I have a sharp LC-37D40U that will not power on. The power light blinks 1 time every second. I held the input and volume - button while plugging the TV on and the TV cuts on and then cuts right back off,...


OK if you have blinking red light.

Try to open the cover then disconnect the inverter board after that try to power it on again..

If the light stays in blue (LIT) and of course you don't have picture or backlight you have faulty inverter board that need to be replace.

I have a Sony 26 inch Bravia LCD tv model KDL-V26XBR1.It has thin vertical black and yellow lines about an inch apart across the whole display. Not noticeable from a distance but really see them up...


Well if the panel is bad it would not clear up in any situation, so its not the panel. most likely the t-con board or just poor connections inside. Julio Millenium TV in Las Vegas.

What kind of connections are you using?

If component (red, green, blue) double check to make sure they are seated properly. I'm thinking it sounds like the blue one got loose.

Vertical line


Sorry, you have a defective LCD panel. If your TV is still under warranty, contact Sharp to get the TV exchanged. Otherwise, LCD panels cost more than the TV is worth.

Blue horizontal and vertical lines


We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.
