Bad convergence, now wont turn on at all.

I have an older ws-55311 and the convergence woudl have to be re set every time you turned the tv on and sometimes it would just go bad while watching a show. then the other day the tv just shut off and now when you go to turn it on it just turns the green light on and then it goes right back off, no picture or anything. What could this be?

Green lite turns on for 2 second and then turns


Please listen and try this:

When the power light comes on and goes off, on the front of the set press BOTH the Menu and Input (Device) buttons at the SAME time and HOLD them both for at least five seconds and then release both.

The power light will blink a two digit error code and will repeat it about 5 times. To get it to repeat you would have to unplug the set and turn it on again etc.

The most common error is 2 blinks, pause, 2 blinks.

Let me know what error code you find and I will direct you as to what it means and what may have to be done.

I HAVE A WS55859 , TOOK IT TO A TECH AND HAD 7 CAPS REPLACED BECAUSE OF BLINKING LIGHT AFTER POWER OUTAGE NOW AFTER 150.00 SPENT THE TV IS NOT BLINKING ANYMORE ONCE I TURN THE SET ON IT WONT STAY ON IT...


Did the set work after the tech replaced the caps?
Is the work under warranty?
Bad convergence amps would be the first suspect.
Press and hold the menu and device buttons at the same time on the set (not the remote). The led should blink an error code. If it blinks 2 times then 3 times, it is probably the convergence amps.

TV WON'T TURN ON


You might have a bad power supply or convergence circuit, I also suggest you to check for fluid spill on the circuit board. if the convergence is defective one of the 5A picofues on the power supply is open. Hope this help you.
