV it has a loud squeal for about 10 minutes until it seems to warm up.

Polaroid tv wont come on


user stiv0 has the solution-go to tips and there is step by step on how to change capacitors-i fixed mine today and took me less than an hour and supplies costed approx. $10.00. I used 1000uf 35v caps since i could not find 10v or 16v. Works perfect-just like new and no loud noise. Just be careful when removing old caps-the wires are thin so try and make sure you get each piece out so you can put in the new ones. Good Luck

the noise is probably due to bad caps-stiv0 has tips on how to change capacitors. I had the same noise and tv would come on after plugging and unplugging but eventually stopped coming on. I just changed the caps and now it works perfect and took approx. an 1hour and supplies cost approx. $10.00. Good Luck
