Re: LCD belinea 2025 s1w no baklight
1. While some people have a library of photos of different monitors, there is no systematic list. That is why you attach pictures of your monitor using 'Manage Attachments'. Note links in my signature for hints on providing good pictures.
2. What brand and series of cap did you use as replacements?
3. The problem you are describing is 'Two Seconds To Black'. Common causes are bad capacitors, a problem with a CCFL (age related, or broken), the CCFL wiring (frayed or broken lead), or a bad transformer.

Capxon is a known bad brand, considered 'replace on sight'. KSC is a known bad brand, not recommended. I have located the manufacturer's website, they have very little information available, so I have no idea if the caps you installed are low ESR types. General Purpose types will not work.
I prefer Panasonic FM or FC series.

Hi all,
I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.
I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.
I have tried a few new bios but exactly... -
Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for... -
Good evening, gentlemen.
I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.
To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

A Harman/Kardon AVR 645 repair has been a hobby of mine for the past several years. My latest attempt involved the purchase of a DOA unit for part swapping and testing. The original AVR would power up then shut down after a few seconds. I completely tore down both units, found a couple of bad components and reassembled one of them. Same issue, no speakers connected. After extensive research I found a repair document from Harman/Kardon that explains the protection circuit in fantastic detail and provides specific test points for each fault (power, DC detection, overload & power) and the voltage...06-17-2024, 11:43 AM -
Hi,
It have had a problem with U7100 and short circuit in Q7130.
I replaced them.
It starts now and waiting 20 seconds and then starts to reset PM_SLP_S4_L every 10 seconds.
Almost all voltages rising
except U3090 and U3210 (LED) - not receives enable signal.
U4500 is trying to rise - receives enable only 2-3 seconds
Here is my measuring of important signals.
What else could be the problem?
I need to help.
Thank you an advance....
