Help with diagnosing faulty PS3 HDMI

[ushir]

Hey guys,

This is going to be a bit of a lengty post as I would like to describe the entire problem.

To begin, my satelite dish was struck by lightning, sending a surge through my satelite decoder, then into my tv, then to my ps3 via HDMI which has blown something on the ps3 related to HDMI.

The PS3 still works via AV - but when hooking it up to HDMI it just displays a blank screen. However, when connected via AV and attaching an HDMI cable as well, a message pops up saying that an HDMI cable has been detected and if I would like to switch. When clicking yes, i am met with a blank screen. So it appears some portion of the HDMI port is still working.

I have tested the port with a multimeter and found that either PIN4&5 or Pin 15&16 read 5V (Im not sure which pins they are because I am not sure what perspective the HDMI diagram is drawn from - http://en.wikipedia.org/wiki/HDMI). Every other pin reads 0V DC.

I compared this to a new fully functioning PS3 and got the exact same results. This leads me to believe that the HDMI port itself it working but that the problem is deeper - perhaps the HDCP Silicon Image chip?

How do I go about diagnosing the problem? I would like to know if there if a dry joint / solder somewhere which is easily repairable - that way I can save my old ps3.

Thanks guys!

Lightning damage is almost impossible to predict. Inside lightning damaged equipment, nearly anything could be bad, from connections, to chip internals.

If you are skilled at soldering, you can re-heat every soldered joint. If there is a hidden crack, that might fix it.
