HP LA2205WG weird image

Hi guys,
I have a problem with this monitor and i need your help.
Is this a bad power supply, bad mainboard or bad panel?
The panel is a LG LM220WE1.
If the monitor is powered off for 2 or 3 days, upon connecting, image appears without any issue for a few seconds only.

My measurements so far:
VGL: -5.362V
VGH: 33.12V
VGH_L: 33.12
VDD: 12.70V
VCOMC: 5.535
GVDD_E: 33V oscillating with -5.3V
GVDD_O: Same as GVDD_E
VIN: 5.112V
SCL/SDA: 3.3V

Thanks in advance...

pin1 and pin4 = 422.7 ohm

pin1 and pin8 = 000.4 ohm

Resistance to ground from B+ = (innacurate reading) droping from 2.5 Mega ohm...

Re: HP DV5-1155ep No Power

Ok, 3V and 5V are present now. Had to replace PU13.
But still no power on..
I think there must be 19v on pin24 of ISL6251A, but there is only 0.66v ???!!

Any ideas now?

Best regards

Re: Sony Vaio SVE1512R1E Bios dump needed

I used the search button before asking for this dump, and had found that thread but only one dump from those works on my laptop.
Displays image at Sony Vaio logo but then stops displaying image, altough i can hear the laptop entering Windows OS.
No image on LCD, external vga monitor and hdmi cable.

Already did a reballing with the old chip first, and then with a new one.
Same results.

Those dumps won´t work on my laptop model.....

Re: BIOS for HP CQ71-305SF

Now you need a program called "nbdmifit" to save some elements on the bios.
I will upload the program and the instructions for you later because the badcaps server is very slow for me at this time.. (Don´t know if it´s my problem or server problem)

But, does your HP stops with some error? Your OS is not loading? Or is it stuck on Bios Logo?
