Which IC do you mean. PU200 is +3VALWP ,+5VALWP .Pin 18 is not connected. -

If there is no +3valw and +5v alw , Then first check pin16(VIN) and next check pin 8 & 17 for voltages. Have you checked resistance to gnd(diode mode) on PL200/PL201??Comment

Hi there, I have an Xbox One original in which I have all the 1.8v, 3.3v and 5.0v standby power rails present, however my 12v rail is not turning on and the enable signal PSU_V12P0_EN from the SMC to turn the power supply on is missing. There is high resistance on this line so it's not shorted directly to ground which leaves me with not many options.
Was looking at a schematic and see the enable is created by the SMC. I have 3.3v on SMC_RST_N_IN but I'm a little stuck on where to look next. Is it likely that the SMC has gone bad or am I missing something else (it's my first time with... -
Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
Good morning.
I have posted here before and have gotten AMAZING advise (thank you!). I'm back for more. This BCaps Sub Forum is so well attended I thought I would post here.
This question is for an automotive application but has to do with what are essentially electrical questions and problem solving... If this is inappropriate I get it. Feel free to delete it or move the question.

Hello all,
Working on my first C64 / Breadbin / 250407. Purchased as non-working. Getting black screen.
More detail below, but for those that want to get right to the question.... Here are a few waveforms comparing the Pin15 output on the VIC chip (luma/sync) to the pin 4 on the AV socket (composite signal).

My question is: Is the composite waveform range of 0.1v-1v too low for a c64?
More detail:
Symptoms are that that I get... -
Hi, guys!
I am not a professional, all I can do is solder stuff on the boards, so I would really appreciate it if someone with knowledge shares his experience/thoughts on a problem I have with a PS4 console.
My friend gave me an original fat PS4, board model SAB-001, with WLOD, that has been previously opened. I changed the HDMI port, couple of pads on the board were ripped, which I connected to the corresponding caps/resistors? Just did so as in a shown diagram (one of the ground pads I ripped off and left it not connected). However, there was still no signal, so...
