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

My TW191D Monitor will not power on. It was sudden and there was no indication that there was a problem developing. It happened after a power outage, but not directly after it. Can anyone tell me what they think is wrong with my monitor and maybe what I can do to fix it. The manufacturer was not helpful at all. Thanks


Answers :

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).

Dead Monitor Hi, I bought my parents an HP computer for Christmas and now, only 7 months later, the monitor stopped working. w1907 monitor. I've read some comments on here but don't understand what the solutions are saying. I don't know anything about inverters etc. Can a monitor be fixed or replaced since it's only 7 months old? I think that's an extremely short lifespan for a monitor, especially since it's used only a few times a week for short times. Thank you the monitor is dead
