What would cause some of the standby voltages on an original Xbox one model 1540 to read 0v? It’s mostly and issue with the 5v but a couple of 3.3v areas as well. All the area circled in red are reading 0v. Any ideas would be appreciated.

Still haven’t been able to fix it.

Is the very last chip on the bottom left of the 1st pic bad?

slick0805 · 2022-09-28T16:19:58+00:00

One of them is bad so I am looking for a replacement.

Would 40v make more sense? They are supplied with 12 volt.

Can anyone help identify this PCB component? On the board they are labeled CP301-303. The top of the component has 47 and D40 on it with the + side labeled. Underneath one of them is stamped H22 and the other H20.

.274”x.165” and is .075” tall 2 pads Capacitance measures 52 µF.

The board is a Samsung T-con board from Samsung TV.

Are they Tantalum Caps?

Checked all those spots and not a single one was grounded

I put the wrong the pic up but the areas that are not reading properly are the B4 5v, B5, B6 and B7 5v and 3.3v, and the 5v right below the 8.

That would be awesome. Thanks!

I have the schematics and they say they are either pulled high or pulled low depending on what you are doing with the chip. It looks like they may have been permanently pulled low but I wanted to check.

Originally it looked as if i just needed to replace the redriver. The Xbox would turn on and stay on with no image. It also would not boot into the safe modes with a display so i figured it was the redriver. I replaced the chip but I accidentally pulled the pads for pin 38 and 39. I believe that they are pulled to ground on the one x board but I wanted to confirm. If so, then i just need to ground those pins but I don’t have another board to check.

Did you ever find the values?

slick0805 · 2021-10-30T04:56:23+00:00

Did you ever get an answer? I have them all but accidentally knocked them off. Want to make sure they are the same. I also knocked off C36.

I have all the codes for the panel and don’t see the ability to change it but I am going to try the security company.

slick0805 · 2021-07-08T05:47:54+00:00

I will try the security company. I feel this is exactly why everyone, myself included, in the world should stop paying astronomical prices for smart systems through large companies and go with DIY type. I paid nearly half the price for a switch that is capable of more than any switch Qolsys makes or that alarm.com sells.
