What does error code p1 indicate?


The controller that is still alive in the unit is telling you there is a power supply line missing or not to correct voltage. Get the service manual and follow the troubleshooting block diagram.
Checking the power supply voltages is the first thing a Technician will do. One one is discovered missing then it is a job to restore that. In older units it would be a cap, regulator or transistor. In newer unit with switch power supplies they are more complicated and often fail due to puffed caps and surge damage to solid state parts.

Can anyone supply me with the common commercial type number, JEDEC number, for the power supply output transistor in the Sharp VC-H982U video cassette recorder?


Type "Sharpe VC-H982U Service Manual" into Google and you will see a free PDF of it. That should tell you the number!

SONY DHR-1000NP : Problem : No power Already replaced some components in shielded part of power supply : Replaced big capacitors (1500 and 2200 and 680 mico farad) R115 and FET Q101 will always...


I have just fixed one of these. The problem was C104 inside the metal shielded section of the PSU. It's a 2.2uF 50V capacitor. Sony used an 85degC version rather than a 105degC (which I've used). Fortunately, no other components were damaged.

Panasonic AG-DS550 VCR shuts itself down about 2 seconds after switched on. No error code appears in that brief interval. Toggling the power switch immediately is ineffective, but after waiting a while,...


This is a typical symptom of a power supply failure. There are some self-checks performed at power-up that are not completing correctly. Were there any symptoms before the complete failure? Often, the units start to behave strangely before complete shutdown. The power supply failure is tied to defective capacitors in most cases. These supplies are what are called "switch-mode" supplies and must oscillate to work. Defective caps will either not provide the kikcker to start the oscillation or prevent the oscillation completely. While there are other causes, this is the most common. AG units are professional decks and should be serviced by authorized service centers.

Hope this helps,
Dan

I m looking for a jvc br s800u svhs power supply, and a service manual,


I have a spare BR-S500U power supply which is identical to the 800. It is in perfect working order, you can have it for $45 including shipping. I can also send you a download of the service manual minus the Electrical Alignment section - but it has all schematics, parts lists and mechanism particulars. You can e-mail me at BarryMusicTeach@aol.com

Noisy video on tuner input


Well, if replacing the tuner did not solve it, the next likely culprit is the power supply. Does it look OK on A/V cable input? You didn't say what brand this is but all the older Matshushita made VCRs (panasonic, sylvania, quasar, magnavox ond others) have power supplies that fail often in this manner spewing out noise that interferes with the video signals. Some of us know how to repair the supplies as they are usually not available for replacement.
