I do think it is a mistake mounting a HDD above a Power Supply though...
No question at all!

AND installed a second cooling fan which cost no more than "£5.00"
This forum is giving me hope. I have the DMR-E100H with the self test loop problem. Any idea whether the same fix would work (replacing part number STRG6353 on the PSU)? I've confirmed that the RAM Drive and hard drive are working. I've gotten the PSU out, but don't see anything with STRG6353 printed on it. What does this part look like (I've found it at several sites, but can't find a picture).Many thanks for the posts on the Panasonic DMR E85H dvd recorder on this forum and other forums about the : SELF CHECK : problem which goes into a continuous loop taking 10 minutes to 30 minutes before the recorder will sign on or may be just not sign on at all (DEAD) or other problems.
Mine developed this fault about 2 years after I purchase and the machine had very little use mainly recording to the hard drive. It finally died on me.
Reading the forums I decided to do the repair it myself
The problem is that it as a poorly designed PSU (power supply) NOT COOLING THE VOLTAGE REGULATOR…….IC part No. STRG6353 made by SANKEN ELECTRONICS in China .This is marked on the PCB board IC 001.
THE PART IC STR-G6353 CAN BE PURCHASED AT NIKKO ELECTRONICS FOR AROUND £5 EACH I bought 2 one for a spare over the internet with next day delivery………………………www.nikkoe.com
THE REPAIR
1. DOING THIS IS ENTIRELY YOUR OWN RISK AND I WILL NOT BE HELD RESPONABLE FOR ANY DAMAGE OR INJURIES INCURED.
2. DISCONECT ALL MAINS POWER AND REMOVE MOULDED TWO PIN PLUG FROM RECORDER.
3. Remove top cover….one large silver screw at each side…..three small black screws on the back.
4. Remove the hard drive top retaining metal cover which as the black ribbon cable also attached to it then pull out the ribbon cable from the hard drive CAREFULLY then also pull out the power connection plug to the hard drive remove hard drive
5. You will see that there is a plastic rubber moulded insulator to reduce vibration from the hard drive….remove this.
6. Remove the bottom hard drive retaining plate (four screws) to get access to the power supply PCB board.
7. Removing the PSU board (card)….Remove the small black screw where the mains electric enters the machine then lift off the multi jumper that conects to the main board pull and gently tilt towards you.
This should take an average twenty minutes at most to get the card out.
8. I took the card and the IC to a local T.V repair shop who took just five minutes to replace WHICH I RECOMMEND BECAUSE THE CARD IS DOUBLE SIDED WITH VERY SMALL SURFACE MOUNTED COMPONENTS WHICH CAN BE DESTROYED VERY EASILY.They charged me £5
9. RE-ASSEMBLE
Worked fine for me without having to replace any more components.
Hope this helps without getting ripped off for the repair.
help managed to get my board out but cant find the part i have to that look like the picture but none are ic one is d02 the other d03 can anybody help please
