Re: Noco Genius 10
Capacitors checked. There is also a pfc circuit that boost the dc voltage to 380vdc. I managed to trigger it and the input dc voltage to the chip was correct, but the power supply still failed to work correctly. At that time the secondary voltage was around 4v rather than 15v. Just to make sure I ordered a new psu chip, but I don't think it is the issue.

Re: Noco Genius 10
Unfortunately all led's are flashing, not just those you mentioned. Am trying to reverse engineer the pcb so hopefully will get to the issue. Measuring some voltages, the power supply is also flashing on and off. There don't seem to be any shorts though on the secondary side. Something is forcing the psu shut down then reboots again.

Noco Genius 10
Hi members, have a noco genius 10 that has all led's flashing. Did any of you come across this issue?
Thanks

Re: LG 32LE4500 LD01D - stays black no pic
Hi all, i have the same problem. Power led red, then white but no picture. Measuring voltages IC1002 is not giving the ok for the inverter board and t-con board. Other voltages seem to be ok. There seem to be no error signals. Forced On the back lighting and all lit up well. Tried to reflow the processor but same result. At this point the tv is quite old and not worth is buying a replacement main board. If someone can give out some help, that would be great. Otherwise the tv unit is just scrap. Thanks

Re: Samsung bn95-00944b t-con
Attached a photo of the t-con board that has problems. These are the current voltages on inductors:
1: 2.5v
2: 1v
3: 0v
4: 15.3v
5: 3.2v
6: 12.3v
Also the voltage on the main fuse of t-con board is 12.35v...

Samsung bn95-00944b t-con
Hi all, I have a Samsung tv that has a vertical side of the screen very dark. The backlighting is good. Doing some testing on the t-con board bn95-00944b and am not sure about the voltages i should have on the inductors. Does anyone have a list of voltages? There is one inductor that has 0v on it, while its mosfet has 15v in the gate driven by THV3056 out_vgl pin. Am guessing the thv3056 is defective. Thanks
