post #1 of 2
Thread Starter 
Hi all, noob here, im sorry if ive posted in the wrong section but im in need of some help, my sony gdm-fw900 crt monitor stopped working on me, the picture just went off, no bang no smoke just no picture, when i turn it on there is NO hv start up, the static thing that has to happen, and when i have the pc connected the orange lights blinks repeatedly and thats about it, if i remove one of the wires from i think its the d board that has the flyback on it i get a normal start up with degausse with the normal sounding relay click but no picture, i have some knowledge of looking inside the unit and i have a basic DMM i really dont want to throw this in the bin because its a rare monitor to come by thankyou.

ps, the flyback is making the normal sound as if its working, all 3 cathode heaters are on fine.

Never toss a Sony GDM in the dump. Sony keeps a large assortment of parts in stock for those monitors and they are like a rare Mercedes gullwing (mb will always have parts for them for eternity) and are easily repaired.
