Question about RCA VR629HF VHS VCR

1 Answer



Need some advice on a vcr (power supply ?) problem, sure hope you can steer me right on it.

It’s an RCA model VR633HF, four head, nearly 8 years old. For over a month now, when I
try to turn it on (with a recording tape in the carriage) with either remote or the on/off switch, it begins
to bring the carriage up to the drum, then abruptly stops, upon which the LED display starts flashing,
with a ‘tick-tick-tick…’ sound occurring, synchronized with the LED flashes. It does this for some
3 – 5 minutes (no controls will stop it), then stops and shuts the unit off. Usually, if I turn it on again,
it starts, and every thing is normal, but sometimes I go through this THREE times to get the unit
on. When it does come on, the LED flickers a little, and the clock time must be reset. Strangely, with
a pre-programmed recording, it powers on fine, and the program is recorded, however, it still screws
up the clock after. I have tried pulling the plug (reset the cpu) several times, to no avail.

I asked a local service tech here about this problem, and he told me it was a defective power
supply ( the SMPS type), but didn’t tell me what in the circuit to look at. I don’t have the schematic/
service manual for the unit, I do have a DMM. Later I was told that the power supplies in these units
are enclosed and plug in to the main board, and from reading online, that the problem could be with
leaky/shorted diodes or filter capacitors in the rectification part of the circuit.

What specific components are defective here, and could you give me an idea what the circuit looks like,
so as to locate the parts, etc. ?

Thanx loads for your time, patience and help in this,

Chris Curran

On vcr power supplies usually first component to go is a capacitor, check if its blown, or test it if you have a meter capable, next check diodes and resistors, also check the resistors and diodes on all the boards( they may have blown if a cap has blown) If there was smoke or a smell its usually a resistor to look for. When you replace them replace them with a higher votage cap.. Example 15v 1000uF cap with a 25v -35v 1000uF cap( this is just to avoid the problem from happening again.

How do we hook up VCR to TV

  1. 1
    Turn off all of your components. This will help prevent any accidental damage while connecting.
  2. 2
    Connect the RF/COAX Out port on the VCR to the RF/COAX/ANT In port on your TV. Use a coaxial cable.

  3. 3
    Connect your antenna to the the RF/ANT In port on the back of your VCR (optional). This will allow you to watch over-the-air broadcasts through the VCR.

  4. 4
    Turn on the VCR.

We have a RCA VCR Model VR622HF Manf. 9-18-98 that suddenly won't turn on manually OR with remote. I am an experienced Electronic Tech with 43 years @ ATT. I measured the resistance at the AC Plug and read...

If front display lit up when vcr plugged in that means power supply is working and issue is in system control section, and if front display remains dark while vcr plugged in wall socket then power supply is defective.
As you know its an old model vcr so I do not think spare parts would be available any more, I found good option for you to fix this vcr.
Click link to get same vcr in working order for $40 that can be used to obtain either power supply or any other board/ parts to repair your vcr.
Hope these info will help you.

I do not have power but I verified int incoming to the board and the fuse is good. Where is the power supply circuitry

the power supply starts at the plug and, extends along the edge of the vcr to the front; it has a heavy line and, the word: "hot" printed on the circuit board; separating it from the "cold" DC side of the VCR circuit board.

RCA DRC8320N DVD Recorder/VCR


Seems to have no power, no lights on front lit, if listened to closely one may hear a "click click click" sound.

Solution: Replace C232 on power supply board.

Additional technical info:

In this design, the switching power supply feedback is from the 5 volt standby rail only, which is odd. The problem is caused when C232, the first filter capacitor in this rail and the sampling point for the feedback circuit, opens. The clicking sound is transformer rattle as the power supply restarts repeatedly.

RCA VCR makes high pitched whining noise when it's on...

The power supply is starting to fail. There are a number of capacitors in the power supply that need to be replaced. A local repair shop should be able to fix this easily. Figure on $10 max for parts.

The power supply has some bad components in it. This is a "switch mode" supply that means that simple fail;ures can show up in odd ways. Usually there are capacitors that go bad in these. Search the web for "repair kits" for these models. These kits will contain the most common replacement parts for the power supplys.

VCR says safe

Hello. Have you tried unplugging the power from the VCR for more than 24hrs? This may resolve the "safe-mode" feature going back to "default" and permit regular use after this amount of time elapses. That is kind of unusual for the stepping upon the remote to cause this?
