Hi, recently I bought this DVD recorder off eBay. The seller said it was in good condition.
I tried to use it as a passthrough and I noticed the picture was extremely noisy. I'll put a short clip recorded from the Playstation 2 menu, but the same goes for VHS and Laserdisc capturing.
This recording was made with the YPbPr output, but the same happens with composite and S Video output. Also, both composite and S Video inputs in every port have the same problem.
Then I opened it, and I saw two leaking capacitors inside, nothing else (except dust) seemed wrong. I'll also attach pictures of the caps.
So here's my question. Are the failing capacitors the reason why the video output has noise?
While the effect they have would depend on their location in the circuit, they certainly are not doing your image any good and they should be replaced. (The more common issues were with surface mounted caps, these appear to be through hole radial lead mounting. Generally easier to replace if you are into DIY. )
If a couple have failed, others may not be far behind and checking with an ESR meter might help identify if there are more that need replacement.
Are they in the power supply portion of the circuit board?
However, you may want to exercise your ebay return/refund since it obviously is not in "good condition" - if it is not too late. There may be bigger issues than a couple leaking caps and you will not know that until you dig into it.

I think it's all been covered, but without instrumentation, you can't really determine the health of capacitors, I'm sure dplaomaki like myself has seen many, many caps that look perfect but are really cattle trucked.
