Did this start after fitting a mod chip? if so theres a solder blob on one of the ic legs making intermitant short. i had a simular prob but it was with sound. turnd out to be a bios wire solder point nearly shorting out to the next pin, but not there when doing a ohms test..

it started from no where ... a simple mod was installed.... but it didnt start with the mod installed... it start few month after...like i said ...from nowhere...

also... its not in all games...

weird is... some real strong graphic games working just fine...

and simple games work real bad ... like in this move (im not talking about the white lines on the screen , this is from the diff refresh rates i think)

double check your wires on the mod.(one might of come lose but not off) other wise its a chip diying and not the heads of the dvd drive.. yes seen the vid and it looks like a refresh rate prob, not the white lines but the sudden blocks.. Had that prob on a geforce 4 card where the mem chips had started to fry..

im gonna remove the chip in an hour... and will clean all conections....

i hope like you said...its not a graphic chip problem...
i'll post whats going later without the chip

i have found iut where the problem come from....

its not a chip problem...

i removed the chip and tried... it was all working o.k .. i thought maybe its because i cleaned the board... maybe was something there and it fixed it ....
i then reinstall the chip... and all working o.k...
when i closed the ps2... then problem start all over...
like i sad before... the problem start from nowhere... just one day..

i opened the ps2 again... anyway..
i found out that the problem come from the uper metal board...
the one with the gray rubber...when im taking it a bit up from the board... the problem fixed... when i close it all with screws... its comeing back....
i tried lifting it a bit while puting someing under and leave it that way...now its not worst like before.. but still a problem .. if the ps2 open and im lifting it with my hand the problem gone if i press on it.. even in a mid of a working game it all start to flick again... i dont know why its happening... its the board part where the cpu is i think and the graphic chip... not sure

here is a pic of the place im lifting of the board from and its then working o.k

Whats the chip your fitting.. magic 2 will cause probs if your trying to fit in the area you marked but on the other side of the board.. I tend to fit them off the board and double side sticky tape them to the metal houseing of the hhd bay but so the drive can still be fitted.

The gray rubber is a heat sink type matterial and needs to be there.. the two silver squares below the arrow are the graphic mem ics if memory serves me.. the only other thing it might be is the wires for the chip have been pinched when you put it back together, and will now need replacing.

hi
i will say it again...
the problem is the same with a chip and without...
the problem started with a ******* from nowhere....it all worked o.k for few months... then just started...im not the owner.. im the one who trying to fix it...
the ps2 have a ******* chip atm not magic.

like i said. .. the problem is the same without the chip
if the ps2 runing when cover is open without screws...i can lift this metal plate ...when im lifting it while game is runing... the problem fixed....if i push it back...its back...if im lifting it a bit ... problem still there... but not so bad...
weird shit
hehe

theres either a dry joint developed , abit of solder on the mat, or the very bad news a crack in the motherboard.. otherwise i am out of ideas without the board in my hands

**TRABEL** · 7th January 2003

can you explain more what you said?

tell me what to look for.

thx

**dragon69** · 7th January 2003

Dry joint:- a solder joint that does not make good electrical contact. normally seen by the dullness of the solder joint. casuing probs like you have

While you have made sure the board is clean of anything the gray mat may have something on it . dout it this thoe.

Cracked motherboard :- hair line fracture that when opens up causes any tracks it cuts to brake electrical contact making probs like you have. Only way to see these is to flex the motherboard gentally and look for line that should not be there, can sometimes be seen as a scratch without flexing the board..

Hope this helps..

i will open it again... and will take a better look...
im sure its not any conection from my soldering ... as it was without the chip as well.......

also..i did clean all ic on the board with special spray and brush...

i'll look for a break in the board... but im doubt this is the prob...

i'll open and see :-)
hope i'll find anything
thx

good luck in your hunt for the prob.. the dry joint might not be from your soldering they do sometime develope.. check a round the capacitors (the sliver looking disc at the top of the pic with a black mark on and about 1 cm high).. these are the only things I can think of that might be affected by the metal shielding as well.
