I have done several DS55s, DS850s, DS550s. Let me know if you're still interested. Typical repair cost runs $300 - $500.

I have a video Panasonic AG-1980. Defect: When I am assisting a cassette and the key this TBC in off the image is normal and the color also. I slide the control soft-sharp and the silent image according to...


these decks are notorious for bad surface mount capacitors in the video and servo circuits. there will be quite a few that will need to be replaced. if you cant do it yourself, it will probably cost too much to repair. you will need access to an esr meter (pasive capacitor checker that checks the capacitor in circuit and the part does not have to be removed), a good soldering iron with a small tip, flux, thin solder, hemostats,solderwick blue and patients. the capacitors in question are the little round silver capacitors soldered directly to the boards. test all caps and locate caps with bad readings and mark them as bad but dont cover up the value marked on the top.the voltage is listed as a letter followed by the series of cap.(eg: 16 jhb would be a 16 mfd, j voltage rating, hb series cap) you can buy these caps cheap from digikey online. you need to be very careful when replacing the caps as if you do it wrong you will pull a trace and have to do major jumper wire work to replace the broken trace. the key to removing the bad cap is to grab them with the hemostats and squeeze, once the hemostats have a good grip of the cap start spinning the cap, dont pull just spin.you are trying to break the leads. once they break take your hot iron and wipe off what is left of the cap leads, let it cool and go back and remove remaining solder with the solderwick. clean the spot on board where cap was with anhydrous alcohol to clean any fluid that leaked out of the cap and made it bad. gently grab replacement cap with hemostats so you can hold it and apply flux to bottom of leads, place cap in its place watching polarity( black line on cap is negative and lines up with solid white side of silksceen on board or opposite the little plus on the board, if there is not a line on the cap or if there is a small "n" on the board it is a non polarized cap and direction does not matter)put a small(SMALL)amount of solder on your iron and touch it to the remaining exposed lead. if you fluxed enough and you used the correct amount of solder it should jump to the lead and leave a small shiny round solder joint. practice makes perfect and this will fix your problem. you may have to replace 40 to 50 caps maybe more, depends on how many are bad. good luck with your repair, 1980's were good decks!

The main light on the front panel went out on my 1980 desk editior. how much to repair?


The display on the AG-1980 goes dim mostly from old age - replacement of the display usually cures the problem, though you may need to replace some or all capacitors in the power supply.

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


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.

If you are seeing tape collect inside the unit, the takeup side is not functioning correctly. This may be as simple as a belt change or idler change. This is not a repair I would suggest that you start with. The alignment of the tape is critical to proper functioning. I would geuss that the "link support mech" is probably just the belt/idler assembly or it is a "mode" switch. In any case, this unit should be sent in for repair. As part of that repair, the conformance to industry standards.

Good Audio, Bad Video


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

Relace mainboard in mini dv tape deck


what symptom does it have? describe what it is/isn't doing; most of the problems I've seen with AG-DV2000s are related to either defective capacitors on the mechanism drive board or dried grease on the reel table positioning arms. I've never had to replace a main board in a 2000.

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.

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.

Playback is poor quality, tracking wont fix it and have cleaned head


Dear Iain, Do you route your Cable / Antenna through your VCR's Inputs (at rear) ? If yes, Do you find that the video of these cable /antenna channels is good? If the answer is yes again,then, in all likelihood, you are having a machine with dirty Video Heads.Did you use a 'Wet' Type Head cleaning cassette? If no, then I suggest you get one and use it. Again it is entirely possible that the Video Heads are worn out. How old is the VCR? How many tapes have you played back on it? Do you observe some black streaking along the edges of the images on the screen, which increase or decrease when u change the tracking? If yes, then it is time to get the Video Heads replaced.In India they would cost an equivalent of US$ 10-15. I do not know how much they would cost in your country, but it cannot be much more.
