AI Thread Summary
A PS3 was damaged by a lightning strike that affected its HDMI functionality, resulting in a blank screen when connected via HDMI, although it still works with AV. The user tested the HDMI port with a multimeter and found some pins reading 5V, similar to a functioning PS3, suggesting the port may be operational but the issue lies deeper, possibly with the HDCP chip. The discussion highlights the challenge of diagnosing lightning damage, which can affect various internal components. Recommendations include re-heating soldered joints to potentially fix hidden cracks. The user seeks guidance on diagnosing and repairing the issue to save their PS3.

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.
 
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
