|
| Hi all,
I have one of these brilliant HDD DVD recorders and it's been a joy to own, until I accidentally blew it up! I'm hoping someone can offer some advice on how to go about repairing it. I have some experience working with electronics as a technician and hobbyist but I'm no engineer! I have nothing to lose though so willing to give it a try.. First the problem: It happened when I accidentally shorted the SCART connector on the back..there was a big spark and a popping sound and the machine lost power. I opened it up and noticed a glass 2A quick blow fuse had gone on the PSU so replaced it and powered up..it blew instantly again. So did 2 more. On examining the PSU board closer I noticed a big scorch mark near a diode (D5106) so I'm guessing that is burnt out and needs replacing..that might explain why the circuit is shorting out the fuse..? I do not want to remove the PSU board if I can help it which appears to be clipped down by those annoying white expanding plastic plug things... so my plan is to solder a new diode across the top of the old one, or just clip out and leave the legs in and solder the new one onto the legs. I looked up the diode in question on the board which appears to be a ERA 18-02 fast recovery diode 200/400V / 0.8A. Does my repair approach sound feasible? Maybe it's a more serious problem? |
