Re: Coby tftv4028 is flashing different colors
you may need the original remote control as mentioned above you could also try replacing the eeprom with a pre programmed one or failing that if you can find a exact matching mainboard if cheap enough (make sure you match all numbers from your old mainboard and get one from a tv that has the same lcd panel as yours)Comment

by STKR123As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -

by H34TORecently 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

Hello,
YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -
Have a Pioneer VSX-1021 that goes to MCACC flashing as soon as it is plugged in.
If I enter release mode, it powers on, the screen display is correct, but then it shuts down and goes back to MCACC after a few seconds. I can shut it down to standby (w/o flashing MCACC if I hit the power button as soon as release mode finishes the boot sequence).
Entering reset mode and executing a reset doesn't change this.
I am unable to enter service mode to see the error counts - Enter + Power button doesn't do anything, whether from normal standby or from MCACC flashing....-
