Re: Hitachi LE55A6R9A - No backlight
Ok, finally got around to testing the voltage at the LED connectors. I get a reading of 272 on the RED from the RED/WHITE pair. However, I am unable to get a reading of anything >1 on any of the other 3 wires. Am I doing something incorrectly with my multimeter or does this indicate a problem with the board? Also, I have not done anything with the backlight level....

Re: Hitachi LE55A6R9A - No backlight
Ok, so before I go tearing into the TV again, what are the possible causes here? If there is an open circuit, would that be due to a single bad LED strip? Or is there another cause for this type of issue? Just trying to determine what I'm up against......

Sorry for the confusion....Yes...I can see the picture when shining a flashlight thru the back.

Re: Hitachi LE55A6R9A - No backlight
Pardon me if this isn't proper forum etiquette to post this here...
I also have a Hitatchi LE55A6R9A wtih no video/backlight after possible power surge. Power light is on & TV passes flashlight test. All LED strips were replaced with new ones (from ShopJimmy) less than 90 days ago after i lost the backlights.
Surely the LED strips dont need to be replaced again....I was able to replace them myself without too much issue before. However, I dont have much experience testing components with a multimeter, so troubleshooting...
