Hi,
I have a 15V2000 that I've been working with for a bit now. I didn't want to post right away, as I wanted to give it a shot, but I'm getting to the end of my rope.
Here's what's up so far:
Game plays blind
Spotkiller not lit
I have HV (I haven't measured it at the anode, but I know I'm getting it because when I discharge, it's there)
Blowing F600 and F700 on power up.
I was heavily concentrating on the HV board because I just thought that everything else was fine and then realized that these fuses were blown. I replaced them and the continually blow on power up. I tested all the transistors and went ahead and replaced them anyway (the U07 and U57s). Tested the diodes for each and they seem to test ok, unless the value they're throwing is wrong.
Tested various other parts and did a tube swap to rule out a yoke problem.
I don't have another chassis to throw in to test with to see if it's a problem with the HV board, but I wish I did. I don't think it's a problem with the HV board...
Oh I also replaced all the transsitors (bottle cap style) mounted to the chassis and tested for continuity with the frame (none). I tested the big caps, and have replacements, but haven't done those yet.
Any ideas? What could be blowing those on power up? They're 2 AMP fast blow fuses.
I thank you in advance.
