Re: LC46XD1E repair
If I understand Sharp Tvs correctly, if there is an issue which forces it in to a power protect mode, turning it on and off 5 times or more will throw it in to a mode where the back light will not turn on, I had this with an old Sharp LCD and only entering the service menu would resolve it, of course I could not see this so the correct presses on the remote were needed. I'm sure if your just a little more patient some one will give you more clarity. -

The problem is that the power supply PSC 10189DM PKG1 does not release the current to the screen!Attached FilesComment

With set unplugged, Press Input and Ch - Hold both buttons and plug in keep holding buttons for a few seconds.

Re: LC46XD1E repair
When you connect the circuit the relay will pup without stooping and then the current Which goes to the red of the screen will not start, is there any replacement tools needed for this board so that the current goes to the screen?Attached FilesComment

Re: LC46XD1E repair
Did you try Alastair's suggestion? Note on some Sharp sets you need to unplug them, hold the buttons then plug them in; others, you need to turn them off using the "soft off" button (which should make the standby light go off), hold the buttons, then press the "soft off" button again (to turn it on into standby) then press the power button to turn it on. You need 3 hands...!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: LC46XD1E repair
There could be many reasons why this is not working.
You need to do things methodically. Check that PSU board where the leads go to the Mainboard.
One or two of those leads will be marked, 5V
Is that 5V present?
The Mainboard makes the PSU Turn On,--But only if the ever present 5V is actually supplied to the Mainboard in the first place!
I can make NO sense of your picture or the 82V you speak of.....TELEFIX

Re: LC46XD1E repair
Yes the 5 volts are present but the problem is with those 2 capacitor marked with "red circles on the picture" 1 capacitor have 100v but when they are active they releasing only 82v!Comment

Re: LC46XD1E repair
That is only a voltage rating that the component is designed to withstand. Theyc can use put less than 100V across them.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I acquired a free 50” TV. IT is a Sharp LC50LE752E. It does not show a picture and has no backlight, although the indicator light turns blue meaning it has turned on.
When power is plugged in, the indicator light will turn on blue, the backlight stays off and nothing is visible, even with a flashlight. When pressing the touch buttons on the tv nothing happens. When pressing buttons on the remote control the indicator light will blink indicating the IRsignal was received, but nothing happens.
When I hold the force-on-combination it will turn on. It then shows a perfect... -
I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent
I also have back when Light of America had these light bulbs available for yard lights
The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail
While the Lithonia lighting fixture has all most certain bulb failure
So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last
I have only had this light fixture for not more than a year if it... -
