Hi Everyone
I am having my first serious attempt at repairing a motherboard after years of playing around with phones and Pc's but stopping at motherboards. Ive been watching many vids and blogs on the subject but have finally got one to have a go at. As Im sure you aware watching and reding are not the same as doing and despite my confidence at first its not going very well ha ha.
The laptop is HP Pavilion 14-eco0537sa. Board DAG7GMB38CO REV c. No power up at all but i have 19v at first and second Mosfet and in certain locations around the board. I have no 3.3 or 5v and am struggling to ID chips and get schematics. Could you please advise on the following Chips that i have ID,d them correctly:
WINBOND25080DVNIG = BIOS
RT3662A GOW BFG3D = Power management
INTERSIL 9238HX126HV = BQ style chip?
ITE IT66317FN 2119-BWG = HDMI
ITE IT5570VG -128 = GRAPHICS CHIP
ALC3314 L81GVH1 GL35A2 = sound
Any schematics that someone might have would be helpful. I am first trying to find out which chip should i be looking for my 3.3 and 5v first. Is it the Intersil or the RT3662A?
Tools i have are MM, bench top power, soldering equip and lots of enthusiasm.
Thanks for letting me join and any help or pointers is very much appreciated.
