Sharp LC-50LE442U does not turn on. RED standby LED is lit, when I try to turn it on, the LED turns green but screen stays black. LED then stays green, won't go back to red when turning off.


You cannot tell if capacitors are bad just by looking at them. they need to have a meter called an ESR meter to test them, I can tell you with almost certainty that it is a capacitor in the power supply that has failed. The whole board is Sharp 9JY0950CTN02000 Power Supply Board (09-50CTN020-00) LC-50LE440U LC-50LE442U

LC-40le550u no picture... green light on


if powers on and has no video and no audio could be the main board, but first try this :

take a flashlight, turns on the tv and try to "see" the image while light up the flashlight against the screen , if you "see" something you have a bad back light inverter board.

below the posible parts number :

MAIN BOARD : Sharp 9JY0140CTJ05100
POWER SUPPLY/ BACK LIGHT : Sharp 9JY0940CTJ05000

TRY TO LOOK FOR AT :

Sharp model lc-20sh1u won't turn on, just makes a clicking sound and indicator light flashes red.


The clicking sound may be a power relay coming on and then off--problem indicates a trouble in the main power supply.

THe problem is in the set top box. Or common called the tuner box. IT looses the 5 volts to the main display and thus the monitor will go into a shut down state. THESE boxes are factory repair only and must be sent off to repair.

Sharp lc-22sv6u won,t power on. no green light.


Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

LC-37BC6X sound but no picture


If the television back panel is close to a window or cold you need to heat the panel, I have used a blow dryer. Now I moved it to a warmer room and away from any drafts. No more problems
