Dear friend i have a question for you. do you get sound?
if you do you may have some bad caps or there is a 5volts regulator that goes bad sometimes and you get no picture.
lets start with this...

You've got a bad solder connection,or broken foil line,s on the pcb (printed circuit board1.gif).Narrow it down by pressing in different places,or use plastic or rubber tip.If not,then you got a shorted load on this fuse and diode.do you have a schematic,whats at the end's of this circuit.D represents a <Diode> not a transistor.

Mitsubishi model Wt-46807 Power shuts down after turning on. Tried the solution of pressing the menu & input buttons at same time for at least 5 seconds. Power light error code was 2 blinks/pause 2...


hi,
Error code 2-2 indicates "Short Protect Circuit" problem in tv.
Need to check pico fuses in power supply as one or two got blown due to bad convergence chips.
Below is an exploded view of tv chassis, power supply and convergence area has been marked to give you better idea to look for pico fuses.
Unplug tv from wall socket before to repair/check any thing inside tv.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

Sony rear projection tv model KP-53V15 turns on, have sound but no picture, after a while, picture comes on, but later goes out again, picture keeps coming and going. Where do I start looking?


Adjust Screen Volts (G2) of all 3 picture tubes and screen volt control knobs are on focus block located under speaker grills at front of TV.
Remove speaker front grille of TV, look for focus block that has 6 control knobs, 3 knobs are for focus and 3 for screen volts, increase volts by turning little bit control knobs of screen volts and this will solve your problem.

Sounds like you have a jammed / shorted out button on the control panel... Try un-plugging the tv, and then unplug the "button panel" on the front of the tv...see if you can turn the tv on with the remote. Sometimes if one of the buttons gets shorted, it will "lock" the processor from doing ANYTHING else, as it thinks you are holding down the defective button. If this works, simply have the defective switch or control panel replaced, or just leave it unplugged and use the remote only! Hope this helps!
