We had a power outage here a few nights ago and when the power was
restored my Sony SLV-R5UC would not turn on, the clock was dead
ect.This problem has occured at least 7 or 8 times through the years
since I bought the VCR in the arly 90's. Has anyone else experienced
this problem?

I suspect the problem is the switching power supply. Does anyone have
an idea on what I could check in the power supply to see if it is
still functioning. The supply has had a lot of work done on it and I
would consider buying a replacement unit.

Does anyone know where I could purchase a new power supply and what it
might cost? Thanks in advance.

It's usually a small capacitor. You need an ESR meter to check them. You can
replace the entire power supply, if it's still available for about $200.00 so
you may *not* want to pursue that avenue.

I checked and the power supply is still available and in stock for $169.48
list. What a bargain,
Ron

thanks for the info Ron! I will try and replace most of the caps as I
have found out by reading that they are very troublesome in this
particular power supply. If there is anyone that can do this repair
for me please leave a message or send an email. I have problems
soldering small components because of my poor vision.

Just a quick note: These particular Sony supplies run MUCH hotter when the
vcr is turned ON. Therefore, don't just turn it on and leave it on when not
using it, and don't use it as a tuner for your TV. Adequate ventilation is
important as well.

Depends on the caps used. Later variants of this power supply used Matsu****a
caps, which are relatively reliable.

The power supplies that had trouble were the ones that used the Elna LongLife
caps, which are brown in color with gold writing. Your VCR might also have
Elna Duorex II capacitors, which are red in color, and are installed in a small
junction board (if your VCR has it) located underneath the mainboard and
positioned close to the front of the machine and sitting on a metal chassis.
All of these capacitors must be replaced.

I have an SVO-160 which hasn't given me any trouble except for the power supply
capacitors and other caps in the VCR, as well as the capstan bearing warp.
The power supply had to be repaired by replacing EVERY electrolytic capacitor
on the secondary side of the power supply. I also had to look in the VCR for
other leaky caps and, sure enough, there were more. This time, the caps that
leaked in a junction board were the Elna Duorex II caps.

Be sure that the power supply board and junction board themselves are clean of
any leaked electrolyte before installing the new caps to prevent future
problems with these circuits.

If there is anyone that can do this repair
for me please leave a message or send an email. I have problems
soldering small components because of my poor vision.

I could do it for you. I've done it before with my SVO-160. I do recommend
that you ship the entire VCR, not just the power supply. I am willing to bet
your deck may have those pesky Duorex II caps in them, which also are known to
leak and must be replaced. - Reinhart

Thanks for the kind offer Reinhart. Where are you situated and how can
I get in touch with you?

I rebuild these with the High Temp, Low ESR Switching Power Supply caps from
Matsu****a for $80 + Shipping. If you do this yourself go to Digi-Key and
order these series caps as they don't have the leaking oil like the Elna's.
The primary side of the power supply has two caps, a 390uf 200V and a 1uf
200V. The 1uf one usually goes and causes your problem. These you just
need to make sure you get high temp capacitors.

There are other things to check in your R5. The swing arm getting sticky
and replacing the battery backup, both are easy to care for.
