No sound and black screen on my Hitachi 57F500 57 in. Rear Projection HDTV-Ready Television. But if you hook up a video game console you hear sound.


Hi
;
Have the unit serviced you have no high voltage going to the picture tubes. The most common failure part to suspect is the Deflection Board.

My Hitachi TV Model #51F500 is showing shadows and double lettering (in other words a terrible picture). Please help.


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Colors r seperated n the top and bottom of picture r curved


HI:
This is a convergence power supply problem on your deflection board. There are 2 small bias fuses on the deflection board that has blown, usually this is caused by bad connections on the flyback transformer, it is also possible that the convergence power supply has failed also, but normally on this model open micro fuses on the deflection board is your prolem.

Please leave comment if more info is needed.

Hitachi Projection HDTV Convergence Problem


If you have the schematic diagram, look for the deflection PWB. The STK392-110 ICs are mounted on 2 heatsinks, in order to remove the parts you will need to unplug the deflection PWB from the chassis.

Magic focus


That's a DP23 chassis, why replace the deflection board? Does magic focus come on the screen? Does it just no converge the picture? If so, it's likely that the convergence amps have failed.
That unit takes two STK392-110 Sanyo built Ics at board position Ic04 & Ic05. If you replace them I'd upgrade to the STK392-150's for greater reliability.

Is this a Hitachi set? If so then check the model number and be sure it's right.
