Re: Hanns-G HU196D monitor not coming on.

Hi Guys, thanks again for your time.

I think I'm going to leave the old monitor for now seeing as how its replacement is fixed and working great again. I've spent so much time on this already it would probably have made better financial sense just to have bought a new monitor.

I appreciate what you are saying about the quality of the caps and I must confess I did not recognize any of the manufactures' names on them and I can't now recall what they were. On the still dead monitor I did change all the caps on...

Re: Hanns-G HU196D monitor not coming on.

Hi Guys……well I managed to get new capacitors from the guy in the back of an old TV repair shop just 2 hundred yards from my house - go figure. Unfortunately it did not work for the monitor in question here, but I did have complete success with my replacement monitor that was starting to play up as well. I guessed I was on to a possible winner with this monitor as soon as I took it apart - see the attached photo. Out of 11 capacitors 8 were badly bulging on top and one had burst at the bottom! Hard to believe it was still working....

Re: Hanns-G HU196D monitor not coming on.

Thanks ever so guys…. I can now be confident I’m getting the right parts and that I’m heading in the right direction by changing the capacitors. Of course you are right retiredcaps and I’ll have a look in the other monitor before I order anything. Its going to be at least next week now before I can get round to that as I have already spent too much time on this over the last couple of days. I will of course come back and updated this thread with reports of how I got on.

Thanks.
Brian

Re: Hanns-G HU196D monitor not coming on.

I did manage to find my old DMM and after replacing the battery remembered that it had developed a faulty display. So I’m just going to forget about testing and go for replacing the caps. I’m out of my depth with the testing anyway and don’t really have the time or enough free brain cells to get involved at the moment.

Thanks for reminding me about the height of the caps PlainBill, I might have overlooked that important detail. When I started looking for matching caps I discovered just what a selection there...

Re: Hanns-G HU196D monitor not coming on.

Hi retiredcaps, and thanks for your comprehensive reply.

I’m afraid I’m not failure with most of the technical stuff and wouldn’t be sure about checking voltages and have no clue about PFC and ESR or ripple etc. As far as I got was that I need to match the uF value for my replacement capacitors and the voltage needs to be the same or higher. The soldering job itself is well within my capabilities.

I’m in the UK and I’ve got a few links to suppliers from other threads here. I’ll...

Hi Folks……. I think it is a fantastic site and service you have here and I hope you are rewarded with a long and happy life. From reading a few threads and doing a bit of research I think I can say I may have the symptoms of a bad-cap. My 19” Hannstar HU196D monitor began just not coming on straight away and the green light would flash and the speakers would give a short crack sound in unison (the sound speakers often make when you turn a device off) so I assumed the monitor was switching itself on and off because the screen was failing to come on. The problem got progressively worse until...
