"Never disconnect or connect any cables with the power connected / on."
Kinda what I thought but wanted to be sure that wasn't something you wanted me to do.

Re: Sharp LC-60LE832U
Do you mean disconnecting and reconnecting the flat cables going the bottom edge of the screen while the power is on Budwich?
Have not found the right combination of keys yet Mmartell.
FYI, I have noticed a faint light background on the left side of the screen that just flashes when I power on the TV along with the quickly disappearing HDMI/1080 at the top right. The glow is very faint and cannot see if the room is not completely dark.Leave a comment:

Re: Sharp LC-60LE832U
The screen does light up momentarily when powered on and the HDMI/1080 shows up during that brief time then all goes black again. Does not last more than a second.
I haven't found any combination that will give me the "K" screen....Leave a comment:

Re: Sharp LC-60LE832U
Will do, thanks,
With the power indicator on constant, pushing menu does not do anything.Leave a comment:

Budwich?
Are you waiting on me to do something?Leave a comment:

Re: Sharp LC-60LE832U
"have you tried hitting the menu button with red light on solid?"?
The only red light I see is on the Video Board. It blinks when the power is turned on and goes out with a click shortly after the power is turned off.Leave a comment:

Re: Sharp LC-60LE832U
power on: 3 & 4 touching negative multi-meter probe and red to air. Meter just keeps climbing as if nothing is touching either probe.
Power on: 13 = 3.32vLeave a comment:

Re: Sharp LC-60LE832U
Sorry for the confusion, I did not check 3 & 4 because I thought they were ground and didn't matter. Will get the readings as soon as I can get some help.
Thanks

Re: Sharp LC-60LE832U
Will do when I get some help to lay it back down so I can turn the board over and test.
FYI, I used the chassis for ground on the last reading with the power on.Leave a comment:

Okay, no image with a flashlight.Leave a comment:

Re: Sharp LC-60LE832U
I don't know what the flashlight test is?
I did notice the entire screen kind of flickers once shortly after the power button is pushed and the HDMI/1080 pops up in the upper right hand corner. That lasts less than a second and goes back black. Power light stay on and steady and will power off and on fine until the tv is unplugged from the wall then I have to reset it again.
Oh, one other thing I have noticed is there is a tiny red blinking light (diode I guess), sort of in the middle of the video board, when the tv is on.Leave a comment:

Re: Sharp LC-60LE832U
Some more info. Found that I could use the power button to power off and on without long/short blink of the power indicator until I disconnected the power; I then had to do the Vol-/Cha+/Pwr button thingy again.
Tried swapping the PB out with the original; same as the new. Tried swapping out the original Video Board; same as the new.
So at least I get consistent reactions from both new and old boards?
The screen has remained blank throughout but we did notice a flash of the "HDMI 1080" in the upper right corner...Leave a comment:

Re: Sharp LC-60LE832U
BTW, I do have power on now but no screen activity.
When I powered it off and back on I got the long/short blink. Did the Vol-/Cha+/Pwr buttons again and got a steady power light again with no screen activity.Last edited by RickSinGA; 08-07-2017, 09:05 AM.Leave a comment:

Re: Sharp LC-60LE832U
Backed up and mounted toe base and stood the panel up where I could actyually see the power buttons etc.
Did the V_, Cha+ and Power. Power light now was constant. Took these readings.

Re: Sharp LC-60LE832U
Yes, all connected. Remember that I have no way of powering it on. These reading are with the TV plugged into a wall receptical.

Re: Sharp LC-60LE832U
Yes, this is with the new PB and MB installed.
This is just plain crazy, I am getting different numbers now when I use the chassis as a ground vs the pins #3&4? Appears as I now have power although negative on most pins that used to be zero including +0.1mv on #13.
Have to wait on a helper to write down the readings as I probe the pins, will be later today.
Am I doing something wrong?
Thanks for the help.Leave a comment:

Re: Sharp LC-60LE832U
Here is where I am at as of now.
Replaced Power Board; nothing changed?
Replaced Main Board; nothing changed?
Still one long and one short blink of the power light when pluged into power. Neither TV nor remote works for power on or shortcut to codes. Screen is black, no indication of any activity.
Can anyone give me some direction please?
Thanks
