Hello,
I have a Sony DVD player with a stuck tray. It seems that moving or pressing on the tray makes it work.
Anyone knows why?
Thank you....Yesterday, 04:29 PM -
by E--ManHi All,
Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.
Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.
The lines are green in color when the tv is in "Game Mode" and...5 PhotosToday, 10:52 AM -

by GraphicManHello 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...-

by PITERPENYHI. I need help with this board! 5v/0a stable. Replacing the u7000 did not change the situation. Before I move on to replacing the SD3215, maybe there are some tips on what to pay attention

by xerooneI have a Lenovo E15 Gen1 that refuses to boot, power light flashes 3 times then stay on, but laptop is dead.
I can connect and read the BIOS chip, so I'm not sure if its at fault or not.
If someone could take a quick look, that would be great.
Many Thanks...-

by sam_sam_samI have a 24 volt version of the same type of switching power supply but that one I am relocating to meter module and I might do the same thing with this one but I have to modify an enclosure that is not made for this type of switching power supply in fact I am not sure exactly what type of switching power supply it actually fits because none of one's that I have the screws holes do not line up and not even close but the switching power supply fits in the enclosure
So I have take out the switching power supply board out of its enclosure and drill the hole so that it can be mounted...04-14-2024, 05:45 PM -
by unimatrix93Can I ask you guys help me identify this godforsaken component?
I'm tearing my hair out finding this component.
The board is from an egg incubator.
i got it with a "popped cap" while there are many damaged components on it, which got succesfully identified with one exception:

I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.
Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.
Any idea what the problem is?05-06-2024, 01:36 PM

by RomanSko1Hello, 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?

by EpagecHello 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)

by budwichGot 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
