Unit will not come on after power outage, fuse is ok

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 85?C version rather than a 105?C (which I've used).

Sony tv squeal

Usually out of tolerance capacitors, resistors going high, and leaky diodes in the switchmode power supply can cause a high pitched squeal from any TV. Occasionally a bad transformer winding on the same board can also cause the noise but can also be a deflection fault. Check the PSU board for any bulging or dodgy looking electrolytics first then proceed from there. If you have a multimeter, you can measure the diodes and resistors. Before going any further, and worrying about repair costs, do some simple checks first. You may end up needing a replacement PSU PCB for the model of TV you have; a refurbished board is cheaper than a new one and if you fit it yourself, you save on labour costs. Start with the power supply board and work from there.

I need power supply for VCR. Repair shop unable to obtain. Thanks, Steve

Had a look around for you at most parts places for Panasonic and couldn't find it either! Your best bet is to contact Panasonic to see if they have it. Otherwise I have seen a couple of these on E-Bay, so you could get one there - probably cheaper there than the PSU anyway. And as long as it powers up, you either have a good video or the parts for your old one!

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.

Toshiba VCR V-e41A fails to switch on . The fuse is intact. need circuit diagram to repair. please suggest
Above is a VCR Training manual, this is what is used to teach the Engineers how to troubleshoot and repair these types of units.

Usually in these units, it is either the Power Supply is faulty, or, Check the Mode Switch, these are common causes of NO GO. One MUST ALWAYS start at the PSU, as if the Voltages are NOT correct there nothing else can be.
Above is a DIY troubleshooting and repair website for the VCR.

Philps DVD Recorder/VCR

Barbara,From your description of multiple problems there is, more than likely, a circuitry problem that is causing the unit to shut down. Unfortunately, this is not an easy fix and will require a trip to the shop. Get an estimate before approving repair. In the new world of disposable electronics the cost of repair may exceed the value of the unit.
I just checked eBay and there is an identical model (Item number:300342819479) priced at a "Buy It Now" price of $44.00. So there is your answer. It would cost less to buy a replacement than to repair your unit. Like I said: "welcome to the world of disposable electronics"!!

VCR will not turn on.

Remove top cover of the VCR. Then look near the back where the plug-in and power supply is. There should be a little glass fuse. You should keep that fuse and take it to the store and replace it with same exact one. If your VCR can be self-repaired, than this is the only thing you can try.

sounds like the capacitor on the start up voltage to the drive ic in the power supply has dried up.If you never unplugged vcr before you wouldnt have noticed problem.Now since unplugged cant start up properly.It is the capacitor nearest the ic in the psu can.If you know anyone handy at electronics should be an easy job for them.
