P5PE-VM question ?

Re: P5PE-VM question ?

CLOCK LED is very dim......there's no CLOCK ??

Re: P5PE-VM question ?

The clock generator chip is :
CLK865J02FLF....I can't find datasheet for it...can you ?

[bianchi77]

Re: P5PE-VM question ?

any clues guys ?

Re: P5PE-VM question ?

Is the crystal ok ?

[bianchi77]

Re: P5PE-VM question ?

Yes the crystal is ok, I've check it on the scope....
Anything else do you reckon ?

Re: P5PE-VM question ?

I measured the voltage around CPU it's 1.37V for 3 pairs of FET...are they normal or one of them faulty ?

The CPU is Celeron D 346 ...

Re: P5PE-VM question ?

I reckon it's normal...

Can I check the clock of the processor ? which pin is it ?

I can't find CLK865J02FLF datasheet....must be somewhere there...oo...trouble..

Re: P5PE-VM question ?

I've been looking at:


but on PCB...it's not easy to get it....since it's BGA style soldered...and LGA775 socket is too fragile to measure directly....

Re: P5PE-VM question ?

I checked the voltage on positive side of CMOS battery...(without the battery ) ....abit strange....the value is up and down .....??

[bianchi77]

Re: P5PE-VM question ?

I got 0 - 4 ohm from every FET near the CPU to GND....is that allright or abnormal ?

[bianchi77]

Re: P5PE-VM question ?

FET ( source pin )

[bianchi77]

Re: P5PE-VM question ?

3 FETs got 0.000V for diode test for DMM ?? faulty ? D - S test drain to negative probe , S to positive probe...in circuit test..

Re: P5PE-VM question ?

Do you think those tilting capacitors are bad ?

[bianchi77]

Re: P5PE-VM question ?

I'll check 32KHz crystal as well....may be it's faulty ?

[bianchi77]

Re: P5PE-VM question ?

It was long beep, short beep, short beep....time when I changed the crystal...but when I shut it off...it's showing 0000 again in POST diagnostic...
I tried pushing abit on southbridge chip and it's showing D3D3 on post diagnostic....
I guess I got bad join on southbridge...

Reflow do you reckon ?

Re: P5PE-VM question ?

Was it successful ?

[bianchi77]

Re: P5PE-VM question ?

only one time working with new crystal, beep beep beep....I recycled the power....
and it returned to 0000 again....

and I can't see 32768 Hz on any pins of the crystal...is my crystal faulty again ?
how can I test a crystal ?
Can I use this one for replacing it ?

Re: P5PE-VM question ?

Post #25. The same way you tested that crystal.
I test mine with one of these. http://www.aliexpress.com/item/DIY-K...413364646.html

Re: P5PE-VM question ?

I checked the voltage of FET near the CPU with scope....on Drain it's 40V and on Source 18V...frequency = 110KHz

Interesting, how can we use it ? where can we put our crystal ?
