Re: Asus K53SV turn on automatic
Hello i have the same problem. It started that that the laptop randomly wont work. It turns on automatic but no image.
I checked with laboratory power supply and found out that it drained only 0.07 amps. When i checked no power to cpu and chipset.
Signals from EC were missing.
I resoldered EC, now it drains 1.00 Amps but still no picture. It still turns on automatic. When i turn of, it turns on itself and turns on and off every 3 seconds.
I suspect a breakage somewhere but i cannot find it. All voltages are ok....Leave a comment:

Re: Need firmware and guide to flash Benq T903
Its not the switches and i replaced all capacitors already. The problem actually started when there was a power fluctoation. I already replaced the ic with a different one but the firmware is wrong so the power light keeps on flashing and the monitor is not turning on.Leave a comment:

Need firmware and guide to flash Benq T903
This monitor sometimes works sometimes not, if its off completely it takes a long time and many tries to switch it on. When its on you always get the input select window. It was off yesterday and seems it can't come on again.
The fault is from this ic: myson mtv312mv64
I need to reprogramm it. I need firmware for benq t903 and guide how to flash with isp. I am using willem eprom programmer.

Re: HP Pavillion G7 Capslock and Numlock Flashing
Hello its intel core i3 i reflowed the chip twice but still it does not work. there is no extra graphic chip. Btw i never have sucess with core i3 machines by reflowing, it never works for me but older machines or amd its just fine. I do reflowing a lot and most times it can work almost up to 6 months which i think is ok.Leave a comment:

Re: HP 625 no power
Use external programmer, remove the bios ic from the board and connect it to the flasher after that you solder it backLeave a comment:
