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

Sony KDF-46E2000 - Screen Goes Blank


You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

LC-32SB24U LCD HDTV... Brand new, just out of box. Turn on, goes to language menu for about 1 second max,too fast to adjust, then screen goes black and little green led power light starts to blink. And...


Good Day, texxastam;

Do this:

1. UNPLUG TV
2. HOLD IN VOLUME DOWN &INPUT buttons on TV
3. Plug in the TV. (the TV will turn itself on).
4. A blue "K" should now be showing on the TV screen, release the buttons.
5. Press and release the VOLUME DOWN & CHANNEL DOWN buttons simultaneously on the TV. (A blue service menu will appear on the screen).
6. Using the remote, press the DOWN SELECT button once. (The highlighted line should read INDUSTRY INT (+CAUSE) OFF
7. Using the remote, press VOLUME UP once (OFF changes to ON).
8. Press ENTER. After a few seconds the screen turns green and shows - Industry INIT success - at the top of the screen.
9. Unplug the AC cord for 10 seconds then plug back in.

Good Luck, big IRISH.

PS; I did not make this up... it's from SHARP> again good luck...you may have to do this several times....too...get the timming down.
