Facing TV Problems? Ask a TV Technician.
Hello, My name is ***** ***** I'm an Independent Tech. Please send a reply back so that I know you're with me and can see my replies.
Thank you. Can you please tell me what you're referring to as "WHAT DO I CHECK AFTER RECEIVER"? What receiver do you mean?
Okay. What I need to know is this:
When you press power on the TV itself (not the remote), does the power light change as it should, and does the screen light up even for a second?
Okay I was asking if the screen lights up (backlights)?
No picture, but if you dim the lights in the room does the screen light up at all.
Okay, it's pretty important in troubleshooting to note.
This rules out the Mainboard and points to the power board. You have a multi-meter I would assume?
It's 5:20 pm where I'm at- I'm in the US. So when you get out of work I'll likely be sleeping. However if you know how to measure DC voltages (which it sounds like you do) then you will ground the black meter probe to the metal frame of the set, then set the meter to DC and probe the pins on the power supply board (voltages are stamped on the board) and see if the 5, 12 and 24 vdc outputs are present. If only the 5 is present- then you need to replace your mainboard. If the 5 and one other voltage are present- then replace the power board.
The chat stays open even once you rate- I can't close it and it's open for replies. So reply back when you can and when I see your reply, I will reply back- thanks!
You're welcome and sounds good.
