Re: E320-A0 - Power LED Fades, Sound, Picture (Without Backlight) LED Issue
Considering all I have is the main board and the led strips, no seperate driver, how would one test?

I tried all the points on the strip. I can not get below the dome without damaging it.Leave a comment:

I cant get any of the leds to light up with 3v 100ohm resistor supplied power

Seemed to go through. Will see if I get a response. Thank you.

In the mean time, Budm, is there any more on your question so I can continue to diagnose? (I am still looking for a 100ohm resistor that seems to have eluded me.)...Leave a comment:

Re: E320-A0 - Power LED Fades, Sound, Picture (Without Backlight) LED Issue
I believe the eeprom to be good, as I have all correct voltages, and led's out. I have replaced the main board with an "assumed bought good" board that came from a working busted panel tv to get the same issue.
using all the part numbers, not even shopjimmy came up with the strips.
how could the eeprom cause the led's to not function with correct voltage?

Correction,
The voltage is coming out of NEG on the end, so it appears to short to ground somewhere. (BAR One)Last edited by crepiduse; 04-22-2015, 03:09 PM.Leave a comment:

E320-A0 - Power LED Fades, Sound, Picture (Without Backlight) LED Issue
I have a E320-A0 that I am fairly certain is the backlight strips. All voltages are normal, and getting 33v to LED strips.
Now, on the main strip, input is 33v goes through 5 LEDs, out at the end is 9v.
The first strip doesnt even flicker. The second is very faintly flickering.
I am fairly certain its the LED strips. I can not find replacements anywhere, so is there a way to test this to the individual strips and individual leds? -
Re: vizio E320-A1 not working
Which EEPROM and is this the same as the E320-A0?
I have a E320-A0 with sound, no picture.Leave a comment:

Is tcon the only left scenario? I'm on limited income and don't want to spend anymore than I have to.Leave a comment:

Re: RCA 46" LCD Model: 46LA55R120Q - Symptom: Verticle Lines throughout entire displa
Ok... New board came in. The FRC came out of a TV that I was able to verify works.
The symptom is the same if not slightly worse. Still have the vertical lines.Leave a comment:

Thank you, Will order the FRC, and update when the FRC is installed.
Edit:
For future search, this is the FRC Part Number: RE3342B051-A1Last edited by crepiduse; 03-04-2014, 01:56 PM.Leave a comment:

and just to be sure, the FRC is the green board pictured above?Leave a comment:

If I replace the FRC is it likely to be damaged by a bad tcon?Leave a comment:

Thank you for the rapid response.... Didn't expect it and already went to take pics.
Would be a funny trick for there to be a bad plasma display.... Since its lcd.
