Hi

I have a TOSHIBA RDXV60KB VCR/DVD Recorder, not been used very much, but when you switch it on all that happens is like a solenoid switching on and of noise , lights do come on at the front of the machine , have located the part that is making the switching sound ( arrowed on the picture) will try to upload a Service Manual for it, have it in a .pdf format ! .
Any help in what would cause that would be appreciated .

cheers
Spike

The manual is very comprehensive. I did find it amusing that the board is marked HOT and COLD for HI/AC and LO/DC voltage. Just what is the problem? Couple of ways to approach it and first check the power supply rectifier/output. Then go for what is wrong and trace back. Drawing do show test points and I assume test voltages (didn't get that deep into it).

Hi
Thanks for your reply , have a bit more info , it could be a Diode, D1150, but I can't find it on the drawing ! .

There are photo diagrams of the board so it should match up pretty easily. Either that or the parts list should help. Why do you think the diode is bad? Simple enough usually to desolder and test one.

Looking at the circuit that relay is Error Voltage detect. So on power up there must be some problem in the powersupply. Check diodes for shorts bulging capacitors in the power board would be a start.

Thanks Guys
Was told it is a regular problem with this model, D1150 is the problem Diode ( 1N5397B) but I just can not find it on the drawing ☹! .
Cheers and tks for your replies .
