Display flashes "loading" hdd starts but machine doesnt respond to remote or front buttons dvd drawer doesnt open when asked and machine refuses to do anything will just flash if left and doesnt shut down there were 2 capacitors in the power supply with raised tops these have been replaced but fault still persists any help greatly appreciated
Replace D5103 and D5105 ( Under Heatsink! ). As a precaution replace C5103 and check R6108 and R5109. Any electrolytic capacitors with domed tops should be replaced. This fix also cured machine that flashed the DVD and HDD lamps but had no other functions.

Re: jvc dvd/hdd recorder model dr-mh20sek
OK changing the caps only resulted in proper filtering and voltage smoothing and did very little to solve your problem. Now what swollen caps are a sign of is an over voltage condition. what I would suggest because you may have a bad voltage regulator, is that you have to get a schematic and measure the voltage levels on the power supply to determine if they are correct or not. This will tell you if the regulator is bad or not. You do have a power supply problem you just have to determine where in the power supply. This can be done with the schematic and a voltmeter.

Yes there is a high probability that the 5v power supply has suffered damage. Anyways just check if the drive is ejecting properly without placing any DVD. If it doesn't then its confirmed that the ps is the culprit. try it and let me know..
Hard drive issue or power supply. Power supply prone to bad capacitors (look for leakage/swollen tops)
If hard drive faulty you'll need a new one which is no small task. Disk contains firmware and custom file system and smallest I've got image is 10.7gig
Just had the 2nd diagnosis for the error - "digital PCB" at a cost of £252 - BONKERS! Have e-mailed JVC to see if they can make the cost of the repair reasonable, got a positive reply they want me to send my proof of purchase, serial no etc. & they'll consider dropping the cost significantly. On top of that just found same model on ebay, ex display £130. baught it, was prepaired to pay upto same for the repair - gunna swap HDD for mine when it arrives, the stuff on there was the main reason i wanted it repaired. Still gunna try to get mine fixed for nowt though through JVC! May as well try for nothing!
Is there not a drawer open/close button?
Please wait usually indicated wrong type of disk and it is not being read or faulty laser.
Switch it off and switch on then press the drawer release before it starts trying to read.
