Re: Toshiba 50L4300U Backlight
Yep I did. By replacing the bad strips everything was fixed. I was only able to get a full set so now I have many I did not use. Do you know which strips you need?

Re: Toshiba 50L4300U Backlight
So the first leg which is the top two sets and the bottom set all appear good.
The second leg however is bad. I tested as individual strips.
L1: All good > R1: 1 bad LED
L2: all bad > R2: All good
L2: had 2 bad LEDs > R2: 1 bad LED
Is that many bad LEDs common? Should I just get a set of strips? Should I replace all of them if others are soon to follow? (Why only the second leg? Power board surge or something?)Leave a comment:

Re: Toshiba 50L4300U Backlight
Checked the voltages and it does appear to be the LEDs. I took the diffuser out and did a power on test and the center bars don't flash, just the top and bottom ones. Do you guys suggest a stack method or just new strips?Leave a comment:

Toshiba 50L4300U Backlight
The backlight flashes very quickly on power up but that's it. Can see the menu with light. This unit doesn't have an inverter board so is it the main power board? Or could it all flash quickly because the feedback/return wires are indicating a faulty led and is turning off?... -

I was referred to the forums for tech assistance and I gotta say I'm excited to see how much is available on here. Very nice...Leave a comment:
