I have like 30 of these.....and only one was actually not working to the point I just parted it out. They are too simple to be crap for what they cost. A few actually have really exceptional little pictures. The only problem some of these have is about half of them will have IF buzz to some degree. The design that looks like a "space helmet" (GPX or somesuch)...WOULD deffinately qualify as CRAP, but still make okay parts sets.
Any broken one....has been dropped or abused. If you are getting sweep by just pushing on the vertical hold pot....you know where to start. That pot is bad, or it got pushed on and the traces are broken under it.
It's not gonna be that big jungle chip. If it is....PARTS set, but I've NOT seen one with a bad jungle chip yet (almost all of them CD5151CP). A few smaller ones I have (Magnavox Shadow, Rhapsody,etc...with the 4.5" CRT)...all have the AN5151N. I've not seen ANY of these sets have a bad chip yet.
Just get out your GOOD eyes...bright lights and put your meter on the "diode checker/beep" setting and you are gonna find some problem on the board.
One of my "sub collections" is about 25 of these...almost all identical (different colors) and hardly any of them "dead" when I got them. Any that were, were quite EASY to figure out....so dunno what these guys find so satisfying about bashing these little sets. CHEAP...and they work, and some lucky ones can be dialed in to have REALLY good pictures and don't have that lousy IF buzz. My favorite ones even have A/V inputs and make pretty good workbench "test" sets for working on VCRs, old Atari computers and stuff.
