i guyÂ´s iÂ´ve got a V10 silver only black screen,how can i now if the LA6508 isnÂ´t dead?
thkÂ´s in advance.
Check for continuity between ground and pin 8. If you get continuity then LA6 is blown. Also check the fuse (ps11) next to the la-chip.
If la is blown check your focus and tracking coils.
the pin 8 test is only for BA5*** chip.
ok guyÂ´s i checked the pin 8 is NOT GROUNDED, but the pin 22 IS GROUNDED.
Don't you read what Villasg said ? The PIN8 test is NOT for the LA but the BA chips. You cannot test the LA that easily. There was an article how to test the LA but I do not remember where it was. You have to do some search, but the PIN8 test was useless, so it did not help.
ok thkÂ´s both.
My problem is that iÂ´ve got black screen,i allready checked for bridges nothing found.
when i turn on my ps2,the disc strat for spin for a few seconds and than stopÂ´s.allready took out the matrix, and also the romeo fix.cleaned the board, but only black screen.
ThkÂ´s in advance.(sorry bad english).
Well where were your CDVD points soldered to ? To VIA's or to CDVD controller ? This black screen on V9/V10 machines used to happen when
1, A,B,G,I wires are soldered to VIA's and the VIA's were overheated
2, A,B,G,I wires are soldered to CDVD controller, and there is a short, solders splash or continuity between the CDVD controller legs
3, when doing the Romeo you either lifted/bridged a not needed leg aswell
4, when doing the Romeo you overheated the LA chip OR the solder were overheated and it caused a bridge under the LA chip (deep between the legs, in most cases hard to check)
5, BIOS problem (usually a short between the legs *again, in many cases it cannot be really seen or meassure* or the IC was overheated)
6, a fuse (luckily there are only a few, hehe so checking them is easy)
7, a black screen can be caused by a dead video controller/and or a dead oscillator near to the BIOS or the video controller - this is quite unbelivable at this point as the disk would boot but with no picture (except when the problem is at the BIOS IC)
My guess is either the VIA, CDVD or the LA. I repaired several boards that were overheated and the VIA points were damaged. I suggest to use desoldering braid at the via points, or if you used the cdvd then at the IC legs, (of course for a short time, as you can easily kill the IC with your soldering iron) and the cleaning of the board is recommended. It is hard to tell what your problem exactly is, as there are a thousand possible reasons, unfortunatelly that is why I hate the V9/V10 as well after the V12 they are the most unreliable things, and the symphtom that you have is just the usual daily thing that happens to these V9/V10 boards...
It wld be good if anyone out there can provide the article for checking whether LA is okay or spoilt.
ok thkÂ´s a lot uns97,i will check the viaÂ´s point and tomorrow will post the result.thkÂ´s for replying man.Guruguza.
