I don't think you should even bothertrying a repair. It sounds exactly like
my Apple 17" that I tossed last month. Trinitrons just never seem to repair
right. Just get a new monitor on ebay. I bought 3 (yes, three) 17"
Viewsonics for about $100 including shipping.

I just looked and there's a 17" applevision 17AV, for $10, plus shipping. A
bit smaller, but you won't need a monitor adapter nor have to buy an
outboard sound system.

Once you get something like that then keep your eyes open for a nice cheap
19" monitor with speakers. Buy a monitor adapter anyway so you can use any
monitor on your Mac.
