Question about Panasonic AG-1980 S-VHS VCR

1 Answer

Good Audio, Bad Video

This is on a Panasonic AG-1980P. The video is dark, almost black (no chroma) and there is no vertical hold. I have another working unit and I swapped the entire K-Mechanism and head amp as well as the power supply with no change. Thus with the head, head amp, and power supply eliminated, the problem is in the main board somewhere. Is anyone familiar with this problem?

Sounds like a loss of luminance -- check the analog yc pack for bad capacitors.

Hi - I have a panasonic ag-7330 SVHS deck. It lights up but does absolutely nothing. The Video Rec Servo light is blinking constantly. Any ideas?


It could have a timer record present that needs to be cleared. Otherwise it could be the mode switch playing up. But that too can be caused by physical damage inside the unit, thus setting the mechanism in the wrong position. In other words it thinks it is in record mode when it's not!

Video noise pattern in playback panasonic AG 1980P VCR


It sounds like the video heads are dirty, or the tracking is off. I would first try adjusting the tracking to see if it can be corrected. If that does not work then I would clean the video heads using a video head cleaner (Radio Shack) You could also try a different tape to see if it that could be the reason. Also double check you video connections to your monitor to make sure they are good. If all of this fails than it may have to be checked out at an authorized Panasonic repair facility!

I hope this helps and good luck!

No video output


AG-DS555s are plagued by capacitor failure problems on all the video boards in the deck. Replacement of all surface mount electrolytic capacitors is the solution, but before you try that, give the heads a good cleaning. It's amazing what a miniscule amount of dirt on the heads will do.

Digital jitter during playback


The random audio/video breakup sounds like a tape path alignment issue. Best done by a repair shop.

Power down - F 04 error


These are good old VCRs probably in need of a belt overhaul.

Try unpluging the unit for 2 minutes and see if the error message is reset.

Vcr problem


Did you try cleaning video heads? Most obvious problem. Do you see the picture out of the VCR while recording? That would rule out cables, switches set wrong and most of the electronic circuits.

Colour Noise and Dim Display


you may have a slightly damaged power supply...although swapping the main supply chassis may solve, I have seen front panels that have an additional supply section. look on the front panel board for any TP's and probe with an O-scope. if you see a TP that may also show (+ xx V), where xx is a numerical value-may be one x only, the scope must show a straight horizontal line that is shifted vertically away from its normal (ground) position. that confirms a DC value present. then determine the DC value of the shift. Another possibility, since you invested, is to search ebay for a second unit for part swapping. look for as-is units.
