Has anyone got a circuit diagram for panasonic DVD vcr

The circuit board may look good, but a power surge can damage the tiny resistors, diodes, and transistors. Any one of those mention can render the unit inoperable.

unit goes in to self checking over and over dvd can not be ejected and will not function at all?

If you have the remote for the unit, with the incoming cable connected to the unit, on the remote, press menu/set up button, once in channel set up, select auto search...it may take a couple minutes for all the channels to be found...once complete, select done/exit, or press the menu/set up button again to exit.

any questions, let me know.

Hi Keith
As long as the diode will physically fit, you can virtually use any infrared replacement. Just look for an infrared diode that looks similar and fit that. Should be ok.

Send an email to: [email protected] and write "Panasonic DMR-ES30V repair brief" in the Subject field. Tell Mike your problem and he will send you his repair guide.

Basically you need to replace two capacitors in the unit.

First of all,i don't know if you have a combo dvd/VCR player or two separate units.Secondly,please tell me how you connect your dvd/VCR combo OR DVD player and VCR player to your TV.

either your toggle is bad or the dvd mech has a problem...

Unit dead.
Local repair shop said it's un-econimical to repair.
Admitted they had no service manual.
Said they could 'have a look' but likely repair cost would be over $300. Charged me $50 for quote. Useless Gits.

My opinion & findings.
Power supply sensative to spikes.
I Suggest a power filter in-line with unit.

Disconnected all sub-boards from main.
Hiccuping PSU (5v wobbles between 2&3V).
Replace switchmode IC & feedback IC. No change.
Eventualy identified short-cct diode as listed below.

0402-001194 Diode is a Gen-purpose 200V 2A diode. I used a 1n4007 (1A), so I expect to have to replace it in future. It's "D1S35" located very close to right rear corner of main board, part of 15V and 12V rails. Next time I'll use a 'faster', higher rated diode.
I also had no clock progression. Time could be set but would not advance. Been like that for ages - I thought it was a user clock-setting error. Identified Dead 32.768 khz crystal (XT601).

Hired manual $10 +postage
Non-faulty parts + postage $40
1 diode $1

Satisfaction, plenty.

Read a post from tech-net.archive.net for the values:
d1o41 20vz diode - shorted
pr1005 1.5A ic protector - open

Please post if your repair worked!

The power circuit for the DVD and the vcr are separate look for a open diode and transistor in the circuit that supply the DVD.GOOD LUCK.
