Facing TV Problems? Ask a TV Technician.
Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.
What video source/ device you were trying to hook into HDMI input of TV?
Thanks for the info.
Please disconnect Directv box HDMI cable from DVD player and connect only DVD player HDMI cable into TV, do you still get spark?
Also, does TV display DVD player picture?
I guess my reply wasn't clear, do the HDMI inputs of TV still working?
Correct, we both aren't on same page so let me opt out to repost the question and hopefully another expert will soon respond to assist you further.
Hello, My name is ***** ***** I'm a different expert. I understand you're looking to fix the TV's- but you never stated exactly what the TV's are doing or not doing right now. Are there any signs of life on either of them (Power Light, etc.)?
The spark at the HDMI ports could have caused several possible things- Mainboard or Power Board failure, as the HDMI ports on the Mainboard run off of 5 volts from the power board, so simply asking how to fix them, depends on what exactly the symptoms are. Let me know and we can proceed.

Okay, I'm not asking about the DirecTv connection. I am asking this:
Is the TV's power light lit, blinking or completely out?
Let me try again to help you, please provide the specific info only that I request. Please forget Directv box and its connection and focus on TV only.
So far we got to know, LG TV light stays On but screen stays dark.
How about Sony TV, what does the power light do when you turn On the TV.
OK, and when Sony logo fades out, does the power light stay On or start flashing in specific pattern like 5 blinks, pauses and again 5 blinks etc?
OK, it seems electric spark took main boards of both TV and replacement of main board will help to resolve the issue, please check following link to view LG TV main board image and part number info and ask the supplier if they can provide as currently it is out of stock..
and following link shows Sony main board (BAL Board) image and price info..
I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
