Question about Orion VR213 VHS VCR
I am having problems tuning in my VCR to the TV. I have managed to tune in each of the four terestrial chanels but it won't save them how do I get it to save the chanels?

Hello Han01, I am going to assume that you have a good RF signal coming in and that the four terrestrial channels are coming in clearly. Normally I would use a VA62 or a VA62A to inject a signal at the proper input voltage of off air RF about 1000uv down to 500uv. Injecting the signal will allow you to test if the TV can lock on to the signal and capture and store it. If it can then your issue is with the signal level coming into the TV set from the antenna. If not, then your problem is the sensitivity of your RF tunner which would indicate a possible RF input/amplifier issue. If it is the actual tuner, I would then suggest getting a OEM replacement for your tuner, I have repaired 6 tuners in my 25 years of TV experience and every time I finished the job I vowed I would never do that again. Finally one day I purchased an OEM tuner replacement and I have not repaired a tuner since (It's good academic work, but not worth the time, if time is money). If the tuner is not the problem then the issue may be the chip which stores the channel in memory. This can be checked with a multimeter or an oscilloscope (data pulses and truth tables will be used here). In any event. If you do not have any of the equipment I mentioned, and do not have electronics experience, I would suggest taking your VCR to a TV repair shop, since these measurements are very critical in the analysis of your problem.
