Sony bravia 32" lcd tv won't power up

Crack open your power supply again and take a look to make sure all caps are intact and not blown or bulging. Next check the main board for any possible caps and resistors, not likely as there is an external ps but possible. If you don't see anything odd then there may be an issue with the controller chip in which case you could replace but it would probably work out to the same price as buyin a new tv

Got a Sony Bravia 32 L 4000 3 years ago and worked fine untill now. We have a double image , one partly over the other one. Anything we can do to fix it?

No this is what we call a "convergence" problem, it is due to burned out component(s) on the main pcb board. You either will need to get it repaired or replace it, replacing it will most likely be the best option.

Bravia wont power on

Good day!!!!

TV won't power ON..

This is the common problem..

Power supply board or main board..

Please try this procedure to determine the faulty parts.

  1. Open the back cover.
  2. Check the input of the power supply board it should have 220vac or 110vac depends on your voltage comes from the outlet.
  3. If you don't have voltage input of PSU..Please or try to replace the power cord.
  4. If you have voltage input on PSU..Please check the output voltage of it..It should have 5vdc for the main board,12 or sometime 16vdc for the audio and 24vdc for the inverter board(back-light).
  5. If you encounter voltage drop on the output..Please check the power supply board if have leak/bulged on the top capacitors..Please replace it with the same type,ratings and value.
  6. If the 3 voltages mention above are normal..Your main board is defective you need to replace it because main board is not for D.I.Y repair due to the surface mount type parts on it..

I hope this solution will be helpful..

Thanks for using fixya...

Sony Bravia KDL-32V2000 LCD TV switching off and on by itself

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Sony bravia LCD KDL52 TV: blurred picture with color bands

It is most likely the TCON board (located at the top right against the LCD panel). When these boards have problems, they can act up when cold or warmed up.

You will want to check with any extended warranty company you might have, or Sony's part website for the availability of the TCON board.

The problem here is, sometimes those TCONs are not made available separately and need to be replaced with the screen.

If you have to replace the panel, buy a new tv. You'll save yourself a costly repair.
