Re: belinea 101750, lights led once
yes, the caps are samXon. that was what i thought, a full recap. today im gonna shop for them, what do you recommend me?
i dont think its backlight related as the green indicator led lights only once when the display is connected to the mains, and then it is all dead. i am worried about the 2.3V output, im convinced it should be 3.3V. thanx anyway.

Re: belinea 101750, lights led once
YES! Your pictures are quite bad.
What are the caps - samXon??
I have attached part of a picture. Is the item circled red and yellow a cap?
Cant even tell.
Of the other two the top one looks as though it has leaked- has it?
The lower one looks bad but it may just be the picture. is it?
I think you should consider a full re cap except for the BIG Cap
May be a good idea to list the caps and manufacturer and series.
Can you test the backlights on another monitor?
If what I can see looks this bad its a worry what I cant see.Attached FilesLeave a comment:

belinea 101750, lights led once
hello friends!
i must excuse for the quality of photos first.
i have this old monitor with the following problem. it lights only once the green led, when attached the AC plug, and then no more signs of life. i searched the forum and i saw sth about a 3.3V output from the PSU. this PSU has a steady 12V, 5V but no 3.3V. instead it has a 2.2V. normal?

Hi:
i am trying to repair this Christmas lights from my parents. They are incandescent lights, no led lights.
I have tried with 12V a 24V small lights that I found in Aliexpress but is obvious that are not the right ones. They last microseconds connected. Do they blow because of Amps or Volts?
If I measure the Amps in the string........it's only 90mA. If I measure the Volts in the "green box"......it's between 0 and 190V, but doing a little bit of maths from the number of bulbs in series.......it's only about 6V per lamp.

Hello,
I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.
Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,... -
Hello everyone!
Please help me determine which microcontroller was in this place.
Logically, I guess that this is a ddr4 PWM memory controller and some kind of Richtek, but which one?
Thise motherboard came after another service, where they say that water got on the controller and it burned down and they dismantled it.
They did not take photos before the intervention
The DANJLFMBAB0 REV B board, schematics, boards and photos of the motherboard were not found on the network, but I may have searched badly-((
Maybe someone has a photo of this piece,... -
Does not turn on, lights 3 of the 4 LEDs and turns off and stays like this, presses the power and repeats.
I saw that the room LED lights up only when the screen is connected, so quiet.
We have all the power supplies, even processor, 1.8V
One thing I found strange, it has a very low resistance in the Vcore is giving 1 Ohm , work with notes and such, I know that this is normal in some processors but with this resistance only take video card so found it strange.
I suspect that there may be some leak in the processor.
Anyway, when I press the power, it... -
My Mom bought some cheap motion sensor lights on wish... then complains about about batteries and this thing chews though them, well it uses 4 AAA batteries and a pack of rechargeable ones is about 13 USD
well since it uses 4 AAA and rechargeable are 1.2v and non-recharge at 1.5 this thing must work with 4.8-6v, I'll shove a USB cable on it, infant i will use a broken phone charge cable... dam this thing uses 430 mA and they made it battery powered...
lets ignore the fact that i thought the board fit both ways... and the wire color is reversed going to the board...
