Hi all,
OK, I'll be honest, I registered to get help with my monitor......
A few days ago, it started flickering (and, from what I have been able to ascertain from numerous searches; this is a rather common problem. However, mine ends with a little twist...).
I discovered after about 5 minutes of searching online that the probable culprit was bad caps (so now I'm finally on the right site... hopefully).
Anyway, I found this nicely written PDF file that had 6 pages that pretty much told me to replace capacitors C110 and C111. So I ordered a few of these capacitors online, waited til they arrived and then disassembled the monitor to discover mine was different (the guide described 2 x 820uF & 25V capacitors; mine had 3 x 1000uF & 35V).
So I decided to go to my local (32 km away) electronics store and purchased 4 x Brand:- S.I., 1000uF, 35V, 105ᵒC, Low ESR capacitors; the original capacitors were Brand:- CapXon, 1000uF, 35V, 105ᵒC capacitors (I purchased 4 rather than 3 in case of the inevitable F.U.).
Whist at the electronics store, the guy who served me pointed out that the large capacitor was also bulging slightly at the top; so I purchased a replacement for that one also.
Large Capacitor
Brand of original capacitor:- CapXon, 100 uF, 450V (GL108ᵒC, C630, VENT was written on the other side of the capacitor). The replacement I purchased is shown in one of the attached photos (sorry, my eyes can't read it now that it's installed). One thing I did notice was that the replacement was rated at 400V whilst the original was rated at 450V; which has me a bit confused as to whether I was sold a suitable component........
After replacing these capacitors and reassembling the monitor; to my absolute delight (and slight amazement as I had never done this sort of work before); the monitor was working and no longer flickering!
The repair lasted for 7 minutes and then the screen went black. I could turn the monitor off, leave for 10 seconds or so and then turn it back on to have it work for another 7 minutes.
So, yeah, I've "fixed" one problem but now I have another..........
Any suggestions as to what I did wrong?
Just one last point; the replacement capacitors (except for the large one) are physically larger than the originals and 2 sit hard up against each other so I placed a "pad" of folded up insulation tape inbetween the two touching capacitors (as seen in " Smaller Caps replaced.jpg").
Thanks for taking the time to read all of this...........
