Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...06-17-2025, 07:17 AM

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.

I believe Chip 2 is BIN is the main one as it contained the Windows product key, marked with XXXXX for now.
SN: PF3G1REP
MODEL: 20KW-00J1AU
PROBLEM: Turns on blank screen, charging circuitry motherboard looks good. I have tried another firmware here - but resulted in 5V will not go to 20v due to different PD firmware I believe - using the current firmware it does go to 20V.
Requesting a firmware clean/BIOS region cleaned. Here is output from ME Analyzer:

I there!
I have this TV set that doesn't even light up the st by led. I fully checked the PS board and this one is fine, it provides 8.9V when Stdby and 13V when ON (forces by DRV_ON pin according to service document)
So I checked the main board and it is not able to even light up the stdby led and of course it won't obbey to ON button or remote signals
I checked all caps on board, none of them is shorted. I took some voltages at those caps, some of them have 8.9v on one side, some don't have any voltage. I see some coils and smalls IC's near banks of SMD... -
Hello my friends!
I have a question that I think you can answer and help me with!
I have a faulty main board from an led TV. And I found the same part number board and design but is from a 43" TV and I want to use it on a 65". On its stickers , all are the same except the wattage for the LEDs backlight, both state different watts and LED Voltages!
So I presume that the backlight inverter section from the replacement board has lower wattage then the original one, am I right?
My concern is that the board won't draw enough voltage to the bac...
