Having problems with your Hannstar I-Inc TW-191D Monitor ?

I have a I-Inc monitor model# CY-199. The power went out and back on after a minute, the monitor was on and working when the power went out, when the power came back on the power button went blue like normal then started flashing between blue and amber. I figured i blew a capacitor so I took the back off and did not see any that were bad. Is there anything else i should be lloking for. FYI i have tried a seperate monitor on that computer and it worked. I tried this monitor on a different compute


Answers :

It would be nice if all badcaps are bulged/leaking. Changing the lamps is a pain in the ass, i will try it myself with an 191d. But i have tried first the power supply with multimeter capable of 100kHz AC 200mV range. Better if you borrow an ESR meter capable of in circuit measurement and test all condensators.

Allways discharge, disconnect from pc, switch iMonitor on and pull wall plug, push ON button for safety. My 400V capacitor is then down to 7VDC (germany 230VAC mains). Or wait for 30 min, (i am not patient enough for that).
