For some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

SOURCE: How do I fix my Sharp tv model LC-42D62U? On the tv screen now shows horizontal lines with repeating ghost images.

Hi Paul,
The horizontal lines on the screen are virtually NEVER caused by a bad T-con board. These horizontal lines indicate a defective LCD panel (screen). The Screen has small ICs that become defective overtime and that it isn't fixable unless replacing the entire screen.

Lcd tv screen goes black after a few seconds but sound still plays. The flashlight test will show the image for a short period of time but then it goes away and is completely black.


Hello... It sounds like you have a backlight failure, and the image going away during the flashlight test is due to the TV going into "Protection" mode. A service technician may be able to go into the service menu and clear the lamp error codes and get the TV working, or it may need the backlights replaced. I hope this helps...

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 :

or ebay

thanks

My tv sound is working but there is no picture can u please help thanks


With the tv on place a bright flashlight against the screen. Look for moving image around the flashlight. This show an image is getting to the screen but you need a back light to see it.

For an LCD tv you need to replace the back light inverter board.
Since you did not give a make and model I can not help locate the board. You can do it.
