You may just need to replace a few components in your tv or there mmight be something loose. First part of the TV that usually shows up with a problem is the power supply. Check the power supply for loose soldering or leaking capacitor. If there are none on those circuit make your way up to the main board and have it checked.

probably had digital module, if it's intermittently doing to blinking green light, if not a blinking light, then probably solder connections on the board or yoke connectors.

two possible problems:convergence IC(2pc),or hi voltage output:transistor,flyback,capacitors.

Dear Sir,
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times.
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source)
1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 PART # 283P044020 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. I hope this helped.
Good Luck, big IRISH.
