JVC VCR remote LP20303-009 not working?

Calling all JVC experts (which I clearly am not! lol)

I have 2 JVC decks I'm trying to use the remote with one is the HR-S3900U and the other is HR-S3600U. S3600U has menu button the front so not a big deal. But the S3900U does not. So I want to access that menu. I have a remote that worked for years on both decks, then one day it just stopped. So I picked up another on eBay for a few bucks. It (erratically) worked the first day. It wouldn't work for the first few minutes, then worked steadily. Very odd behavior. Then today it wouldn't do a thing. I'm 100% sure the batteries are good. What is going on? I find it hard to believe both of these remotes are dead on both VCR's? Also for the record, the 2nd remote only worked with the S3900U that first day. It never worked with the S3600U.

Thanks in advance for your help!!!!!

If you were to dismantle the remote, odds are the mainboard has battery acid on it. It's just a dud remote. You were correct in getting the LP20303, but simply have a bad copy.

Point at your phone camera, if the LED flashes under a digital camera image then it's producing 'something'.

Or point it close to an AM radio tuned to nothing and press a button, if you get a static buzz from the radio, something is happening.

I'm here all week...

If you are lucky it could be the battery contacts that are corroded but not the PCB itself. Leaked battery stuff, provided it's from normal alkaline batteries (and not from old-style rechargeable NiCd ones which is rather toxic) can be cleaned off with something acidic like vinegar or citric acid, use gloves.

Ok I'm on the 3rd or 4th remote I've tried and it won't work with either the HR-S3900U or the HR-S3600U. I am very confused. The first remote (that I still have)worked with both just fine, and then just stopped. But now I can't find one that will work with either one. And I don't see how the receiver would die in both VCR's at the same time? Any other thoughts? Sorry it's been such a long time. Everything takes forever when you have kids lol.

What happen if you unplug the power cord of either one of your 2 vcr's ? Does the remote work flawlessly ?
