Hi,
I seem to have a short with or without a capacitor. I've removed the power management ic which was above 100 degrees. Short is still present.
Ideas please.Today, 10:47 AM -
LEDs TV work with the Power to Main Board cable disconnected.
If the cable is connected red light no present, STBY pin oscillating.
I replaced the Main Board 2 times with same result.
Now the weird thing: With the TV connected and the LEDs lighting up , I connect back the cable to the Main Board, the TV turns off but the red LED light up and you can turn ON and OFF the TV working perfectly until you disconnect the power.
When you disconnect the Power the TV return to the previous situation.

I have two P4P800SEs, a P4C800-E Deluxe and all three boards show the same issue: difficulty POSTing (getting stuck on POST code 0D), or crashing under light load (but bizarrely, the P4C800-E is rock solid running Prime95 with a water cooled 4.3 GHz Pentium 4 3.4)
Should I consider recapping the boards? If so, what caps do I need? Is polymodding these boards worth it?
Do note I have never recapped a board myself, nor do I own good soldering equipment to do so.Today, 11:02 AM -
I have had problems with a Dell that turns on but does not give video, I ran the Bios thinking it was going to be solved but no, it has all the voltages 5 Alws and 3 Alws, but I was checking the schematic and in pum01 I have no signal on the pin #7 (S3) which is the DDR_VTT_ON signal of 0.6v, can anyone help me?...08-16-2024, 03:34 PM

Hey there,
I got a HP Elitebook 820 G3 Engineering Sample Laptop and I want to use it. Besides the difficult things at the ES-BIOS I have a big problem by saving the main BIOS settings.
The laptop does not have a big battery because it was dead, but I already plugged in a new CMOS battery.
It takes about 5min without power and the BIOS settings are lost. Unfortunatly I dont understand why the BIOS settings are only saved with power connected and this is the reason why I registered here.
As written above, I plugged in a new CMOS cell and checked...Yesterday, 02:28 PM -

Hi i have a smd part with probably mark "QO 11" or "Q0(zero) 11" on it, and its package is SOT89, i doubt its KTB1260 PNP transistor, but in measuring with diode mode of multimeter it shows number 1.4 between emitter and collector pins and its not open circuit, and .59 from collector to base and .8 from emitter to base , and these numbers doesn't match a pnp transistor, i couldn't find any part number and datasheet for it, does anybody have information for that part number?
I've attached pics of this part
Thanks...Today, 02:50 AM -
As the title say I need the shematics of the HP EB 820 G3 to find the signals RTCRST# and SRTCRST#.
A small guide or just a picture would also be sufficient.

Hello.
I bought a G5 for my self, at a low price, i knew it was faulty, so the fault is that does random boot loops.
I tried RTC reset, BIOS update, replaced thermal paste with MX-5, checked fans for dirt, disconnected all flex cables (daughterboard usb, keyboard, trackpad, wifi, m.2, replaced RAM) but still the same.
This behavior can be a faulty GPU/CPU or if any of these components get faulty the laptop shut down completely?
When i get luck and enter Windows i see everything in device manager without exclamation marks.
Any advices or thoughts welcomed...Today, 07:41 AM

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...08-08-2024, 01:37 PM -

Hello,
I have a 42" Vizio TV. I hooked my tablet to the HDMI inputs. Everything was fine until the screen went black and now the only input that works on the TV is coax. No hdmi, no component, no rca. I tried hooking up a laptop to the Hdmi port and the computer
detected the TV model but no image.
Is there anyone having the same issue? Did you find any solution?
