work force pro printer 4630: Problem downgrading the firmware of an Epson WF-7840

Sat, 25 Jul 2026 18:16:04 -0700

Good morning everyone,

I've had the bad idea to upgrade the firmware of our Epson WF-7840 (version CD17M6 now).

Now, our non epson cartridges are not recognised anymore.

I've search the web about how to downgrade the firmware. I found the procedure, found how to put the printer in "recovery mode" and, on the Epson website, I found the "Recovery Mode Firmware version CB08LC" for the Epson WF-7840.

But it doesn't work...

First problem, the model of the printer does not appear in the "Epson firmware updater" but it sees that a printer is connected.

Second problem, and it is where it stops, when I launch the Update, it fails with a message on the printer's screen "Data file not found".

I tried with my mac (macbook pro 16" m1 max) and with an older macbook pro from 2009 with the same result. I tried with another USB cable and still no luck.

What am I doing wrong?

Epson Printer: Epson Workforce 1100 prints test page only

Fri, 24 Jul 2026 13:12:45 -0700

My printer sounds and move like it's printing, but the paper shows nothing.

I had cleaned the heads at least 10 times. The test page prints ok, but only.

All others print in white.

The noozle check shows yellow, cian and magenta, but no black.

Minha impressora só imprime a página de teste.

Já fiz limpeza de cabeças umas dez vezes. No Nozzle check aparecem as cores mas nada em preto.

Todas as outras tentativas a folha sai em branco.

Solid State Drive: Adata 256GB SSD died, I fixed it, now I can't recover data from it

Fri, 24 Jul 2026 05:10:24 -0700

I have an Adata 256GB SSD that just died all of a sudden, PC would not see it in BIOS, and plugging it in externally to other PC's would not do anything, it wouldn't even show up in disk management. I ended up taking it apart and reflowing it, and surprisingly, It Worked!

Now it shows up in disk management as unallocated, and my GetData Recover My Files software could see and scan it. Unfortunately, it could not find any files on it (I have always used this software for data recovery and have had a fairly high success rate with it).

Does anyone have any suggestions for software to recover data from a functioning (I guess) SSD? I appreciate any help. Thanks!

Brother Printer: Exit Fingers (Flaps over rollers near page exit) vibrates violently

Fri, 24 Jul 2026 02:32:26 -0700

I inherited a Brother HL-L2351DW printer recently from a cousin who was moving to another state. The printer was barely used and had only 80 pages in the page count. For a few months the printer worked just fine but one day suddenly the right exit finger (that plastic flap over the rollers from where the page comes out) started making a loud noise. On closer inspection i saw it was getting hit by the gears that push the paper out. The left side exit finger on the same printer on the same assembly doesnt even move while this one violently flaps as if its trying to break away. Anyone faced similar issues with their Brother printers and managed to fix it?

TP-Link Archer C7: Need help identifying an integrated circuit

Thu, 23 Jul 2026 12:24:51 -0700

Hello,

I have a TP-Link Archer C7 router (TL-WDR7500 Ver: 6.0) which needs integrated circuit marked U25 to be replaced. However, it cracked in half and there is no way to see the markings.

Would kindly appreciate for any information regarding this component.

Thank you.

GTX 3060: RTX 3060 No Display - Fans Spin but No Signal in Any PC

Thu, 23 Jul 2026 11:01:32 -0700

My RTX 3060 is not outputting any display. I have confirmed that the fans spin and the card appears to have power, but there is no signal to the monitor. I have already tried the following troubleshooting steps:

- Tested with different HDMI and DisplayPort cables.

- Tested on multiple monitors.

- Re-seated the card in the PCIe slot.

- Verified that the 8-pin power connectors are fully plugged in.

- Tested the card in a completely different PC, and it still does not work (no display).

Since the fans spin but there is no output in any system, I suspect a board-level hardware failure such as a missing 1.8V rail, a VBIOS issue, or a faulty VRM component. How can I narrow down which component has failed using a multimeter, and are there common failure points for this specific card?

This printer is about 3yrs. old. I've tried all the cleaning tips the manual suggests, still nothing.

Is there anyone who has a tip and or trick to fixing this? I've replaced the black cartridge several times.

I bought a case of ink for the printer so I'd like to be able to use it up!! Thanks.

I have a GTX 1050 (not Ti) which is showing blank screen. Looking at the pcb, it looks like some of the resistor/caps smds have been knocked off so any ideas what they could be?

Have attached a very high rez image. Ignore the slight wonkiness as its a stitched together image. Have circled and numbered where I've spotted missing components.

Help appreciated!

Asus VH232T: Backlight flashes very briefly, then stays off.

Tue, 21 Jul 2026 21:18:14 -0700

I got this display used, unfortunately it didn’t work right from the start. The backlight only flashes for a split second when turned on, then stays off.

Other than that the display seems to work fine, the image is definitely there (checked with phone flashlight), so I decided I want to try and fix it if I can.

Taking it apart was easier than I even expected. Unfortunately I couldn’t see any bad components on either of the boards (power supply and logic board, I assume), and I didn’t think to take any pictures at the time. Put it back together for now.

If anyone has experience with this model (or similar ones) and can point me to what exactly to look for that would be appreciated. I saw that other Asus models seem to have problems with the power supply? Where could I get ahold of a new one to try that out?

Edit: Took some pictures:
