IF model number posted is correct and green power light comes on for a few seconds and then goes off: On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.
Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.
Let me know what error code is found and I will tell you what it means.
not knowing model number I will suggest a few things: if green power light comes on for a few seconds and goes out:
On front of set press and hold both the Menu and Input (device) buttons at same time for at least 5 seconds and release both.
Power light should blink a two digit error code like 2 blinks,,2 blinks,, a pause and repeat it several times.
This is a error code that indicates what area problem is in, let me know what error code you find and I will tell you what it means----if set has been unplugged you will have to try to turn it on and let it fail before you go for the error code.
Try pressing in both the menu and device/input buttons in together on the front of the set and hold for 5 seconds to see if the led will blink a two digit error code such as 2 blinks then a pause then two more blinks followed by a pause which would indicate a 22 error. Then let me know what the blink code was if any.
have you tried to access the self diagnosis feature by holding the menu and device/input buttons on the set both in together for five seconds to see if the led will blink a two digit code such as two blinks pause two blinks for a 22 error? Try that and let me know the blink code and i can assist you.
press the menu and input/device buttons both in together on the front of the set and hold for 5 seconds and then see if the set blinks a number of blink pauses and then blinks another number such as 2 blink pause 2 blinks which would be a 22 caode. It then repeats that code.
