Question about Panasonic AG-DS555 S-VHS VCR

1 Answer

Seems like TBC won't lock, blue cast, picture unstable, weird colors, no contrast

I just got this deck and I love it. I'm a ham guy/computer tech., have solder station, can perform surgery.
You mentioned replacing all the caps on the vid boards. Before I do this, I notice lots of internal trim pots. Is it possible the unit needs a tune-up? Seems to get more stable after warmed up -- jog/shuttling back and forth will eventually get it to lock on. Does it playing tape as well as video in, so I'm convinced it's in the output somewhere -- TBC, video out. This deck won't let you turn the TBC off? Tried the setup procedure from the user manual for the TBC. Any help appreciated. Sounds like you really know your stuff. Actually, mine is the AG-DS550. Cheers, Duncan McAllister

Change in stability after warm-up is a sign of defective capacitors. the DS550 and DS850 both are notorious for capacitor failures. don't touch the trim pots unless you have a service manual and a wfm/vectorscope.

What is the purpose of an R2 filter?


Each filter intensifies its color and darkens others, especially the color opposite on the color wheel. They're not of much use in color photography, unless you want weird color casts, but they come into their own in black&white photography.
For example, a red filter intensifies red and darkens blue. It can make a sky look almost black, making clouds pop out. Similarly it can darken foliage. A green filter on the other hand will brighten foliage.
If your camera can take black&white photos, try taking pictures of a red rose with green leaves with and without the filters. With one combination the rose and the leaves will be the same shade. With a red filter the rose will be bright against the dark leaves. With a green filter you'll get a dark rose with bright leaves.
With digital photography you can achieve the same effect in postprocessing, but some times its easier to get the result in camera.

Contrast really dark but seems to improve after the tv has been on several hours


Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

I have a canon EOS 450 and on a recent trip to Iceland, clear light but lots of lying snow, most of my shots came out with a very blue cast. I had a UV filter attached. Can you help?


The UV filter should have been OK, in fact it would have decreased the blueness - The OES has a 'snow' setting I thought - what this does is change the white balance.
If your pictures are now on the computer try and change exposure setting , and also contrast.
By reducing Colour Saturation (removes blue) you will also loose some sky color.

Screen is now a weird color


The problem might be in the cable. Try to reconnect it to your machine. Also try to set your color settings on the monitor itself, so that all the colors are equal.
