I just mentioned that my laptop keeps reinstalling Dolby Access at random. The Internet seems convinced that this program does nothing, but there is an audio control panel inside it with some "enhancements" (as I mentioned here) and the latest version of the software doesn't seem to let you completely disable the bullshit like the old version could. Does anyone here know how to prevent Windows 10 from reinstalling the built-in "apps" after I uninstall them?
Before some troll tells me to switch to Linux, the audio under Linux on this laptop is actually worse (at... -
Hi all,
I got an old Samsung 225MW TV with BN41-00825 motherboard.
Since the TV has a buzzer when it starts it makes a beep. The main problem is that the TV goes in a sort of bootloop and beeps every 2-3 seconds.
So I attached the VGA UART cable and read the debug data using a RT809H programmer:
According to the Service Manual all the voltages looks good, so I made a backup of the internal flash and all the EEPROMs (1 Settings + 3 EDID) and cleaned the EEPROM.
Now the TV boots but it's stuck on VGA. If I try to change the source it goes to TV, restarts... -
Hi
I have an 820-3332 that chimes, has fan spin and has disk activity (see indicator light on external drive flashing) but nothing appears on either internal or external display.
U8900 already re-soldered twice with no improvement.
For the reasons below, I'm pretty sure the GPU and/or Graphics MUX is fried but since the board has signs of life, I would appreciate any guidance that can be offered before I throw the board into the parts bin.
First the bad news: There was one spot of corrosion that had connected 12V8 at C8925-1 (PPVIN_S5_HS_GPU_ISNS... -
Hello,
I've repaired a few laptops in my life but this time my own laptop died😂.
Funny enough this one is a bit tough on me.
It doesn't turn on (most of the time).
Model: Lenovo y520-15ikbm (NM-391).
The only way to make it turn on is:
1) unplug battery + charger + rtc (seems irrelevant)
2) wait a minute
3) plug battery/charger in
4) on charger plugin, laptop turns on by itself. On battery plugin you have to press power button. Sometimes nothing happens and you have to try again.
5) when it turns on it also displays POST... -
Hi!!
Yesterday I was installing a new Wifi thermostat for my domestic gas water heater model Vaillant 242/2-3, and accidentlly one wire from mains touched one wire from the thermostat output contacts. This shut off the heater so I finished installing the thermostat and then went out to check the heater
I found one fuse blown (T2 250V). Replaced it with another equivalent fuse and it blew right away. I measured L-N in mains input and I sometimes got 4K but sometimes, not sure why, I got 100 Ohm...
At a certain point, moving stuff around, I put all wires back in place and...
