Re: Insignia 42" lcd 120HZ loses picture not sound.

I have similar problem with 50" Insignia NS PDP42. Have great sound, but no picture. Already changed out control board, but still no picture. Searched web and determined tv is LCD. I just don't know which of the boards is the inverter board. YouTube video of LG set said there are master and slave inverter boards. Are you able to help me identify the inverter board(s)? Also, are they soldered or just clip connections?

Welcome to our community.  It's never a fun experience to discover a glitch with a piece of technology you own, especially with something so large and often-used as a TV.


By disassembling the TV and performing any repairs on your own, you'd be voiding the manufacturer warranty on your TV and any Geek Squad Protection (GSP) plan you may have purchased.  I'd recommend scheduling a service appointment with Geek Squad if you haven't already so we can send out a technician to take a look at your product and determine what options we may have to proceed.
