Lc4441 projector repair


Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If you see any, replace them all in the power board section. Check to see if your TV is still under warranty first though.

The capacitors on the power supply need to be replaced. When you take apart the projector, and then remove the power supply (it's the section that the power cord goes to) and open it up. Look for the little can capacitors and see if any of them are bulging on top. That is the sign that they've blown. Replace the big ones (about 5) for about $5 in parts. Reassemble and test by turning it on. Search for YouTube video.

Hitachi 1350 projector dead, no power. cleaned everywhere, changed the bulb, nothing I do gets power into it.


I assume the projectors are of similar age and have similar useage history? Not certain why they would fail together, but the most probable cause is faulty switch mode power supplies. The electrolytic capacitors in these supplies a relatively short working life, especially when installed in high temperature environments - like a video projector. new caps in the supplies may be all that's required to solve the issue. If you have other similar projectors, they may well be approaching the same problem.

Any reasonably competent TV repair tech should be able to check the supplies for you, and repair them if found faulty :o)
