Re: Hitachi LE49S508
I'm going to check them and keep the good ones in a box somewhere for future use. I wanted to use this tv for learning a bit more and I think I learned a fair bit reading and following this thread. there is no bezel on the tv, the plastics are broken, so I think I will salvage the good light strings and the boards and trash the rest.
Thanks for helping, I just needed that one "I think it may be the led" to push me to go that far.
Again thank you for the help, look forward to seeing you around the forums.

Re: Hitachi LE49S508
So I tested the one that looked dead and it was, the rest in that string worked fine..Leave a comment:

Re: Hitachi LE49S508
Was pretty easy to spot the dead one as soon as I opened it up. If one led is dead it renders the rest useless, correct?Leave a comment:

Re: Hitachi LE49S508
I was thinking the same thing, I got the tv for free and I have some free time so I might just break it down and test the leds to kill some time.Leave a comment:

Re: Hitachi LE49S508
I have not, I will do it right now.. I have followed every other step in this thread and everything measured up to what budm said it should have been.
If I remove the connector I get 125.6vdc at led1+ but 0 on the rest. If I read it as I turn the tv on it jumps from 0 to 199vdc and after about 1 second it falls back to 125vdc again.Leave a comment:

Re: Hitachi LE49S508
So for some odd reason todays voltages changed only for the LED's.
CN4
LED 1+ - 124vDC
LED 2+ - 95VDC
LED 3+ - 66VDC
LED 4+ - 40VDC
LED 5+ - 14VDC
Could have been my DMM acting up.Leave a comment:
