Philips CDR 795 Power Supply Problem

I get erratic operation that I've seen before. I was told it needed a new power supply. I sent the unit in when it was under warranty and it was fixed but now the problem is back. I'm getting the same symptoms as before. Trays may or may not respond to open buttons and other erratic operation. Does anyone know what it is on the power supply that goes. Capcitors and voltage regulators I know often cause problems in power supplys. I'm not using it anymore but I was thinking of fixing it if it's not too much of a problem and then auctioning it off on ebay. I may go ahead and test the caps. It has been a few years since I've worked with electronics.

I don't know what you are using to check the caps but in order to find the culprits, it's almost mandatory to have an instrument that will measure both capacitance and dissipation factor (DF) since that is what is killing most of our modern electronics.
If you don't find any caps pregnant or leaking deposits and plan on shotgunning it, I'd start with those with values between 4.7 & 100uFd as these are the most common failures and mostly in feedback paths and are lower voltages.
You can buy them at Mouser Electronics with no minimum charge and 'at cost' shipping.  
Good luck-

I have a harmon kardon cdr 30 cd recorder. After a power outage the unit no longer turns on. A surge must have blown something.


Hi
First thing to do is disconnect the unit from the mains supply for 15 mins to allow for a hardware reset,and then power it up and try again. If it does not come up, then the power supply has been damaged by a power surge associated with the outage. You may have no choice but to take the unit to an authorised HK repairer. Let me know how you get on with resetting the unit. Please take the time to rate this solution. Happy to talk to you more about it. Cheers
regards robotek

Philips 765 CDR - twin deck


Remove the 765's casing. If you don't have a star shapped screwdriver use a flat head which sits tight in the screwheads diagonals. Once removed, observe the 765's driver chip which sits behind the recording deck mechanism of the left hand deck. With the power cord disconected carefully remove this chip by gently working a flathead driver between the chip and it's base (the chip is not soldered to it's base but take care not to bend the pins) Once removed, power up the unit for a few seconds making sure that you do not touch the live internal workings. Remove the power cord again and switch the power button on for a few seconds(with no power chord attached) to allow the units capacitors to discharge fully . Gently replace the driver chip. Replace the cover and switch the unit on again. The unit should reboot and the gremlins should be gone.

CDR is not working


have a look on ebay for a cheap working donor recorder as spares are very expensive and very hard to get hold of.
i'm guessing your recorder either doesn't read discs, or it won't eject? which is very common and means either the servo board is faulty or the laser.

The following recorders i know off hand for a donor mechanism are:

MARANTZ DR-6050
PHILIPS CDR-775
PHILIPS CDR-770

if it proves to be just a faulty laser, all 3 of the above have the same laser unit.
if it proves to be a faulty servo board, all 3 have the same servo boards except if you fit one out of a philips model it will show 'PHILIPS CD RECORDER' on the display at power up but will still work nontheless.
obviously if a marantz is found it will show 'MARANTZ CD RECORDER' as normal.

hope this helps.

Trouble with cdr 570 philips


Newer discs are made with different dyes. We no longer get philips discs in the UK but Maxell 80 min discs work great in my 570. Have you ever been able to use 80 min discs? Usually if a machine only accepts certain types of disc it means the laser's power output is reduced i.e it's worn out so it may be time to find a new machine unless you can get a supply of discs it does use OK.

'Mr Audio' discs from Mr Data should be avoided at all costs.I can only use them in my Sony machines.

RECORD DROP OUT


Just bought this CDR 570 and not use yet.

Reading the instruction manual - yes, life experience has taught me some really useful stuff! -

Under 'Discs for recording' on page 7 it says at end of section

IMPORTANT:
To ensure proper working of the set we recommend the use of PHILIPS audio CDR and audio CDRW discs only'
Roughly translated I read this to me - 'don't blame us if the set don't work using other (non-compatible) discs' !!

Philips cdr 765


I just purchased one from Ebay. It plays fine on both sides. The recorder will recognize CDR's and the display will say recordable media. But, when I attempt to actually record, it won't work. I have another unit exactly like this one and the CD's I have work fine with that unit. I'm guessing this unit's recorder is bad? Any suggestions? Thanks.
