PS5 Encoder powers on to white light no video EDM-030

[Handealer]

Context I installed a new Panasonic video encoder and knocked off some caps after lighting damage.

My question is what should I look for while waiting for the caps to come in to make sure the encoder works? I am curious if the encoder was 100% install properly (How do I add images?). And if you think I should check anything else that would cause no video.

I would check the readings pads around the HDMI chip.

[Handealer]

Okay nice I was able to add images the aerial view you can see i am missing at least 3 caps and i accidentally put soldering on thag copper but i think its fine?

This image is after my first solder job which shows the caps (not currently what it looks like). Please dont judge to hard.

[Handealer]

Rough for me my AstroAi AM33B probes are too thick and they measure two at a time instead of one . Also an image of my solder job a bit blurry because I am using my phone for all of this. I am going to try to bridge my probe with my tweezers to get some reading. Also just to make sure I order the right caps the ones I need 0402 ceramic caps?

No, they are all 0201 size same as the small cap on HDMI PORT pin18/pin17

[Handealer]

Replaced caps and checked if they beep on ground and show volt on other side but I get the same issue.

[Calvin]

After lightning damage I would check the

1. four EMI filters towards the HDMI port
2. readings on HDMI pin 19
3. readings on HDMI pins 15 & 16

[Handealer]

All Filters give 0.917 v : when on ground it gives 0.812 v

Hdmi pins 1-19:

1: 0.812 v

2: Beep 0.01 v

3: 0.812 v

4: 0.812 v

5: Beep 0.01 v

6: 0.813 v

7: 0.813 v

8: beep 0.03 v

9: 0.812 v

10: 0.812 v

11: beep 0.01 v

12: .812v

13: .679 v

14: OL

15: .5 v

16: .405 v

17: beep 0.03v

18: .281 v

19: 0.684 v

Some seem low but I would assume enough to give some video.

[jkyoho]

PIN18 TOO LOW, should be around 0.5~0.7v diode

[Handealer]

Yeah my tv is reading it as a ps5 so I am getting closer. With the images below do you think this is bridging which is causing that voltage problem?

[Handealer]

Followed this to the back and found the same reading as pin 18 on this chip

[jkyoho]

remove that 6leg switch controller IC and check the 1st pin(bottom left from your picture) reading comes back 0.5v or not. The 1st pin is 5v stand by should not have 0.281 low reading

[Handealer]

Also this chip not sure if that is supposed to be 0L

[jkyoho]

yes, that 4th pin is NC not connect to anywhere

[Handealer]

Thanks, I will remove this gonna take me a second. I am going to watch a video first then attempt.

[Handealer]

hdmi pin 18 is .752v

and pin 1 is .757v (with red on ground and black on pin 1)

[jkyoho]

Are these measured when chip removed? Can you check if pin1 has continuity to F7002?

[Handealer]

Yes chip is removed and how do I check continuity to F7002 (not even sure what that is)

[jkyoho]

in diode mode or beep mode: one Prob(red or black) on f7002 and then the othe prob on pin1(black or red).

Or you could measure diode reading on f7002, if reading same(0.757v) then you should have continuity.

[Handealer]

Just so I understand you want me to touch the letters and or numbers on f7002 and then touch pin 1 of the spot where the chip was removed? sorry this is my first time doing this stuff and I think it matters which probe I use for my measurements since it has continuity and diode mode on same thing.
