Hi! Got a CECHA00 with instant YLOD.

Got these errors after getting syscon access:

Console booted after replacing Tokins on the Cell side but without image over HDMI.

• Sometimes It randomly shows a screen for a few seconds with artifacts then blacks out.
• AV works fine.
• Monitor and cable works with other PS3s.
• Checked the HDMI port and related components, everything seems fine.

The only odd thing i found is getting measurements from VDR257 and VDR258 (103.1 ohm and 19.3 kohm respectively). I can't get any measurement at all from VDR256 to VDR251.

So if AV works fine can the RSX be left out? In the end IC2502 seems to be the culprit here, does it make sense? Is there anything more to look for?

Thank you!

Start by replacing VDR 257 and 258. They should read open circuit (OL)

Removed them and HDMI worked. Was able to resolder a pair of new ones from a donor board afterwards. Thank you!
