Could not locate heatsink previously mentioned,only a "v" shaped slot beneath tranistor close to transformer,could you please furnish information on transistor so that I can replace it.

Could not locate heatsink, component in question is located over a small "v" slot about 1/2 inch long in front of transformer, hope this helps to locate said component.

There is a small glass fuse there as well. These units have aswitch mode power supply and the transistor that is attached to the heatsink sometimes gets shorted. This is the most likely problem. If you feel comfortable working on these and can solder, let me know and I'll provide more detailed information.

    The fuse is usually a 3.15 Amp fuse (GMA type). I need to look up the transistor.

Why does my vcr keep blowing fuses?

Always in the power supply section. Anything with a heat sink on it. Transformers, diodes all the usual suspects.
You have answered the first part of your question yourself - a short circuited device. Ohm meters are good for looking for them. The needle will act like you have touched the probes together. Watch out for capacitors that could store a high charge though. Most repair people will replace the big capacitors anyway as they are troublemakers, even if they are not the cause of the fault.

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!

VWM - 360 Model / Keeps blowing the 2A / 250 V Fuse the moment the plug goes in the outlets.

Fuses keep blowing because a semi-conductor device is acting like a piece of wire. Look in the power supply section for transistors or voltage regulators or anything like that. It might be even damaged or burned.

Last night when I went to use my VCR, I observed the display screen was dark. My VCR is a Zenith VCR Model VRM4170. I inspected the power input board and found the 1.6 amp, 250V fuse was open. I...

really not cost effective to repair...VCR's can be replaced for a cheap price!!!
open fuse >>>check your bridge...rectifier DIODES...
check your regulating IC>>>a mosfet transistor connected to a Large heat sink...maybe shorted...break out the FLUKE meter and have fun...

Dead Set

Could also mean a blown fuse in power supply. Fuse needs checking first if it keeps blowing then yes could be regulator, filter cap or rectifier diode fault

Mitsubishi VCR HS-U57 power supply questions

The closest model I have is HS-U61 it may be the same
D901,902,903 and 904 -are part of a bridge rectifier -standard B+ diodes DSA3A1 - 264P430030
D913,D914-(connected directly to R902 through transformer winding to D914) -1SS82 standard switch diode
D917- (connected to base of Q903 and D916) 1S2076 standard switch diode.
Check if they are located as described.

No power

I assume you unplugged the unit for several minutes and tried plugging it back in to reset it. Is the outlet ok? Did you try plugging something else into the same outlet and it worked?

If the cord is ok and the fuse isn't blown and the VCR is completely dead, I would say that you have a problem in the power supply section. This could be a bad transformer, rectifier or regulator module. Unfortunately you'll need to take it to be serviced.

Please let me know if I can be of further assistance to you.

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?

Vcr repair

If you have a voltmeter and some tech savvy, you could check the output voltages (voltages which run the VCR circuitry, motors, etc.). You should find a +5 volt, +12 to 14 volt, possibly a -35 volt (for the display if it has one). If these are missing, then the unit will be utterly dead. Check the fuse: If blown, check associated circuitry on the primary (line voltage) side. The fuse almost always poofs for a reason, and until the bad components are found, it will blow again, perhaps causing more component damage. The switching transistor may be shorted, plus nearby resistors/diodes/capacitors poofed/shorted/defective. In many VCRs I've worked on, a capacitor on the primary side will fail, and cause a dead condition, sometimes causing the noted transistor to short. A thorough check is highly suggested. It isn't fun to install new parts, only to have them poofed by a yet remaining problem somewhere. Common failures on the secondary side (where the voltages noted above are rectified, filtered), are the electrolytic capacitors. Common values here are 1000MFD/16 volt, 1500MFD/10Volt, 2200MFD/10volt or close. Many of the older VCRs pre-90's developed this problem.
