I was able to turn it back on, but I immediately noticed that there was no blue in the picture. I've seen a few accounts online of LEDs dying in these TVs, so I figure that's what's going on in my case. ShopJimmy sells the LEDS for about $70 each, which is great. I'm sure I can do the replacement, but I wanted to check here first to see if anyone has done an LED replacement on this TV and how difficult it was. Also, is there anything else that might cause one LED to go out besides the LED itself? I don't want to get into a money pit situation here. I know the TV is getting old, but if I can fully repair it for just $70 I'd be crazy not to.
Hi, having picture without blue is normally the blue LED but you described other things that makes me wonder.
Before you order a blue LED, make sure yours is bad.
It could be your LED Driver board or something else.
Slide the Light Engine out a few inches and disconnect the blue and white cable from the blue LED.
Take a good 9 volt battery and touch it to the terminals of the LED.
The + side of battery should go on the right terminal of LED, the one that had white wire on it.
You will see a small blue dot in the middle of lens if LED is working.
It is not bright so you need to get so you can actually see middle of lens.
If it is not working then you can feel safe ordering one, if not get back to me and we can figure out what it is.
I just looked and Jimmy does not have it in stock, he has not had them in a long time.
You can look me up on eBay if you need one but I only have one left right now.
