I lost one of the two hdmi outputs on a yamaha rx-a1050 receiver. Of course, it is the hdmi1 which has the arc capability which was useful. The second output hdmi works OK.

I got an hdmi breakout board which gave me access to the "little guys" in the hdmi. I did some gross DC voltage measurements to ground and found that the Data1 pair (4 and 6) had a lower voltage than the working hdmi.... 1.1v versus 2.9. All others pins seem to be OK. Further when plugged into a display, there is no video but a message on the screen which I assume is the display's status for the...

Hi, ill try to keep this short. I got my hands on a PS4 with a mangled HDMI port and assumed that it would be an easy fix. before the replacement it booted up fine (white light) however after replacing the port it booted up fine for 2 times and then after plugging in an HDMI cable and turning on the console to check whether it had video out it never booted again, even after unplugging the cable. now it gets stuck on the blue flashing light and after 25-40 seconds it pops out the disk (if one is inserted) and shuts itself off. Upon investigating i found that the capacitors near the HDMI port are...

I'm a little green when it comes to consoles. I've done a fair amount of hdmi port replacement but not really any diagnostics. I've got a PS5 here which powers up but has no video output. I've also tried to boot to safe mode, also with no video. The hdmi port does not look damaged.

Where do I go from here? Thanks!

**UPDATE** I take that back. The external part of the port looks fine, but look at the pins to the mobo. Those pads are ripped off. How does this happen when the feet of the port are still sturdily soldered to the board?

**UPDATE 2** The pads were...

Hello guys,
I try to repair a PS5 with a WLOD.

At the beginning I should tell that I get a BLOD and after the UART reading and shorts on the caps near by the HDMI Encorder I change the IC. And after the change I get a WLOD. I also noticed that the filters was blown. I change them also.

The caps near by the HDMI Encorder are not shorted now. I also change the HDMI Port.

I get some readings in Diode Mode which doesnt look right to me.

1. HDMI Pin 18 i get 0.100V and Pin 19 OL
2. Diode on the back side 0,100V...

Have an A2141 which is reading about 5.2V 0.07A on all USB jacks, started doing the measurements.

PPBUS_3GH diode: measures good .45V
PPBUS_3GH Voltage: maybe not so good 12.25V maybe bad T2? Unit did not come up in DFU on configurator.

The weird so far is
PP3v3_G3H_RTC_X diode: .104V (WTF?)
PP3v3_G3H_RTC_X voltage: 3.39V (Normal)

Stopped there attempted reverse voltage injection at PP3v3_G3H_RTC_X with 1V. Instead of the circuit sinking any current, My PSU suddenly reads 3.4V with no current draw.
Not sure what any of this means...
