I get backlights that stay on not there is no image. The tv does not automatically power on when plugged in either which I generally see happen when there is a fault. It responds as it should to the power button.
I checked the test points on the TCON and I have proper voltages except for at 1P15V. I don't know if that is supposed to be 15V or 5V, but either way I only get 1.134V on that point. I have 12V, 8V, VCC, and a small amount on the CKV point.
I tried heating up the SoC on the main board but that made no difference. Disconnecting either ribbon from the TCON also...

by OmronI have a 5W lamp on 12Volts battery, I want it to be half as bright, so I will add a resistor. What resistor should I supply?
A = W = 5 = 0.416mA
_ _
V 12
R = V = 12 = 28.84 Ohms (R) this is resistance of lamp
_ _____
I 0.416
So I will add one resistor 28.84 Ohms
I will have 28.84 + 28.84 = 57.6 Ohms
Or 28.84 + 28.84 = 14.42 Ohms
I don't know if it will work in series or in parallel
voltage would be 6V and amp current mA = 0.208mA We divide everything by two

by NagyeszHi all,
Model: HP Pavilion 14-ce3010nh 8BV97EA
Board number: DAG7ALMB8C0 - G7AL REV C
Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck
I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....05-30-2024, 04:10 AM -

There is an U4 chip place, but no chip, between the battery connector and the charging port.
How should I progress to identify the problem?
Can anyone help me with this?...Yesterday, 11:20 PM -

by ProttHello dear badcappers!
The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?
[B]Backstory: [/B]
After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.
If there is a way to narrow down which memory module is faulty it would make my...Yesterday, 12:05 PM
