Question about Sony KP-EF41 41" Rear Projection Television

No picture at all!!! :(

Hi guys i have had this tv for about 6 years and its worked perfectly untill about 2 weeks ago.

Theres no picture at all, no menu comes up, but there is still audio. Whats the most common thing that could have happened?

do you recommend i open it up and check for loose connections, or should i just call a qualified technician to take a look, any ideas on the price for a fix?

    Thanks for the reply.

    By tubes do you mean the 3 light globes?

Hello ramis,

The symptoms you have described could indicate a problem with the HV section of the TV that supplies voltage to the CRTs (RGB Tubes) if this is the case I would suggest that you let a qualified TV technician work on the problem.

    Hello ramis,

    Yes they are Red Green Blue Cathode Ray Tubes, they are supplied High Voltage from a transformer located on one of the boards. I believe that this or its associated circuitry is the problem.

This sounds like a common problem on these TVs (it's happened to both of my AOC TVs a couple times). Try a factory reset:

1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote)
2. Using the other hand, press the Power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and Enter.
5. Power off and reboot the TV and Computer.
6. Run channel auto-scan to regain the picture.

I have the same TV which had the same issue ( green in picture ) - back on 10/2007. I called Sony. They had their technician replace the optical box ( factory defect ). There was no charge for the repair even though TV was out of first year of warranty. Call Sony.

Television picture issues...

I had the same problem when I accidently hit the remote. If you are hooked up to cable make sure INPUT is on the correct setting -- AV, S-Video, YPbPr1, YPbPr2, VGA, HDMI1, HDMI2, ATV & DTV (see button on TV or remote). Hope this solves your problem.
