Re: PM_I_hpc_s mv_mb_v3
im using hp_g62_compaq_cq62_foxconn_star_federer_rev_1.0_sch , cheked EC bios there is no voltage there only on sprom , for what i can manage and understand after cheking schematic is that there is some anomaly on s3 state , since some os the voltages that shouldbe present are not there, therefor kb will not work properly
im now trying to find out why i dont get 5 volts on main dc dc , and since i dont have that voltage i also dont get 5Val on the tsp51117 (1.5v ddr3 and outher smal voltages ) cheked that PQ762 should have on pin 3 voltage there due to RUN_on_load therefore i can't get as well any voltage for +3S , since i dont have this voltage i also can't have VCC on kb controler (should be +3S and its 0)Comment

Re: PM_I_hpc_s mv_mb_v3
Check RSMRST# if 3.3v is present.
But the lack of 5v is also a concern. You must fix this first.Last edited by whaldsz; 01-21-2014, 07:07 AM.Comment

Re: PM_I_hpc_s mv_mb_v3
rsmrst = 3.30 volts .
not having 5 volts is what is driving me nuts , could this be like powersaver issue ? since there is no short on the god dam line rail ....Comment

Re: PM_I_hpc_s mv_mb_v3
guys mine is working but there is no +VDD_CORE voltage on my motherboard, so no power at GPU chip, what is possibly causing that ? any help will be appreciated.Last edited by tomodachi; 02-10-2014, 02:14 AM.Comment

So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0. I already tried two CH341A, already did the 3.3v fix mod, using AsProgrammer, NeoProgrammer, Colibri, and CH341A 1.29. But the problem still occurred. What I did wrong here? Can anyone help me? Thanks in advance. Here is the log in Colibri :

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
Hi,
Found an Funai 32FL553P/10 TV on sale for cheap listed as broken, so I decided to give a shot at reparing this.
State I got it in:
Squealing from the PSU
After logo I get a blank screen
After 10 seconds of having a blank display w/ backlight the TV dies
Give it 7-10ish seconds again and it starts to bootloop.
What I did so far:
Replaced all the caps on the PSU (apart from primaries, they were fine and none at hand)
Checked all voltage rails:
5VSB - 4.8V
AMP+13V - 14.4V
13V - 12.98V (in manual 12V)... -
I've got a Hanns.G Hi221 Monitor that works for a moment and then the display goes off but the power LED indicator remains on. If you power it off and back on again it does the same thing, it comes on and then the display goes blank. From a cold start it takes 10 seconds or so before the display goes blank but if you turn it off and then back on again after it already being on it goes blank a lot quicker so I'm assuming something is getting hot which is causing the display to go off.
I've uploaded a video of it happening on YouTube:

Hi all, I’ve got a problem I hope someone can help me fixi.
I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...01-11-2025, 03:18 PM
