by MaanuDear Badcaps, i got a HP PRO X2 612 G1 with a BIOS password. Im pretty new to the whole BIOS flashing game but i was able to flash a HP Probook 2 weeks ago with help of this forum.
Now with the HP PRO X2 612 G1 i have the problem that im not 100% sure if i got the right IC and if i am doing everything right in terms of reading it.
I use the CH341A to read the BIOS. The Chip i try to flash got "771AW G GBA 609B" writen on it. I tried with the 25xxx and the 24xxx slot but i dont get a read from AsProgrammer :/
I solderd it out and put it on the 25xxx frame that...2 Photos12-09-2023, 11:14 AM -

I have an air con appliance that doesn't always start when power is applied. I have removed the small control board which is separate from and supplied by a 24v power supply (that works fine) and inspected it for any obvious failed components but can see none. I have discovered that the board will start if I wave a hair dryer over it for a few seconds. The board appears to have no temperature sensors or sensitive components on it. Can anyone suggest what the most likely candidate for a failure mode of this form.
Many thanks.

by mitsu2kHello folks, this is a last ditch effort. I thought I would seek your expertise before giving up.. I have been working on this thing for over 2 months and have gotten nowhere. Here is the issue:
Inverter powers on and immediately red GFI light comes on and inverter will not complete the initialization process.
There is no error code on the screen. I have removed most of the Y capacitors and tested to no avail.
All relays are good.
I replaced the current transducer- same problem. Checked most of the transistors and diodes and all appear good. I wish I could get my hands...11-13-2023, 07:19 PM -

by PontyPCsHi people.
I have been trying to get my head round these issues with the eMMC putting the TV in to a boot loop condition, or completely dead, when a dump of the Boot 1, Boot 2 and USERDATA partitions have been made, the MLC lifetime counter has been reset, using the original eMMC with the RPMB partition intact and the eMMC is flashed with the original dump, Netflix and a few other Apps don't work. i assume all the DHCP keys and factory programmed RPMB access Key will be contained within the original dump, and as we are re-flashing the original eMMC i would expect every thing to work....Yesterday, 10:43 AM -

[U]Pilot PD43S9HE Led TV . Panel model[/U]: See in photos
Photos tell it all really. ( added Logo image photo )
The bulge in the area before the panel Matrix .
To me it looks like a local short that heated inside.
Should I waste my time in flipping the panel , as if this issue can be repaired ?
The distribution board at this end looks ok , though I did not measure anything
What are your thoughts ?
CheersHi

by ozguvenWhen the power is turned on, a snapshot appears on the screen and it turns off. 2 red LEDs are flashing.
I disconnected the power module cable going to the main board. I threw a power on jumper with 3.3 v from outside. The relay is working and there is 12v and other voltages in the power socket.
Where else should I look? All fuses appear to be intact.āYesterday, 02:26 AM -
