Re: Sanyo RFWZV475F DVD Recorder/VCR Combo Turning off when loading tape
So i made a little bit of progress, I got it to actually play a tape without turning off. What i did was engage the capstan to the pinch roller manually by pulling the loading belt till it fully engaged and then i moved the roller well it was off. I saw someone do this and it fixed his vcr on accident were i got the idea to begin with.
But now it seems to me that it may be a bearing in the capstan motor thats messed up
Here are some videos of what its doing. All the noise is coming from...

Re: Sanyo RFWZV475F DVD Recorder/VCR Combo Turning off when loading tape
Only difference from the first video and second video was time. it sat for two years then when i plugged it in thats what it did last week. This is why i am lost on what to do at this point. I am ordering the rest of the caps to finish off the rest of the power board just in case it is a slight chance that it may be due to the caps i missed. checking voltages and connections would be my next step i guess. these things are built like junk all the wiring is junky soldered down flimsy ZIF ribbon...Leave a comment:

Yeah i got the timing aligned. It was doing this exact behavior before i even touched it. Yeah the sound is not coming from the power supply, I wish it was then id probably have had this sorted lol!
Thanks for the suggestions though! appreciate it!...Leave a comment:

So i reopened it up and re cleaned the encoder chip just make sure! this time i cleaned it with some contact cleaner. Still no luck. It seems to power off as soon as the arms move to feed the tape onto the hub. Before it even tries to play the tape.Leave a comment:

I am not actually sure what "SMP" means, I mostly dabble in fixing video game units and computers. So allot of this is new to me sorry for dumb questions. That sound is definitely coming from where the tape spools up around the drum if that helps. I'll also try your suggestion with covering up the sensor....Leave a comment:

Sanyo RFWZV475F DVD Recorder/VCR Combo Turning off when loading tape

I got busy during this time and it has just sat in my room for two years and now i've been trying to get around fixing it. Well now it wont even play the tape and just powers off upon loading the tape here it is at its current state

I am pretty much stuck at this point on what to do. I took it apart and cleaned the encoder mode switch! Which did nothing. So...Last edited by Bangulo; 06-05-2020, 09:39 AM. -

How do your porperly test inverter transformer.
is there anywhere that shows you how to test a transformer on an inverter board? I know you use the ohm setting, but what pins do i test exactly and what i am looking for?
Thanks in advanced. -

Re: mlk386x power supply and cap data sheets.
I know they are written on the Cap, But you really can't look on the cap from the website, it just shows a generic picture. my question is how do you identify it from the data sheet?...Leave a comment:

mlk386x power supply and cap data sheets.
So i have this MLK386x Power supply that has busted caps all around. My question is when looking at the data to order replacement caps. how do you know what ones are rated for 105 C
Two of these huge samxon 100uf 450v or blown from the back. these caps are pretty huge. Would this be sufficient?
