Fuses blow afer power surge

After a power surge, the VCR blew the 1.6a main fuse. Replacement fuses blow as soon as the VCR is plugged into a power outlet.

I assume a diode and/or cap in the power supply has shorted. I have no schematic and am unable to troubleshoot the power supply or determine the value of some components. Any suggestions?

Re: Fuses blow afer power surge

These are switch mode power supplies and very difficult to repair. If you don't find all the blown components, they just blow up again when you try it. If that model has a separate module for the supply, you can try and order a replacement, but they usually are too expensive.
What model is it? Maybe I have a junker I can take the supply from for you?

Wont power up. i found out there there is a fuse in unit .1 where is it 2 is it something that i can fix thank u in advance.

The fuse might be in the power supply section, just follow the mains cable. If it is a simple glass type fuse and it's gone without something causing it to go then replacing it will solve the problem. However not all fuses are glass types. And the chances are that something caused the fuse to blow.

Vcr does not take in cassette, shuts down after fewseconds

Considering both the fuse and the MOV failed from the surge, there is other damage, likely to semiconductors, in the unit.
If you have a meter available, check the components in the power supply section; diodes and discrete transistors can be checked if you have some experience. Also look for standard resistors that may have been fried; sometimes they will only have a narrow burned ring around them. Visually check electrolytic capacitors, small cylindrical cases, marked with uF values and VDC and have polarity symbols on them for any signs of bulging of the tops or chemical deposits on the board & around their bases.

You didn't include make and model numbers so any closer 'guesses' aren't really possible.
Always include these and if you are lucky, a tech with direct knowledge of that specific unit may see it.

Unit dead after a power outage replaced fuse blew fuse again even with power out of unit can i just get a new power supply?

Below is a link to a list of replacement parts for this unit.

The replacement power supply is $61.00 so probably not viable. 233160 CIRCUIT, POWER SUPPL [E3]

Depending on your technical ability if you could find which components have been damaged that are causing the fuse to blow it could be a very cheap fix.

If you require and further assistance then maybe you could post some pictures of the power supply PCB as I may be able to identify which components are damaged.

Please leave feedback

Panasonic PV-4664 VR wont't power on. Replaced 1.6A input fuse and fuse blows immendiately when power supply is both installed and removed from the unit. Appears the power supply has a problem.

Fuses blow like that when a semi-conductor has shorted and acting like a piece of wire. Transistors diodes etc will show up quick with a Ohm meter, has it will be just like you have touched the probes together!

Even though my M-635 was plugged into a surge protector, the electrician failed to check when installing a new breaker box thus burning out the unit. Is this a simple fix with perhaps an internal fuse and...

Most of the time VCRs have an internal fuse clipped in to the input line path very near the power cord inlet. it usually is a BUSS type fuse of 4-5 Amp protection. The top of the VCR can be removed by removing 4 side screws (two per side) and the top lifted off. The fuse should be visable. Replace it with a like fuse. Generally a schematic is glued onto the underside of the top and you can see a note of the size. A trip to Radio Shack should complete the replacement and re-assemble the top.

Lightning strike Vcr keeps blowing fuses

Fuses blow when there is an overload. Overloads in turn are caused by a semi-condutor device that is acting like it was just a piece of wire. In this case look around the power supply and look out for burnt or damaged parts.

I have a panasonic vcr. Model # pv-v4022

There is an SMPS unit that powers the set. You could have a failed driverr in this section. check out the input side for short in capacitors, bridge rectifier,SM driver or a mains protector. It will easy to identify by having a continuity tester for identifying the short. replace with the same type. good luck

really not cost effective to repair...VCR's can be replaced for a cheap price!!!

Sony SLV-690HF (VCR), dead

It is the electrolytic capacitors on the power supply board gone bad. It is fairly simple to remove the board. Look at it this way. Even if you break it taking it out, you would have thrown away the vcr anyway. I simply experimented with mine and it payed off. I just replaced mine in the exact same model vcr you have(slv-690hf). The vcr would not power up. I replaced c202, c207, c109, and c208 and it works perfect again. They are the smallest ones. I'm pretty sure it was only one that was bad, but i replaced four of them just to make sure i got the bad one. You cannot tell by looking at them that they are bad. I just searched the internet and read where it's usually the smallest electrolytic capacitors on the power supply board in sony vcrs, that usually go bad. Sure enough, that was the problem. It is fairly simple to take the board out and do it, if you have time, patience, a little bit of know how, and a soldering iron. I used some capacitors from radio shack and some out of an old stereo crossover i had that did'nt work for the replacements. The capacitors from radio shack have a wire coming out of each end instead of both coming out of the same end. I just simply bent one wire over the top to make it work and cut them the same leangth. Be sure you use the same uf and voltage for the replacements.
