Any hope for my Mitsubishi?

Apr 11, 2005 5 Replies

My 19" Mitsubushi Diamondtron NF DPRO 920 monitor has developed a hardware fault, and is unfortunately outside its warranty. Before I reach for my credit card, I thought I'd seek advice here on the prospects of fixing it myself.



It occasionally suddenly switches itself off , and then repeatedly switches on and off. I hear its internal relay opening and closing. And, as a variation on that, sometimes I've found it off in the morning (but not cycling - although for all I know it may have been doing so before finally switching off for good).



At a quick glance, I'm darned if I can even see how to get into it!

It's probably something pretty simple, either a cracked solder joint or a bad electrolytic capacitor. Haven't tried opening that brand but often they have hidden catches, you just have to mess with it carefully or hopefully someone else here can tell you exactly how to open it.

No one with any knowhow on getting into and servicing these please?

Terry, some monitors require a tool to unhook the case interlocks. Often can be found a slight crevice or line between the cover and body, the locks are situated in the little slots that can be seen in it. Often the swivel stand must be removed to access hidden screws. Some cases are more frustrating than others but they can all be opened with sufficient patience. Only use the TNT solution as a last resort.

Thanks, I'll take a closer look.

I've now bought a replacement 19" CRT, but it goes against the grain to dump it because of this intermittent fault. Anyway, there may even be a few bits and pieces inside to add to my 25-year hoard.
