I bought these LED light bars from Electronic Goldmine surplus store online
These light bars are the nicest LED light bars I have ever seen in there online store
I read the description of these light bars and said yeah right there bright at 9 volts
Let just see if this is the case or not and just how bright is bright because I bought some of there light bars that they said were very bright and were ok but I would not say they were as bright as they claim
But I thought I would give these a try only because they had both light bars on sale as a bundle... -
Hi everyone
Please help me with this laptop
HP Omen 15-dc0003la , MB DAG3DBMB8D0 REV. D
It doesn't turn on, when I connect the charger with battery orange light appears on power jack and without battery white light appear, it is fine I think
But if I press power button, power led flashes white once, only that, not consumes anything power, not start, nothing more.
Bios was programmed with a working version, no changes.
Voltages
+3vS5 = 3v when I connect charger, next goes to 0 (I think is fine)... -
Hello all,
I have Philips Oled 55 (804/12) with black screen and red light blink.
I have opened TV and tested voltages based on similar oled topics, on power supply board i am getting ps_o/f 3.3v and 5v for t-con_o/f while panel_o/f is 0v. And i get black screen.
Also i have done self psb test and i am getting on psb +12V_t and also + 24V for panel. (Measurements on dmm are + 12.3V fot t-con and 22.4 for panel)
When i power only psb and tcon with 4 ribbons for panel i only get black screen.
My questions is what should i do next... -
Hello everyone. I have a problem with an HP laptop, when connecting the charger the amber light comes on for 6 seconds, changes to white and does not charge, I have checked all the components with the multimeter and the values seem correct, I was guided by the diagram, I do not know if it is a problem with the BQ24728H charge controller, investigating it seems that the voltages given by the charge controller are correct, I made the measurements connected to the power source and without the battery:
- ACN (BQACN) 19.6v
- ACP (BQACP) 19.6v
- CMSRC (BQCMSRC) 19.6v
- ACDRV...
