Hi. Please help, I have a Panasonic DMR-HS2. The unit doesn't work, it goes back to its standby mode (clock on screen),and the disk tray wont open. The unit wont play and always goes back to its standby...
Sounds like a typical communication error between power supply and main microprocessor, resulting in the unit continuously reverting to standby with no other functions accessible. In this case, the power supply has several faulty/leaky components (no shorts or there would be no clock display at all). Always a good idea to target the PSU in these units first, to eliminate any suspects before diving into the microprocessor (which, I might add, is a high-density surface-mounted IC with pins on all 4 sides and it is glued as well as soldered to the main board).
In the PSU, it is possible many electrolytic capacitors have gone funny, bulged, or leaked. Check and replace ALL caps as required; not just a couple, and check the IC regulator (IC1 is usually a problematic device in many DVD recorders). This IC is usually prefixed with STRxxxx (where x represents its type number) and is a 5-pin standard device. This is obtainable as a part. The cost will depend where you get it from.
If you are not tech. savvy, I suggest you submit the unit to an authorised service centre, for a quote, and a second opinion (on the likely causes and/or how many components are involved in the fault as well as economics of the overall repair), then make a decision afterwards, whether it's worth fixing or not. Up to you, but be warned, it could be an expensive exercise either way.
