i have this tv...when i power it on i hear a click and the blue power light comes on solid if i then hit power again it goes to standby red solid
tv does not actually power on ..no picture..no sound..no fans...
when the tv blue power light is on ...if i look in the back of the tv on the main digital board there are a series of 4 blinking LED that keep blinking ....when the tv is in standby mode the led light on the board turn off........
according to service manual these leds should cycle on and then power off once tv powers on fine...
thereis a main digital board and sub digital board that are suspect according to other forums
the power for the fans comes out of the sub digital board.......and the power to the power lgiths comes out of the main digital board.....i think the sub digital board could be the issue however i did fine one large 400v cap on the power supply board that has a slight bulge on top..its definitely not pure flat like all the other caps on the baord..
...could this be part of the issue?????
any input would be appreciated...........i do have the service manual for this tv if that would help anyone
I got the same problem on my TV and found the same bulge on the same cap. Any luck replacing the cap????
would it be possible to get scans of the service manual? you can email to kc8gpd at hotmail i have the same tv with the same issue. luckily i have a stash of parts and will go thru and replace components till repaired. i could do it quicker if i had the service manual. you can add a HV whine to my symptoms.
