Got this projector which has a problem with a lack of blue. Menu text is very yellow... expecting white. If I input a signal from a test disc via hdmi, a red screen image shows a uniform red as expect. Green similar while the blue does show but with non-uniformity. Looked at the in-polarizers. They are all good and clean. Running the projector to expose the light area in the prism block, shows each color well represented, all looking about the same intensity from the naked eye. Looking at the prism block itself and sending a light source back into the "out port", the individual...05-10-2024, 06:49 PM

Hello, this might be embarassing since I consider it a dumb question but keeps me kinda stuck sometimes in my journey.
I want to know if there is any post in this forum which explains my questions. [B]A)[/B] [B]When, where and how do I know when X voltage line is input or output. Example: [/B]

Hey guys got laptop like above. Came to me with shorted main power rail and battery protecion on ( 0V on output). Got rid of short but nothing. Bench power supply says it takes nothing, but still got all voltages 1,2v,3.3v,5v - all good. Thermal cam showed nothing is starting even for a sec. I believe that since all coils etc are good resistance to ground it's probably one of chips. Can be IO chip or maybe something else? Could somebody help me out with this one - it's blowing my mind lolToday, 01:53 AM

Hello everyone
I have this compaq Armada 7730Mt (pentium 166. Mhz 1mmx laptop)
It's working well except pccard slot not working and fan not spining.
I have a short on what I suspect to be a 12v rail (related to the fan)
As you can see I removed the coil, it's ok no short on upper side but I have only 0,2V and the down side is shorted
When I inject I have 3amps at 1V but nothing going hot with thermal cam.
Do someone knows this board and could tell me which voltage rail it is (and what it's used for)
I don't...Today, 04:08 AM -
Hello guys
Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing...05-05-2024, 06:20 AM -
Hello, gentlmen!!!
My HP Probook 430 g2 does not detect battery. I tested the battery on another laptop and it is OK.
I believe smth is wrong with my PC ((.
Searching this forum I found some nice suggestions.
So, I tested Battery Connector pins (charger in/battery out) and here are my results:
pin_1 0v (-)
pin_2 3.30v
pin_3 0v
pin_4 3.38v (SCL)
[B]pin_5 2.55v (SDA)!!![/B]
pin_6 2.25 (+)
As far as I understand SDA pin must be ~3.3v???
Are there any other tests I can do before disassembling motherboard?

Hello everyone from Italy, I'm here to ask for help on a Vestel TV, I've had a Vestel TV branded "XD" with a broken screen for years, but now I've found a Telefunken (still Vestel but older) and I've mounted the panel on the "XD" TV, it works, but the screen is upside down, given that Vestel does not allow you to rotate the image from the service menu, does anyone know how to solve the problem? the original panel is marked ves315WNDS-2D-N12 while the main board 17mb110, the panel I mounted instead in the tv (from the telefunken) is a ves315WNDA-02. ... It is not worth repairing...Today, 05:22 AM

Hello all,
I have a Lenovo Think Station P700. I bought it second hand in order to use it as a server for home use for testing purposes.
It was running Windows 10 when purchased and I did an update and the BIOS stopped working. I took it to a repair shop and they couldn't find the BIOS for the P700 and told me they put the BIOS from the p500.
But at the moment the BIOS is missing Intel ME. It only shows Intel ME Firmware Version N/A. And current state is: it stuck at Lenovo logo.
I'm not a professional, but I have a CH341a and did a dump of the current BIOS.

Hi community! Germany calling
I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!
I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...03-20-2024, 07:29 AM -
