Help me with my Sharp 32LS400. Audio is good, but the picture is not clear and flickers. Can see the images, but is annoying. Just can't afford to buy a new one right now. I read somewhere you could Resolder flyback pins, but have no idea if that is right or how to do it. Your help is greatly appreciated. I promise to share your site with everyone I know if you can save my wife from buying a new flat screen! Rex Roberts

patrioticdog-I have just answered a similar problem, you can remove the back and find the flyback transformer. The big part with the round rubber plug hooked to the pix tube. there will be two controls on the flyback one for focus one for screen. turn up the screen ever so slightly,your screen will brighten up.Also if you check the main pcboard ass'y there may be a sub bright control same thing small adjustments. maybe tell the guy to give a bit off cause of repair ,good luck let me know. cooltek Feb15/08

SOURCE: high pitch

I have never heard a tube make noise when there is a good picture. Anyway, the noise has to be a transformer ringing or oscilating. They make a high pitched squeal when they have a loose winding or their cover is loose. You probably won't be able to feel or see anything loose on these transformers The power supply switching transformer is the first to look at. Take a hot glue gun and just cover the thing...especially at the base of it. The next (and only other) one is the horizontal drive transformer.It is located close to the high voltage transformer( biggest thing on board and usually in back or corner of the PCB.This one wont squeal) The horizontal drive transformer is about the size of a large marble and is encased in a black plastic cover. Cover it with hot glue also.
If you take the back off you will probably be able to localize where the squeal is coming from. You will probably need a signal to hear the noise also. After you find where it is coming from UNPLUG the set before doing any hot gluing!!!!
If you 're not up to this procedure take it to a technician. Your tube is not going bad and the set is definitly worth repair. Simple fix!! Good Luck!!
