Question about Sanyo PLC XU32 Multimedia Projector
Ok the subject heading just about sums up this recurring problem. Every 10 or 15 minutes or so the screen just goes bIank (except for lines down). Sound is normal and everything else is fine, menu and all other on-display messages are normal. I can hear the fans working and the machine does not appear to be any hotter when the image disappears. There's no blocked ventilation and the filter is clean. Any ideas?

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck

SOURCE: Sound cuts out periodically
Sounds like a poor or cold solder connection in the sound circuit. If your not a tech, this repair really should not cost an arm and a leg to repair , but maybe your first born??LOLOL No really if you have no solid state repair experience please seek out a local repair person to assist you in this repair.

SOURCE: PROJECTOR POWERS DOWN
This would appear to be a bulb that has reached end of life -- or the projector thinks that it is because of hours. Usually most bulbs are 1000 or 2000 hours. Depending on your projector there are different ways of checking bulb life hours -- if you Google your projector model number and "bulb life" you will usually get a post on how to check these hours. Also, if it is a new bulb and you haven't reset the hours counter, it may need to be reset (however you also don't want to wait too long before changing a bulb that has reached EOL since they can and do explode sometimes taking out the projector with it).

Sounds like you have bad solder joints on the vertical ic which should be numbered IC501 on the board.also there are capastors that coud be going bad but i would look for bad solder joints on ic frist.
The capastors numbers on board are C502 / C516 also need to check R 483 which is a resistor.
resolder the ic if you know how to solder. That is a comon problem a lot of tvs out there have. The only thing is the tv has high voltage on it even if it is unpluged from the wall. Some of the capastors hold there voltage for a long time. Be sure and unplug tv before you try anything if you are going to do it yourself and stay away from the capastor in the AC line should be marked 200 V or moor.

the two AV1 and AV2 have different inputs on the IC,
the first port has a disconnection,
take your tv for a check up
