ps1 one chip problem

i just installed a one chip and get this problem http://www.youtube.com/watch?v=ihpLnvSJ1-0

but all games work fine imports back ups with out messed up screen its just the boot up screen where the problem is

 

remove the chip and re test.
if works then you had a short.

 

i tested this on my tv i use pc on and it shows it this way but there is 1 or 2 errors in it

could be because the tv are lcds

 

i just installed other one chip in other ps1 and same

 

just got my tv settings up and the boot screen is 4,43 60 hz and when game pal loads it 50 hz

but shouldnt the boot screen be 50hz because itz pal ps1

 

if i set tv to pal itz black and white with out messed up boot up but if i set to ntsc 4,43 it color and perfect but then when i put i pal game in itz black and white and im useing a rgb scat just tryed the color fix and change it 60hz pal but itz messed up doing my nut time for the big hammer

 

It could be your tv isn't switching to rgb mode for some reason. As far as I understand rgb doesn't use ntsc or pal color, any options or fixes specific to that should do nothing.

 

Certainly sounds like the cable isnt RGB or the switching signal pin isnt connected correctly.

Open the scart end and post pictures.

http://tinypic.com/r/izuvwo/5 there is a pin messing out of scat cable

 

looks like pin 16 has no connection, which means your tv wont go into RGB mode (so it will be composite).


Need to solder a 180ohm resistor between pin 8 and pin 16 to fix it

 

can u tell me where i can buy 1 from a proper rgb cable going to send a seller a message on ebay saying u have had my pants down

 

its an rgb cable, its just missing the resistor. add it and it will work

 

sorry to be a pain im going to have a go but not clue what im looking for i searched maplin and come up nothing can u link to right thing on maplin so i can going and get 1 2mo

 

you're no pain for no one.
we here to help !

Im an expert at ps1 chips, I also make (program) them for PIC12F629 and PIC12C508a .
You got the OneChip huh? Pretty much the best in my eyes !

What you get there is a problem with the chipcode itself (wrong programmed) or you haven't soldered it in correctly.
Please tell me which SCPH Model of PS1 and which PIC Model (the Chip) you are using and I provide you with the schematics.

btw
OneChip was the best Chip for SCPH-102 Playstations (Ps1 Slim).
But watchout, there are differend motherboard revisions and thus the solderpoints are not the same !

kind regards

SCPH-102 motherboard is pm41 PIC12C509

 

first, being able to program a pic chip doesnt make you an expert. Second, it also doesnt mean you "make" them.

Third, what you posted is incorrect. its a compatibility issue with his TV and the video mode over composite. The menu screen is in 480i, where as the games are in 240p - which is why it works during game and not in the menu. RGB might sort it out and he just needs to solder in a 180ohm resistor to correct the incorrectly wired cable from ebay.

forth, he got the chip from me and there is nothing wrong with the chip code.

 

never was thinkin the mod chip because i seen ur user name all over internet and always read good things
