Question about Philips Magnavox 51MP392H Rear Projection Television
My Hitachi will not turn on unless I unplug it from the wall for 5 or moe minutes. When I plug it back in I hear a "dong" noise like the capasitor is charging just for a second though. The tv will ten turn on. If I turn it off with the remote It chirps, and will not turn back on. I opened it up and it was very dusty, so I blew it out with 35 psi compressed air. I left it for a while to let any moisture dry and plugged it back in. No joy with the original problem. model number C50FD2000. I suspect it is the HOT. not the Convergence IC's. Since it will power on and have great picture if unplgged for a while. I might be wrong though. I would like to do the repair myself, I work on aviation electronics, so my skill level it a bit higher than the norm. Any sugesstion and/or ideas are appreciated. Also, where might I find a schematic and/or service manual for this model TV? Thanks in advance.
I fix a lot of Hitachi sets but have never seen this model--if you GOOGLE the model number--( I just did this) there is a site where you can download the service manual (not allowed to post it here) for free.
I would from your description guess maybe a bad solder connection in or around the hot transistor, driver circuit or at the HV transformer.
