TV VCR Combo	Can't Post

VCR/ TV Combo GE Model 19TVR60, Serial B48415107

The pin on the lower eject lever (that goes into the bottom of the eject/ play control wheel) was broken. I am on a lighthouse so my tools and access to parts are near to nil. I removed the lever. I manufactured a new pin. I drilled and JB Welded the new pin in place. Upon reassembly the mechanical repair is a success, but now the TV is not working. When I plug the unit into the wall I hear a slight audio pop from the speaker and the VCR energizes, and I hear a relay snap but the tube does not energize. It was working fine before the mechanical repair. I have given it a visual/sniff test, and I don't see anything wrong or any hookups left undone. Where do I start to identify the cause?

Ok I dont know the model but the usual reason for this is the timing is incorrect. There is usually some form of mode switch which tells the micro the position the unit is in IE tape loads then arms pull out as heads spin. If this is not correct, what happens is the micro gets confused and switches the thing off. So look for timing marks on wheels, they usually all align with the tape out. We have one unit here where if a belt slips at startup the TV cuts out.

Which wheels am I looking at? Will I have to take the main control wheel out again or which other wheels do I focus on? Thanks a bunch.

It looks like the timing is right. I found notches and marks. Will there be more than one position that the big white control wheel will mesh with the pins underneath? I pulled it off again and it looks like there is no choice as to how it aligns. The timing notch between the white wheel and the wee wheel above it seems like it will only fit one way too. I can't see any other finer tuning. Is there anything you can tell me here? It sure sounded logical what you were saying about the timing but I can't see how to do it other than how I have.

I guess the thing isn't going to work for me. I checked the circuit boards for cracks, burned and broken components, there is only 1 fuse that checked out to be OK. It still looks to be plugged up correctly. I made sure the lever pin repair was all correct in alignment. The timing I still think is done correctly. The TV just isn't firing up. There must be another issue that I caused when I was handling the unit during the repair. I hate to say it but I may have to accept defeat with this one Pirate

I say thanks a bunch for all your help Smile
