Hello All

on the moment i have a ps3 60gb
the ps3 has a ylod

i searched a lot of information and read a lot of information.

and i did some repairs to the ps3, all repairs failed.

now before i go further i need some info,

When i take out everything from the ps3,
so i have only a ps3 mainboard ,powersupply and switc on/off board.
when the ps3 is 100% healthy will it boot?

so my question is:
will the ps3 ylod when it has not all hardware inside it?
will the ps3 boot with a defective powersupply,
when the power supply is defective, will it instant blink red or wil it blink green,yellow,red?

i did this:
ps3 full installed ylod
ps3 installed without harddrive ylod
ps3 installed without blue ray drive ylod
ps3 installed without bluetooth board ylod
ps3 installed without antenne ylod
ps3 installed without card reader ylod
ps3 installed with only mainboard and power supply ylod

so everything gives me a ylod
i only have one power supply , so maybe the power supply is defective

i also found out that a component ps6001 is missing un the under side of the mainboard?
can this cause ylod?



the xbox is easier to fix , because it has a secondary error code and post codes,
the ps3 hasnt , so it is very difficult to now what is the problem.
just reflow isnt the key with my board

Can somebody tell me this , please
any help is appreciated

with Regards
