KP-53XBR25 SONY COLOR REAR VIDEO PROJECTOR TV
Can someone please help,for some reason when I turn the tv on the sound
works fine, But the picture flashes on and off. This does the same thing on TV or games or threw the VCR. The speed of the flashing is not consistant. The shop said it could be fixed for about two hundred dollars,I think most of that is labor. I dont have that kind of money, But I could maybe buy the parts and fix it myself with a little help, PLEASE can someone HELP, Thank You for your time! |

Ditto, given the fact that everything else is working and the tubes are
simply going into blanking off and on. Odds are very high that the picture tubes are worn out and the AKB circuit can no longer compensate. To start on this repair the AKB circuit will need a proper check of the drive and return pulse as the tubes warm up to confirm. For $200 they will take a huge loss, three picture tubes on a Sony XBR ~900 parts cost. |
