PS5 SLIM, EDM-044 HDMI ENCODER shifts to new chip

jkyoho · Apr 17, 2025

I just realized this new board has different HDMI encoder RTD2175P when I was repairing traces on the HDMI PORT and measuring different diode reading on each pin.
Seems like we might have more legit resources to replace HDMI encoder rather than the refurb MN867439 from random nowhere.

The MN864739 is a QFN80 chip. The new RTD2175 seems to be only QFN56.

So I have literally just tried a RTD2175 from aliexpress and it didnt work.Unit powers on but no output at all. Just thought i would post this before someone else wastes time and money trying. I cannot seem to source a 2175P chip anywhere sadly. This was as close as i could find.

Rtd2175 series is quite newly released by Realtek. I haven't seen anywhere has this 2175p for sale neither.

you can get RTD2175 easily but not a RTD2175P...assuming the P stands for proprietary at this point lol

RTD2175N might go for Nintendo switch2.... so my guess P stands for playstation lol

I would tend to agree. I have soldered down the 2175 chip earlier and it was soldered good. It would power on the unit but would just flash blue. It was an EDM-044 board

Can you show the other side of the HDMI on the motherboard!

What would that achieve?

Does anyone have Diode readings from around this new chip? trying to verify if this is my issue.

RTD2175P DIODE READING uploaded here for anyone who needs it for reference.

FYI, 5v_SWON(pin18) in the picture is only present when fully boot up, i.e 5v power for usb port

The RTD2175P is available on AliExpress but the price is over $100.

Yeah over £70 in uk. Will wait until they become cheaper

Good evening everyone. I also have a problem with this EDM 044 and the HDMI encoder. I have a UART code with a problem on the 0.9V line of the HDMI IC. I changed the encoder, but that didn't solve the problem. I can't locate the 0.9V line. If anyone can help me, I'd appreciate it.

There are two 0.9V lines. One (neon green marking) generated from the 1.8V by a little 5 legged converter and one (light green marking) 0.9V by a qfn chip 'RJ='.
