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.
