Sometimes the convergence IC's failing will cause this. Also, the coolant for the picture tube can leak onto the circuit boards causing damage. Need to have it looked at asap as the coolant problem gets continuously worse.

My HD 1080 WS-55809 won't turn on - little green light comes on for 2 - 3 seconds, then nothing. It was fine - we were watching a DVD but had it on pause - the tv turned itself off - then it won't turn...


Hi


Thanks for using FixYa. Error code 2-2 means short protect which is either caused by bad convergence ICs and/or 2 Pico fuses (F9A05 and F9A04). You’ll need to open the back of the unit and replace the parts that have gone bad to resolve this issue.
Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

Your Power supply will most likely have to be replaced. Very common, the capacitor's inside these units due tend to get overheated and burn out. You can test power coming from the power supply with a voltmeter

Good Day, kammey;
Sounds like your TV is having a Convergence Circuit failure. NOT an easy repair, so, call an Authorized Factory Service Center to come to your home and give an estimate B4 repair, $450.00-$650.00, depending on your location and the cost of gas. Good Luck, big IRISH.
