Hi I have inherited the above desktop scanner, all seems to work correctly but there is no sound output. The only sound I do get from the speaker is the beep confirmation when you press a key. No output from the headphone socket either. Not even radio static with squelch fully turned down, tried a reset by holding 2, 9, and hold buttons but still no sound, does anyone have any experience with these scanners, thanks.

To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...

Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.

(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.

Any insights on what might be causing this?...

I found a short on a mosfet in the vrm and used my air station to remove the bad component. and after viewed my work and noticed that had also blew the cap above it off as well... it went to cap heaven. I don't need the boardview file just what cap values are needed to replace the component. This is on a gigabyte r927xoc-4gd Windforce. I am a novice at repairing as that was a rookie mistake, + side is removal of the shirted package cleared up the short.

I have a Lenovo E15 Gen1 that refuses to boot, power light flashes 3 times then stay on, but laptop is dead.

Hi 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...

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...

[Mugar]

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 lol

This crossover was bought new about 12 years ago, and has probably been powered on for at least 3/4 of that time. It also has a recently developed horrible sound on the second channel, sometimes it's a wub-wub-wub, sometimes it's just a hum that comes and goes. It's not noticable if something is playing (it may be gone), but it's quite noticable if there is silence.

Because of age and problems it's due for a recap. I'm also strongly considering putting in sockets to potentially replace the 12 ST TL072 opamps. For such a small device, it's still going to be over 30 screws to take...

I have an old Mikrotik board with one bulging capacitor. It still works, but the cap doesn't look healthy.

I have tried replacing it, however it seems to ignore my soldering iron like it's a toothpick. I do suspect an industrial-strength lead used during manufacturing.

How do I remove it without damaging the PCB and (more importantly) surrounding components which might be more temperature-sensitive.

Hi there,

Where could I check to find the fault?

Don't want to replace that one when I can just test other...

Picked up a used MSI Ventus 1660 super with no video output for $50 to dip my toes into GPU repair. After some lurking around here, google searches, and youtube videos, I've gotten around to checking resistances, and checking for the base and minor rails. On first inspection, I didn't any shorts on any rails, so I powered up the card, and found the 5v, 12v, 5v, 1.8v, and Vcore(I hadnt found the 3.3v location at the time). Later, after finding the 3.3v, I got a pcie extension and powered up again. This time I found the 12v. 5v, 3.3v, 1.8v, Vcore, and Vmem. Later, when I wanted to doublecheck my...

Hello all.

I am trying to repair a Gigabyte Z490 Aorus Elite AC motherboard that was roughly handled. It had some components ripped off the bottom of the board. The last two I am trying to replace are shown as CKA_FB1 and CKA_FB2 on the schematic and I think they are SMD 0402 30nH inductors to control the resonant impedance of the control rails. I have measured approximately 3.3VDC at CKVDD as per image below. On the board the still in place CKA_FB3 is 1mm x 0.5mm SMD component with a dark body.

I am not familiar with the symbols used in the schematic below if anyone...

5.3V on pin 4(EN_LDO)
3.4V on pin 5(VREF3)
1.3V on pin 1(VREF2)

But only 0.46V on pin 7(LDO)

Is this means Chip is gone?
