Greetings, everyone!
Would need some help with this mini PC, the issue is - after turning on, PC starts, but there is no picture on the screen, no reaction on LED in external keyboard. Tested with another known good RAM. All voltages are present. Looks like BIOS issue to me, right? I tried binary from this site --> [URL]https://www.gigabyte.com/Mini-PcBarebone/GB-BXBT-1900-rev-10/support#support-dl-bios[/URL] ( version F9 ), but still same behavior. Note, I flashed only BIN file from that archive. Although, it says "1.0" in the linked site, but I have board with 1.1 revision....

by J8rda7Hi,
the TV has a black screen. Sound OK, backlight OK.
When I measure T-CON voltages, there is VGL+VGH=0V. After unplug the right side of the screen from the T-con, voltages are OK and half screen works normally.
I tried to search for any kind of short on the right side, but I had no luck. I have a beginner experience in measuring and repairs of the LCD panels..
Thanks to anyone who can guide me in solving the problem.. and be patient with my english 🙂😁05-13-2024, 11:04 PM -
by jm1234Hi,
I'm troubleshooting a power supply board and one opto coupler seems shorted. It's a through-hole, marked with 3 lines:
1223
816A4
W
I'm not sure what replacement to buy for it. It resembles LTV-816 ([url]https://www.tme.eu/sk/en/details/ltv-816/optocouplers-analog-output/liteon/[/url]), but I'm not sure it's 100% that. The data sheet shows multiple sub-types like 816M, 816S, but 816A is not there.
I do have other functional pieces on the same board, so I could do some measurements on those, but I'm not sure what to check.
Any idea appreciated.Hi,...Today, 03:30 AM -

by chth96I want to replace samhwa RG 250v 1uf capacitor which has no ESR value and has capacitance less than 280pf.
It is possible to purchase WCAP-ATG5 in local electronic shop.
But I want to know that whether WCAP-ATG5 capacitor has similar or better quality than smahwa capacitor or not.
Is there anyone who has experience to replace any bulge or faulty cap with cap from Wurth Elektronik?

by ianbakHi,
I have an HP 255 G8 that runs for as long as its battery holds charge but won't accept AC power.
I have partially diagnosed the problem and the issue seems to be that there is no ACDRV output from the BQ24735 to turn on the two input MOSFETs. The 24735 has a VCC of 19.57 V, the ACDET input is at 2.93 V and the REGN 6V LDO is outputting 5.98 V, so everything looks good - but ACDRV is stuck at 28 mV.
I've already replaced the 24735 and both input MOSFETs and nothing has changed.
I'd appreciate some suiggestions as to what to try next.Today, 08:45 AM -

by matheus30When I took it out it broke, and I want to get the same one or one of good quality.
Where can I buy it? On AliExpress they do not indicate the maximum amperages, and on Mouser or TME.EU it is impossible to search without having the exact reference.
Inductor needed:
It is the PP5V_G3S Coil of an A2159, 820-01598 (L7670)
On the front it says: 1R5
and in the schematic:
1.5UH - 20% - 12.5A - 0.017Ohm
PIMB062D-SM
152S00268
Can someone tell me where to buy it?
Thank you so much.Today, 11:44 AM -

by AlexVGHi,
I have Microwave BOSCH CFA634
It runs, but after 10 -15 seconds stops working.
Sometimes it shows error E1006.
I can't find this error explication.
Some people say it's communications error between main and display module.
Probably somebody has an experience with this issue?
Can you help me please?
Thank you an advance....05-17-2024, 05:17 PM -
