Question about Hannstar I-Inc TW-191D Monitor
Maybe bad caps (capacitors) you need to be familiar with high voltage(200VDC iguess, here it is 400VDC) to do anything of your own.
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).
