An Albanian gentleman asked me to check this for him because he has lots of tape from home, and I don't have a clue about multi system VCRs. It's an Aiwa multi system VHS model HV-MX1.
It auto selects between NTSC and PAL when played back, and it has a selectable output of either.
When playing an NTSC tape, it auto selects NTSC and plays a perfect picture in color on an NTSC LCD TV via AV input. When a pre-recorded PAL tape is played, it auto selects PAL properly, but the picture on the monitor is black and white horiz bars, as if the horizontal hold was off just beyond lock. However when PAL is selected as an output (despite the monitor being NTSC), the picture appears in black and white and with a "texture" to it (like playing a component input on the composite jack).
Not sure if something is wrong with the machine or some sort of incompatibility between equipment. He said it worked years ago the last time it was tried, but that was on an RCA analog TV.
We have 2 of these vcrs at work and they will play back PAL tapes with
an NTSC output if NTSC is set as the output in the menu and if the
tape is recorded in SP mode. EP recorded PAL tapes won't play back
properly.

I talked to the owner and he again told me that this machine played his PAL tapes on an RCA 32" analog CRT TV. It was put away for a while and now he wants to play some tapes from home for his grand kids, and that's why he tried it recently.
I tried it again today and it now plays the PAL prerecorded tape with a normal, clear, and stable picture when NTSC output is selected. Unfortunately, it's in black and white but at least it's now in horiz sync. I'm thinking there might be a horiz phase adjustment somewhere I can tweak. If the horiz is right on the edge of break, it might be causing the loss of color. I tried cooling the machine down to see if I could get the horiz to drift again, but it hasn't (suspecting aging electrolytics).
Anyone have a link to a SM?
