No indicator light. No sound. The white connector is for the LED's and nothing on any of the pins. -
Another Cheap TCL issue I need some help with
I have in a TCL 65S4 TV that is dead it seems. I did some research and looks like everyone says backlights. I managed to get the screen off in one piece and checked the backlights with my tester and all are working same brightness. I got it back together ok and tried turning on again in a quiet place and nothing no screen even with halogen light against the screen. Next thing I see popular is the power board so got one from eBay from a "cracked screen" tv. And still nothing. Could I have another bad power board or go for the main board right away? Can the experts tell me how I can check...

Delco bluetooth mod help.
I'm trying to add a bluetooth module to my 99 Delco truck radio. The videos I have found are not quite right for this model. The module is not the problem. It seems to power on and I can connect ok with my phone. I watched this video for the wiring since it looks like what I have.

It seems like I need to activate the CD in order for it to use the sound from the BT since that is where it's tapped into. Any ideas or has someone done this before on this model?I'm trying to add a bluetooth... -

lg 46LD550 HDMI no sound
I got in a LG with no signal on HDMI ports so I replaced the HDMI IC and now I have picture but no sound on just the HDMI the other inputs are working fine for sound. Any ideas? Would the amplifier ic have anything to do with just HDMI?... -

Re: Hp ZBook 17 G3 Not turning on sort of ???
This is just left of the 2 mosfets. Not sure if it's what you want. Hard to read but top line looks like BQ next line looks like 24780S next TI 571 next AYZY...Leave a comment:

Re: Hp ZBook 17 G3 Not turning on sort of ???
Is this what you need? Also might not matter but that mosfet under the thermal camera was pulsating warm/cold over and over just with cord plugged in....Last edited by CraigR; 03-29-2022, 04:51 PM.Leave a comment:

Hp ZBook 17 G3 Not turning on sort of ???
I have an hp ZBook 17 that will not turn on with the power button. I do have a charge light. I have the board out and the switch is good then I found something not making sense to me. A mosfet (see pic) has 19.9volt at the drain but nothing at source or gate HOWEVER if I touch the gate and ground with my bare finger I suddenly get power and can turn on the laptop with the switch and boots and runs fine. I did replace mosfet but same results. Not sure why the small resistance in my body to ground would get it going?... -
