Question about Televison & Video
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.
PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.
Watch for power light to blink in a sequence:
1 blink-then 2 blinks-------no error
2 blink-then 1 blink-------X-ray protection
2 blink-then 2 blink-------SHORT PROTECTION*******
2 blink-then 3 blink---------deflection circuit problem
2 blink-then 4 blink---------vertical circuit problem
******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.
SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.
IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM
Let me know what you find as I am familiar with this set.

once any electronics refuses to turn on, such situation is known to be a power problem. In order to solve such problem, those things that are associated to powering the electronic device needs to be checked, starting from the power outlet to the components on the power panel.
First, you need to check if power is entering into the TV, after that, check the power board of the TV. There you will find, capacitors, fuses, transformer, etc.. If any of these power components are bad, there is no way the TV will turn on.
Therefore you need to diagnose the power board of the TV, test its components with meter to detect if any of the components are bad. After the diagnoses, you will discover what went wrong and you can proffer a solution by replacing the bad component.
You need to have a technical ability before you can do what I suggested above. Also, before you attempt opening the TV, allow it to cool, because TV stores current.
