The Classroom TV is hooked up to various PCs.
|
||||
|
||||
Once we repair'd it by exhaustively testing each LED on the device and
|
||||
replacing the broken one.
|
||||
|
||||
## The TV
|
||||
|
||||
The current TV is a 60-inch **Sharp Aquos LC-60LE920UN**.
|
||||
|
||||
Manual is available at
|
||||
<http://files.sharpusa.com/Downloads/ForHome/HomeEntertainment/LCDTVs/Manuals/tel_man_LC52_60LE920UN.pdf>
|
||||

|
||||
|
||||
It should be labeled appropriately for ease of use. There is a remote
|
||||
control. If the screen won't come on and the little LED logo at the
|
||||
bottom middle blinks instead of coming on solid, reset according to
|
||||
instructions on the device.
|
||||
|
||||
Sometimes when there's a problem, it displays a constant small blue box
|
||||
which reads **\[K\] 60LE810UN** which the careful reader will note looks
|
||||
remarkably like a model number...
|
||||
|
||||
### Resetting the TV
|
||||
|
||||
<http://www.fixya.com/support/t17617780-60_sharp_aquos_power_indicator_flashing>
|
||||
|
||||
POWER LIGHT FLASHES ONE SHORT AND ONE LONG FLASH.
|
||||
|
||||
What is the problem? THE PROBLEM IS THAT ONE OF THE LED's STRIPS IS BAD!
|
||||
|
||||
SHARP AQUOS LC60LE810UN RESET INSTRUCTIONS
|
||||
|
||||
` 1. Plug in TV to electric current First then wait until LED start flashing.`
|
||||
` 2. Press Volume DOWN [ - ] HOLD BUTTON.`
|
||||
` 3. Press Channel UP [ ^ ] HOLD BUTTON.`
|
||||
` 4. Press Power [ (') ] HOLD ALL three buttons until LED stops flashing and then release.`
|
||||
|
||||
This will reset the TV in order to fix the problem.
|
||||
|
||||
THE FIX IS TO REPLACE ONE OF THE LED's. You need to open the back of the
|
||||
TV and you will also need to remove the front cover and panel to get to
|
||||
the LEDs. The TV will need to be placed facedown and on the backside.
|
||||
This is a 2 person job to turn the TV on its sides. Be careful with the
|
||||
white computer connectors (wide white strip) at the base of the TV where
|
||||
the TV stand sits. You will need to disconnect this in order to get to
|
||||
the LED's.
|
||||
|
||||
Once you have the LED's exposed, you will need to unplug one by one by
|
||||
placing the new strip next to it until the unit turns on. You will have
|
||||
to use the RESET procedure above if the Power lite flashes. The Power
|
||||
lite MUST BE ON SOLID - no blinking in order to test the strips. The
|
||||
LED's will flash, but still one of them will be burned. Even if you
|
||||
stare and all the strip light-up, you will still need to check
|
||||
one-by-one!
|
||||
|
||||
Once the TV lights up, your face will also light up with joy! Put
|
||||
everything back together and you are set. If you need the complete
|
||||
instructions which come from Sharp as to how to disassemble the unit,
|
||||
please send me an e-mail to LGTR61@YAHOO.ES. Please note I don't check
|
||||
this address daily, so a few days wait may take for you to receive the
|
||||
instructions.
|
||||
|
||||
Where can you buy the LED's - try searching Yahoo.com or Google.com for
|
||||
resellers.

No POWER
|
||||
|
||||
How many times does the POWER led flash per second? (Dont worry about
|
||||
the OPC).
|
||||
|
||||
` * 1x (steady constant blink) = Lamps or inverters`
|
||||
` * 2x = Power Supply`
|
||||
` * 3x = Main Unit`
|
||||
|
||||
If i am reading it correctly, looks like the POWER led is flashing 2x,
|
||||
which means it is a power supply failure. Either way, your TV needs to
|
||||
have a board replaced, there isn't anything you can do to fix it
|
||||
yourself. Try locating your local sharp authorized service center to
|
||||
repair your TV (1-800-237-4277)
