Hey all, new to the forum and very new to electronics repair, but I like to get deeper into it! I have some questions and hoping someone can point me in the right direction.
I bought a Sanyo Betamax (Betacord according to Sanyo) VCR that I bought off ebay, broken, as a project to fix. I finally got it today and dove nose deep into it, so when plugged in the clock flashes like it should, but when the power button is depressed nothing happens, no light, no clicks, no nothing, when pushing all the buttons, nothing happens, the only thing is when you push the timer button, so the unit will record on timer, the light comes on and the channel selector buttons light up when depressed, but still no power light when depressed.
My best guess was something was up with the power supply, since I would think it's highly unlikely that all the motors and everything was just dead. I noticed the power supply had some capacitors that looked like they had leaked but after closer look it's adhesive but it made a giant mess and had touched some connectors and I'm thinking as it aged, it caused a short. There is also an area that looks like it had gotten really hot at one point, I removed the power supply and removed some capacitors and found one with a bulge and leak at the bottom. I ordered some new capacitors because I figure I might as well replace them all.. There are some other components I'd like to replace, but I don't know what they're called or how to know what the specs on it are.. I feel certain that this power supply is the issue, does it sound like an issue that a bad or possibly few bad capacitors could cause or is there more to the situation here? Including some pics.. Thanks all!
