HDMI Problems on a Lightning Stricken Plasma TV

It just couldn't be the one thing I already fixed.

I have a second channel:

[coooooooooool]

its entertaining to see youtubes video compression struggle with the white noise

[Ncky]

Send old not working board to EEVBlog for inspection :D

You could use dust-off as freeze spray, just turn the bottle upside down

"I found your problem, " "Yeah what is it" "IT'S FUCKED"

[_waymin]

"I would say that is uhh... that's fucked."
Killed me.

Looks like the image quality on my old CRT.

Why are you saying obvishly?
Is it a local dialect?

[TinchoX]

This was interesting to watch!
I didn't know they still made Plasma TVs.

[DigBipper]

The way that TV glitched out kinda reminded me of when my GPU shit the bed midway through a video render... that was fun XDDD

[HonestLettuce]

have you tried turning it off and on again XD

[ezyto]

Why was this recommended to me and why am i still watching this?

[XxtrashcanXx]

some metal oxide surge protectors would of gone a long way.

That tiny regulator that you replaced was certainly not powering a big heatsunk IC! It was possibly powering just some of its I/O voltages, and likely GPIO falls off causing boot error or BOD prevents chip from starting when it's too low, or maybe it powers the NOR right near it that has a low enough logic threshold to interface with SoC directly, but needs higher voltage to actually operate. One of the big inductors presumably post buck converter with big banks of surface mount capacitors is likely what powers SoC's more predominantly used voltages, and it looks like a multi-voltage SoC, like separate core and RAM controller voltages.

The outputs on the left look like they might be LVDS, after all they come out in pairs. It also goes to an unpopulated test socket -that looks like 40-pin LVDS socket for dual-channel LCD panel.- NOPE that's just connector footprint reuse if at all, that is not the standard pinout.

I suspect that depending on what the input jellybeans on the right are, they might actually be the ones that failed, as there's quite a bit of them on the way to SoC, probably designed to lessen the impact if something goes wrong, and they would be first in line to fail. I'd have an urge to depopulate them on HDMI2 for curiosity, but then again, the display is repaired, of course better not to mess with it more.

have 2 plasma TVs. lightning struck nearby, lot of neighbors and myself suffered electronic fails.
each of the samsung plasmas were on a (cheap) power surge strip that did not work.
first tv --- only thing showing life is red LED standby light, and maybe some clicking when try to turn on.
second tv --- analog component works, but all HDMIs do not (dead), including where we have cast plugged in (cast doesn't work).
they are PN63C7000YF and PN63B550T2F --- if i were to attempt to replace what likely board(s) i would need, what would be your best guess to buy?
thanks for any and all.

I have the same TV lightning one day hit and it died. In my case nun of the ports work except the USB witch can still play USB media but everything else is dead. I'm not sure if that could be the same cheep that died or not.

You want to test the rf coils going to the hdmi port

I have a samsung pn51f4500bfxza and im having problems with it from a lightning strike. standby is giving 5.24, the ps on is 4.39, the vs on is 0. pulling my hair out trying to figure out whats the problem.

[enayes]

from the way it was flashing did u chek the caps the feed it?

[ecorp]

I'm curious, how much did you paid for the new board ?

Exactly the same thing happened to Acer PD525PW DLP projector I got for free (really crappy quality), if I connected it through VGA it looked like this, but if I connected it through S-Video, it was all right. So I didn't bother fixing it since it had no value, and used it with an old laptop with S-Video connecter. It had worked about 800 hours on the lamp before the failure happened, so my thought was burn the lamp and after it dies just scrape it. But after about 20-something hours it started to smell bad, like, I don't know how to describe it, sulphur-y burn, so I passed it to someone else for parts for approx. 20 bucks.
