Philips/Magnavox TV Schematics
I have an inoperative Philips/Magnavox TV set and no schematics. Where
can one go to find/download/purchase schematics and maintenance documentation? I think it took a hit a few months back when we had a power outage. One of the components let all of its smake out, but upon opening the set up, its not evident which one. Nothing works (not even the pilot LED). Its a chassis no. 25B800-7562 -- Paul Hovnanian ------------------------------------------------------------------ Tech support: Do you have any windows open right now? Customer: Are you crazy? Its twenty below out! |

Paul:
The schematics may be of little help unless you first can do some basic troubleshooting and testing without them. There are NO step by step troubleshooting procedures and the schematics are only most useful to those who are experienced in television repair. A dead set due to a power surge is usually one of the simpler repair scenarios. Obvious first steps after your visual inspection would be dust off your DMM and to test the power supply components and look for properly regulated B+, in addition you should test the HOT to see if it is shorted and test for other faulty components in that area of the cicuitry. You may want to go to the website for this newsgroup at www.repairfaq.org there, with some of your search time, you will find a weath of repair, troubleshooting, testing and safety information.

I've done quite a bit of electronics repair (and a little bit of TV repair), and I wouldn't start poking around in something unless I had some idea of what sort of circuit I was looking at. I'd much rather rely on a schematic than trying to trace the power supply around the traces of the main board. -- Paul Hovnanian ------------------------------------------------------------------ A vacuum is a hell of a lot better than some of the stuff that nature replaces it with. -- Tennessee Williams |

You do not need a schematic or service manual to check and test the
components that Sofie indicated in his reply post.

THANKS! I may check that out myself. I've got a few things here I could sure use a schematic for to finish up. Lou |
