Re: Toshiba LED tv 46SL417U What does 3 blinking green lites mean
I finally found this board on ebay about a month. Difficult to find. It is working ok now. I have a UPS on it as I read that the EPROM can get corrupted if the power blips. Have not compare values yet but I'm looking to see if I could reload the software but afraid of damaging my new replaced board. No one seems to be able to get this board. Only if you are lucky to find one on off a cracked tv.

Re: Toshiba LED tv 46SL417U What does 3 blinking green lites mean
removing the 24v made no different, removing the 5v the tv would not come on, any one have any suggestionsLeave a comment:

Re: Toshiba LED tv 46SL417U What does 3 blinking green lites mean
I talked to a tech he suggested removing the 24v feeding the main/seine board and seeing if the blinkling lights sequence changes.Leave a comment:

Re: Toshiba LED tv 46SL417U What does 3 blinking green lites mean
I tried flashing the firmwave with a thumbdrive, no luck
42SL417U
46SL417U
55SL417U
These units seem to have the same boards, google them all, no luck, getting the proper voltage 12,24 and 5 v from the power supply.Sounds like the processor on the main board controls everything. Sound like a common problem but no cures out there on the web,other than replacing the whole board, I wonder what's taking these boards out of service.Last edited by mark090; 05-18-2013, 05:18 PM.Leave a comment:

Re: Toshiba LED tv 46SL417U What does 3 blinking green lites mean
Intimidating board, I have read in another post maybe flashing the card, ram gets corrupted but no sure it was for this unit. Enjoy troubleshooting so not a burden, rather fix it rather than just changing boards. But this board is complicated and I might be fooling myself to repair but would like to isolate to this board only and then purchase it. Don't won't to end up purchasing alot of boards. Thanks for working with meLeave a comment:

Re: Toshiba LED tv 46SL417U What does 3 blinking green lites mean
Yes I have seen this tread, hoping someone would know what part might been bad on that board or what voltages to look for. I have check all the caps and they are ok,checked diodes ok on power supply. Would like to isolate. ThanksLeave a comment:

Not the same IC, it is a 10 pin IC chip, with an ohm meter no shorts or open.
This is the power supply for my 46 in, different than the 75002913.
