Question about RCA VR634HF VHS VCR
Hi there. I have a VR634HF that I got from a relative who said they were having problems with it. I have found that it seems to be fully functional so far but it has the following symptoms: I ran through the initial setup the first time I turned it on and entered my Postal Code and setup the time zone and DST settings and all the other stuff. After the initial DOWN LOAD of information the next time I turned it on, it said it found 7 possible channel lineups for my postal code and asked me to pick which one it was. Then it asked me to turn off the VCR so it could download more info. I thought this seemed reasonable and I've left it overnight doing the download thing but now EVERY time I turn the VCR on it makes me pick from one of the 7 channel lineup choices and requests that I turn it off. Why is it doing this and can I fix it somehow?
This may indicate a problem with the persistant memory of the chip that holds the settings information. This might be caused by a capacitor that is not holding proper voltage during the setup phase or some defect in the memory itself. I would suggest getting a schematic of the device and using a multimeter check the pinout voltage levels of the section that sets and stores the settings, and the associated memory. If you do not have electronics experience I would suggest that you take the unit to a qualified TV repair shop in your area. Thank you, Shuttle83
