Hello there I have a Zbook 17 g2 with la-b391p
I lost the original bios.bin
I did install stupidly only once the main bios-chip backward then I changed the bios-chip with a new one
I don't know what is my me-version
And I don't know if I haven't DMI in bios .bin it brings failure or not?
I have only EC original .bin
I tried some bois files but after some blinking led's it goes on high-speed fan and no display
before my manipulation, it was working very well.
I don't know if I damaged some parts like PCH or it is just the bios has a problem

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.

Hi everyone, I hope someone can help me solve my problem, I have the case of a legion t5 where I have installed an asus tuf gamig a520m-plus motherboard, the audio connection cable on the case is an F_audio connector with 14 PIN , on my new motherboard the connector is a 10-pin AAFP, I saw that there are adapters on sale but at the moment I have no way of having them available in a short time, I made several attempts and managed to listen from the front headphones, only that there are some problems, the headphones are only detected if the microphone is connected, I definitely got confused with...12-08-2023, 12:06 PM

Hi!! I have been given this old TV set.
When I hit the power button, the BL (as you know this is a CFL backlight) turns on, video works fine as I can see the LG logo show off, but the backlight starts going on-off for 3 times, when it gives up and turns completly off
This set has a inverter board on the top right corner. This inverter (or the tubes, I don't really know) buzzes very loudly during the second that the BL stays ON. I have posted a video, turn your volume UP!

I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
Since then, This AC/DC adaptor have been out of order.
But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
And Is there any possibility that it will suddenly explode as well as to be out...12-03-2023, 04:40 AM -
I have just realized that my meter is off, when I measure the car's battery, and I can't imagine how that happened.
I also have a 87, and when I doubled checked the voltage, the 87 was showing 3.5V higher, than the 189. Most likely the 189 is off.
Where should I start with the 189?
Switched leads between the two meters, but nothing has changed.
I have not opened it yet.
Any help would be appreciated....11-27-2023, 10:50 PM -
When 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.Yesterday, 02:26 AM

LG 39ln575s - power ON, backlight ON but no screen.
I checked TCon board V390HJ1-CE1 and VCL -8V, VCH 30.2V.
Display is HC390DUN. With both strip is backlight only - nothing on the screen.
If I put 1st strip off, I see 50% black 50% white. If I put 2nd strip off, see some lines vertical/horizontal with pink color (probably color of LG logo) and after that, white on thle left corner.
The IC chip CM501 (probably booster for VCL and VCH is hot - after 1 minute is not possible to put finger for more than half second.. So I think it has got about 70C. Is it normal?...Today, 11:15 AM -

Hi 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 -
