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.

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 30V 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.

Blinking green timer light on front nearpower button keeps blinking, tv will not turn on, unplugged for 24 hours and tried again, also hit system reset and still nothing.


Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.

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

Polaroid hdtv flm 3732 37''


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

Sanyo 24" flat DS24425 suddenly turned off, won't turn on. Pressing the power button either results in no response or it turns on for a second, then turns off again. No picture. Already tried playing...


Solution to the won't turn on or turns on and turns off in 3 seconds thing...as my Ds24425 did.

First thing is very important...unplug the TV and let it set for 24 hours before you proceed.

The voltages inside a TV are EXTREMELY HIGH and LETHAL....so proceed with caution!

Place the set face down on a towel on a table and remove the back cover....hex screws around the perimeter and 1 phillips screw near the inputs.
The main board will slide up and out. unplug the degausing coil "white plug with two wires" and the speakers connector. This will make it easier to turn the board and take a look.

What I found with mine was a bad electrolytic capacitor. You can identify I bad cap "capacitor" by examining the tops of each one for bulging or signs of overheating "melted or bubbled plastic covering." The cap in question was C626 with a value of 1000uf, 16volt. I replaced with a 1000uf, 35volt and it works perfectly. The cap is located about center of the board. Carefully unsolder the cap and remove, make sure to install the new cap with the proper polarity...the board is marked with a dot indicating the negative lead of the cap.
Be sure to reattach the white plug and speakers connector and slide the board back into the plastic grooves. Then replace the back cover and test. Good luck! ...Daddio
