I Have a 1987 46" RCA Projection TV that keeps blowing a fuse. The sound stays on but the picture is blank. It flashes a red screen then goes blank. I change the 2 Amp 250V fuse and it is back on. Everything works perfectly. Is there someone out there that knows what the problem is or who can help me diagnose the problem. It has a hitachi chasis and I have the schemadics. Thanks
Its gonna take a lot more input and info than that. So unless you have more understanding, not really. The good news is that fuse popping is one of the easier types of fault to locate and fix, usually. Regards, NT
The Tv is a 1989 ColorTrak 2000. It has a hitachi chassis. Model number P46000T The repair person who took this in and just put the fuse in without any other diagnoses said it could possibly be a burned 1K resistor near the EHT. (i don't know what that is) or it could be a drive problem that effects the transister that makes the fuse go out. Also another possibility could be a high voltage splitter problem (169). Does this information help you? The repair guy said unless it starts to smoke and something actually burns out that it would be hard to find the problem. Do you feel the same way? Thanks A lot, Val
OK. Type of power supply, which section of the circuitry is drawing the excess current, which components are overheating, if any, test results for the LOPTr, whether EHT is present, and so on. Basically information only a repair peson would be able to find. From what you say I'd pick another repair person, and always always pick the free quote. Regards, NT
