An idea to get replacement capacitors EASILY !!
Still another way to make capacitor modification successfully tested !!!
The major problem with the 'ultimate capacitor modification' is (or has been..) to obtain proper capacitors. I have been thinking how to solve this problem and found a nice solution :D Look foto below:

.. it is 'an old school' Intel motherboard, socket 8. There are several purple OS-con capacitors values of 6.3 V /330 uF. Since those capacitors are SUPER when new I think that those could still be good enough as replacement capacitors... I ripped those capacitors off and measured capacitance/leakage/ESR and found those are still several times better than 'green bad capacitors ripped off from BS-card'. I think that the ESR value is far more important than capacitance => having 2-3 Os-con capacitors instead of original should make card working.
A Finnish friend contacted me to get replacement capacitors, but my supply had run off. I suggested him to test these capacitors, and he made mod using these Os-con's (Big Credits to 'Jake' :toast:). He soldered three capacitors (2 as replacement, 1 between TP's) see fotos below:

The result: Before a completely 'BS' GW6800le card (with "4 3 470 6E" capacitors) started to work just fine !

So, if somebody insists do perform 'Ultimate capacitor modification' and find it too difficult to find decent capacitors, try to look for old Mobos !! However, please note:
- Desolder carefully !
- Be sure you have the same kind of capacitors (Os-con, specifications equal or better)
- Try to test/characterize capacitors somehow i.e. those are not ruined. For instance measure capacitance/ resistance (leakage) or test how long capacitor remains charged (measure resistance and after that check voltage, should remain constant/high level for moderate period)
I need BS Help, little different to other types!
Hi,
I need BS Help, little different to other types!
Hi, I purchased an XFX GF 6800 128MB DDR DUAL DVI TV (AGP8X) with product code : PV-T40K-NDD3 secondhand from ebay, but have ended up looking at this website.
The problems are, no matter what driver I use, After I install a driver, When I boot, just as it gets to the windows login screen the screen goes black, monitor hits standby, But when I reboot , then press f8 then choose "enable vga mode" it will work (in software mode) only when any driver is installed this black screen will occur.
I see a few posts above "lenselijer" is having a similar problem to me!

soldered the purple capacitors back and i had screen again, but when it tries to boot windows xp it goes black, and its not the drivers or rivatuner, because my ti4200 works fine when i put that in the same computer. this was at stock frequency.
I have tried the card in another PC and still has same problem. I initially thought as im using dvi > vga adapters this may have caused it, but i see the BS issue seems common and obviously some design fault.
Seems to be using SVP 560 caps marked 502, svp, 560, 10 for C136, C142 & C143
47, 470, 16a for c141,
443, svp, 1500, 2.5 for c138 & c146
504, svp, 330, 16 for both c139 & c148
Anyone have any idea whats wrong?
What do you think has gone?
any help appreciated!
