working on a old 820-2533 with no pictures, no backlight and no chime.
I don't know history off board but found some a little area with water damage (around u6990 replace u6990 and the capacitor straight with and cleaned area)
Still no pictures no chime no backlight.
When I remove the ram it is beeping with ram error.
I measured pin 6 on spi rom and get 0V
When I press start on the machine pin 6 gose from 0V till around 1,5V then back to 0V.
When measuring Pp3v43_g3h to ground I getting 3.05kOhm
When I try too measure all_sys_pwrgod the machine shouting off..
