Palit RTX 2080 Super Jetstream Mats/Mods help

by Maxim Bojko

Hello,

I have a RTX 2080 that is broken, but interesting thing is that the card works how it should work, but when playing the card crashes, black screen fans go to 100% and nothing happens anymore. I changed thermal paste because I thought it was overheating, but no. So I checked with gpu z and here is what I had.

After a while a dude I got friends with told me to underclock the gpu via msi afterburner. First to underclock the core speed by 200 then open the chart for the mhz and voltage and said that I should change the mhz at 0,9v to 1900mhz. Since then I doesn't crash...

hitachi 75hl16t64u - not responding to remote control

by dfear

I have a hitachi 75hl16t64u tv in for repair and it is driving me crazy.
It came in for a power issue which I have finally resolved by replacing the power supply.

The current issue is that the TV does not respond to the remote control. I have replaced the IR sensor board with a used one but the fault persists.

Anyone have a clue how to fix TV?

FYI: I have checked the remote work s by pointing it at my camera on my phone....

Hello folks,

I have a Thinkpad L590, motherboard FL590 NM-B931.
According to the owner, 2 power supplies were connected to the two USB-C ports at the same time...

The battery is charging and the power button lights up when you press it. However, the screen remains dark. An external monitor also didn't work.

In addition, the charging LED next to the USB-C port also lights up orange when no battery is installed... There are 12.1V at the battery connection without a battery.

To find the error I was able to find out that +3VAWL, +1.05VAWL and...

Gigabyte motherboard missing CPU compatibility due to BIOS version being too low - proper way from here?

by survivalbloke

This job which came in is a Gigabyte B650M D3HP AX (rev. 1.0). It has BIOS version F1 currently, and the CPU installed is Ryzen 9 9900X, which according to the Gigaybte site, needs at least BIOS version F30. I don't have a supported CPU to install for the purpose of updating the BIOS. I have downloaded the BIOS from Gigabyte's website and unzipped the file "B650MD3HPAX.F32a". Can I just rename it to 'B650MD3HPAX.BIN' and flash it to the motherboard using neoprogrammer and my CH341A?...

I have a MSI ge62vr Apache Pro 6RF. I'm having an issue with this repair that I haven't been able to find a resolution for with my usual sources, so I'm coming here on recommendation from Reddit. A customer decided to attempt to manipulate voltage to the fans through the EC, his laptop shut down and he was not able to get it to come back on. I did a power flush, EC reset, etc. didn't work. Took out my multimeter, no power was going from the charger to the battery. Checked with a different charger. Power was going from the charger to the inlet, but not the battery. Replaced the power inlet, and...

Black screen on Sony 65x90ch (65x900h from Costco)

Weird issue with this tv. Was streaming to the from a computer when it stopped working and the screen went black. Ever since then there has been. o image. Just a black screen. The audio works and yhe backlights do come on when it's powered on, it's just a black image. It presented like a backlight issue. So I finally got around to getting new backlights and a backlight tester. All of them test the same as the good backlights with the same voltages. There are no blinking lights. Just the white led at startup and when buttons on the remote are pressed signaling it's receiving from the remote....

TCL 65S450F no logo, bleeping sounds?

by CapLeaker

Got a brand spankin' new TCL 65S450F here. Plugged the TV in and it booted up and wanted a firmware update right away. O.k. I guess it did that or not... I got no forking clue. Came back in 10 mins later and the screen is black, backlights on. The Standby light is blinking and every 10 to 15 seconds makes bleeping noises. That's all she does. Tried a factory reset and that must work as I can adjust the volume of the bleeping and it returns to factory volume afterwards. Also tried big black button with the circle right button on the remote and no go.

EDIT: No bootloop the bleeping...

Trying To Fix: Samsung UN50TU7000 - Weird Fading Screen then Red blinking light

by KYBOSH

Picked this up to resurrect.
When I plugged it in it comes on for about 1 minute... after a minute the screen blacks out and I gets blinking red lights on the power button.
I read that a common issue with this model is a failed BGA so I ordered a replacement on eBay.

Sometimes the TV would produce an expanding blob on the screen before going black.

Samsung QN65Q6DRA issue

by EazyBone

Yes I see the 75q6 post but this problem is slightly different and a 65

Plug in TV and Samsung QLED logo shows up then backlight stays on and no picture. I also do not have sound that I can see. When I hit volume up and down the led responds on the TV and flashes. I decided to solder jumper for 1/3 and did half ribbon. The same thing occurs I get half the screen for Samsung QLED logo and then no picture. This happens on both sides. Neither side shows a defect (at least in the middle of screen). The power board was tested and it's fine all voltages correct.

Any advices...

HP Spectre X360 Convertible.

Windows does not show a battery installed. Is using aftermarket battery. If I disconnect the power adapter, the laptop remains powered up.

What I've tried:[LIST][*]Replace battery with new aftermarket unit[*]Reinstalled Windows[*]Updated BIOS[/LIST]Coming off the DC jack, I have charger voltage on red, but on brown(I suppose is sense wire) I have only .45V which I believe is low, is it not? Shouldn't sense voltage be a couple volts less than charger voltage?
