I won my Vectrex on ebay about a week ago for $160 ,got about 5 hours out of it in 5 days, yesterday i was playing Star Trek and had just made it to level 2 when all of a sudden the monitor pooped , the picture looked kinda as if the brightness was up all the way giving the image a line from the middle of the screen to every object on the screen (normal on mine if i turned the brightness up all the way , i keep it at half brightness to save the screen normally) but whilst doing this the screen was fading darker and darker till it was just a white dot,all this happened within 10 seconds at that point i panicked and turned it off , After having about 3 heart attacks and an hour of letting it cool i decided to plug it back in and test out the damage , sound works great , no screen , no white dot... ive checked most of the solder points and they all checked totally fine on the multimeter , the fuse i think is ok but i really cant be sure as its the most bizarre spring hooked to one tiny wire type of deal 500ma 250v , pics http://tinypic.com/r/970avc/4 ,ive also checked this as it seems to be a fix for some with kind of alike problems ,Seems to be working with no breaks http://tinypic.com/r/245fqjd/4 , I really hope im not at a loss here as i just got a second controller in the mail today ,pole position hopefully tomorrow should be here and have collected about 15 games, one spare star trek cart and one extra spike id be willing to give to anyone willing to help get this going again. So So clean too. Kills me. http://tinypic.com/r/2ec3uq9/4
Thank you all for reading and or possibly helping me figure this out ahead of time , Ive heard people that have fixed these for ten years or more and have fixed thousands of them say that they've only ran across one dead monitor out of every 1000. Please Dont let this be mine...

Well I'd be looking at the monitor board in that case, best to
be careful though. Here are some links that might be of help:

Monitor Repair FAQ:
http://www.repairfaq.org/sam/monfaq.htm

Vectrex Service Manual (link is down the page):
http://www.atarihq.com/vectrex/archive.htm

The first thing is to look for swelling capacitors,
burnt/melted components, components to test with your
multimeter, all the obvious stuff on the monitor board. Past
that I can't give you much guidance, it might come down to
using an Oscilloscope to look at the circuit working, but
you're probably safer (physically) giving it to someone with
some experience at that point.

The Vectrex has a slow blow type fuse, some of which can look
prety strange. The multimeter tells all anyway.

Vectrexes? Really?! Anyway, it depends what they meant
regarding the monitor, the CRT is unlikely to have a problem,
but the Monitor circuitry is likely to be just as suspect as
any other part of the Vectrex.

Noticed this today on the website of my favourite electronics
store, does the image remind you of something?:

&imageField2.y=25&stock_no=14770

By the way, 20 for $3.00 = why they are my favourite
electronics store!

Monitor circuitry Id have no idea about, it would be sweet if i could figure it out. The vec was babied before i got it and looks so new , the crt not blown Is my highest hope right now. I really want to get this running again , in the mean time ive won another vectrex on ebay for $118 that runs to hold me over , first thing is to clean it (something i should have done to the first one, which really wasnt to dirty).
