Anyone with an idea on how to disable this laptop onboard Ram
-
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Need to disable on board ram ...
Pls anyone share on board ram disable tool or how to disable on board ram using resistor shifting ? -
If the laptop turns on but there is no picture or constant restart, you need to disable the on-board memory.
This is how the resistors should be installed11-27-2024, 01:18 AM -
I had one blown memory chip (out of 4) the laptop would not work even with a ddr4 module.
I had the on board memory disabled though a custom bios and the laptop was working fine, problem is as soon as the bios get updated I have to do it all over again.
So I need your help on how to disabled the memory at the hardware level, I ve already removed the memory chips and the resistors/capacitors around them but it still won't work without the custom bios.
What else do I need to remove?
Schematics... -
All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
