I installed a new power supply, cause set was dead,Now I get a red light but set will not turn on

Dead power supply. I recommend a new tv rather than throw good money after this old thing. A new power supply will cost $200 or so plus installation. Sometimes dead power supplies take other components with them as the voltage surges.

may be power supply need more information

This is usually caused by a failed power supply board. See

If you TV is totally dead set and no red light or green light on the front...


if that so the problem could be cause of dead set power power supply board...

You have 3 choices its either repair it on your own or took it to the technician or buy a new set of power supply board..

But for me I suggest to buy a new power supply board because if you took it to the technician cost of repair is almost or higher depends on the bad parts than the new power supply board...

But before you buy a new PSU please check this simple and common parts that usually cause of dead power supply board..

1. Transistor----Check if shorted
2. Capacitors----Check if bulged or leak.
3. Resistors----Check if open or change value..
4. Fuses---------Check if busted..

I hope this solution will be helpful..

Thanks for using fixya...

Hi I have a Sony KDF-55WF655 and I just installed a new lamp, now when I got to turn on the tv my power light flashes 5 green followed by 6 red flashes and continues to flash a series of 6 red flashes and has no pic, Any help would be great

Power supply board have dead capacitors.U know how to solders?Buy these capacitors to replaced them to have power back.Or u can buy a whole power supply board for the replacement at these websites Shopjimmy.com,Ebay.com for refurbish power suppply board.

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.

Is the it the power supply red light?

The red light may indicate that the power supply is too hot or is overheated. Therefore, you should let the power supply cool for several hours in a well-ventilated space. During this time, you should not try to turn the console back on to allow the power supply sufficient time to cool. As soon as the power supply has cooled off, the power supply light will change from red to orange, and you can turn the console back on.

If the power supply light is still red after you have let the power supply unit cool in a well-ventilated space, the power supply unit may require replacement.
Also make sure the power msupply is plugged in correctly.

You could also purchase a new power cord.
Good luck
