Question about Televison & Video

1 Answer

I have a Sony Wega KDF e55a20. The problem is when I turn the tv on the green light blinks a few times and then the red light blinks 6 times but nothing else happens. I installed a new projector lamp and checked my installation. I noticed that there was another thermal fuse fix for the 60" model and I removed the fan and tried to locate this fuse but apparently this model does not have one in the same location. Can anyone get me back on the right track?

    Hi: I am reading various voltages there. Can you tell me where the 6 VDC source pin is located.



    Thanks

    Hi: I checked the GM Board and it does have dc voltage which would indicate the power supply is working. I'm not sure the location of the 6V source so I can't check for it specifically. Do you have a schematic or board layout I can refer to?

Hi,
KDF-E55A20 has self diagnostic feature and 6 times blinking is an error code that indicates problem with GM Board (power supply board) located at left side of tv if you see tv rear.
This is not fuse or any thing else, check GM board that is defective and not providing DD 6V output.
Replace GM Board to solve tv problem.
Hope this will help, let me know if you have additional question.
Thanks.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL-2200.Have a blessed one!
