NEC 507Q backlights

[handsworth]

I have a chance to buy 2 of these tvs with bad backlights, however I cannot find any information on the parts. Thought I looked everywhere. Its a commercial grade 4K tv. Really would like to fix these. Anyone know what lights go in this tv?

Re: NEC 507Q backlights

Are you sure that the LED backlights are bad? Did you do any Voltage measurement?
What is the LCD panel model number?

Sorry Budm, I dont have any of that info. I can get both for $25 ea and will take that chance. Seller says both flicker, so I'll take his word. They are built on the Vizio framework such as E50-C1. Those boards look very similar, but a close up is not available to me.

The LCD panel is made by other OEM not by VIZIO, they may even use different panel for the same model
