Question about Hitachi 50UX57B 50" Rear Projection Television

1 Answer

Zenith pv4663mk The sound keeps going out, if I get up and shake the tv it will come back, but normally only fora min. I know how to work on electronics, I just can't find any diagrams for this tv, could you tell me where to look, and what the problem might be,I am guessing it might be a loose wire or an old resistor that stops working when it heats up. thank you for your time.

Zenith z56dc1d dlp tv picture works for about 1 minute then starts shaking and tv shuts off

You may want to get it in a rather warm room and or remove rear cover and use a hairdryer to warm everything up inside the Cabinet--with rear cover off look to see if the fans are dirty etc and if they all come on, if a DLP especially look at the lamp itself and the fan that cools it.

Zenith dlp projection t.v. model#z52sz80 t.v. turns off randomly

This solution is for the zenith 56" DLP. Unplug the tv, either from the wall socket or the TV. While the TV is unplugged hold the power button on the TV for 40 seconds. This lets the excessive power drain from the TV. If this does not work call 1-800-243-0000. This is the number for their help line. This is the fix the tech gave me and it worked right away. Hope this helps and have a great day.
