Re: Sharp LC 46D64U Screen flashes then dies
Nope - it won't take it. Too big.
Lemmie do some leg work. I am pretty much a leech right now so a little work on my part is warranted.
I can post specific screen prints when we start to get the cross hairs on the target.
Again, thanks!

It's 28MB. Is that too big to upload here?Leave a comment:

Re: Sharp LC 46D64U Screen flashes then dies
No issues with the site. I did not read the sponsored ads close enough and installed some swanky PDF interface file that just loaded some needless stuff which I deleted along with the swanky program.
I have the manual in pdf form. Gracias.Leave a comment:

Vince and all.
Thanks.
Sorry for the impatience. Let me look over this manual and come back with better questions. If I find the problem I will report.Leave a comment:

Attempting
Got it. I got sucked into the sponsored links. But, hey, I have Weather Bug now. :-)
Thank you very much....Last edited by Bob Kontak; 12-06-2013, 03:34 PM.Leave a comment:

Oh - as in on the screen - when you go into service mode?
Have not tried that yet, if so, given the short time screen can be observed.Leave a comment:

Re: Sharp LC 46D64U Screen flashes then dies
Error output is a green flashing power light on front. Once per second. This is when the tv tries to start, screen flickers and it shuts itself off with a click. It does not always do this. Sometimes it does not click off.
I believe the every second blink means backlight/inverter issue.Leave a comment:

Re: Sharp LC 46D64U Screen flashes then dies
From main power board there is one set of wires that feeds the left set of inverters and one set of wires that feed the right set of inverters.
Their voltage appears to be ok.
From the separate main control board, The LB connector mentioned, two wires of four feed 3.28V to the master inverter board. Is this enough power? Is there a minimum it requires? If so, say 12v, I need to look upstream vs downstream.Leave a comment:

There are letters "LB" on main board is this BL?...Leave a comment:

Re: Sharp LC 46D64U Screen flashes then dies
I am assuming the two wires that I found voltage from the main board to the master inverter are the what turn the backlights on.
Would there be an indication on the main board of what BL on/off is?
Of the four wires (main to inverter), one grounds to the case, two have voltage, and the fourth, I find no voltage or ground....Leave a comment:

No argument there. "A" beer is the key, for me at least. Three beers and I may change out antifreeze in a car. Three beers, I don't repair brakes. Old enough and have learned the hard way.
There is one cluster of wires that lead to the master inverter board from the main board. Four wires in total. One black, three grey.
The black wire and one of the grey wires feed 3.28 V to the inverter board. When I press the primary on/off button to on (with the DVD player on and playing), It takes a few seconds...Last edited by Bob Kontak; 12-05-2013, 06:55 PM.Leave a comment:

Outstanding.
Let me get my reading glasses on, pop a beer and get to business.

Re: Sharp LC 46D64U Screen flashes then dies
Ok - I believe BL means black? I think I am understanding you.
The number one inverter board has an input from the main board. The others don't. Plus number one is larger and has a few more gizmos on it than the other three.
So you want me to check the black line voltage (from main board) that feeds the master board and then the black line that feeds the slave board from the master for voltage fluctuation or anomolies?
Otherwise advise.
Many thanks. Will report back in a few.Leave a comment:

Drops a couple hundredths of a volt when flickering but baseline is 11.67.Leave a comment:

Re: Sharp LC 46D64U Screen flashes then dies
60 volts steady before flickering. During flickering a range of 59.1 to 60.3.Leave a comment:

Re: Sharp LC 46D64U Screen flashes then dies
OK - Plugged in a DVD and I have audio and you can see the video just fine when the bulbs try to start. On average about a dozen bulb flickers then screen goes dark but audio remains. If I do this when the tv has sat unplugged for ten minutes, it will shut off after ten seconds. I do not have to reset it. I just turn it back on and it goes thru the same routine but does not shut itself off.
Bulbs appear to be ok.

Sharp LC 46D64U Screen flashes then dies
First post here. Howdy all.
You may want to skip to the highlighted "Post Rambling" section. Perhaps less is more.
Initial symptom - no action but constant 1 second interval of blinking green power light.
Found reset sequence and green power light was constant for maybe 10 seconds then set would "click" off. However, before dying, screen would flash about 6-8 times. Fairly uniform.
Disconnected 60V/12 V power leads to the inverter boards and using reset power would stay on. Hit the on/off button, set would shut down...
