I've own a Sony Multiscan 420gs. I love this monitor. When I first
got it, it would get bright make a click noise, shutdown for a brief
moment and back on without any problems for about 10 minutes. Now
after three years later the problem started up again. I've heard and
read about loose solder joints near the flyback. Adjusting the g2
voltage. I will say I have joined the 15000 Volt club and have gotten
nailed by a flybacks kick... Has anyone had or seen a simular problem.
I do know how to fix stuff like arcade monitors ie G07's WG's and so
forth. This Sony is a little complex.
