@MrIshor - This could be one of a few things. Unplug TV for 30 seconds. Plug in TV if it comes on by itself turn it off and on immediately. If it does not come on just turn it on, then off then back on fast as you can, Press and hold the up arrow on the remote and press and release power button on the TV. release the up arrow see if the TV resets. should come on to ch2 and then the language set up option. See next comment for more info!

Hello
I have a Cost Co Sharp model LC-80LE642U and I am replacing both RUNTKB096WJQZ and DKEYMF953FM06 but am unable to remove the back cover. Now before you say it I have removed all visible screws and I can get the bottom edge off an inch or so but I am not able to get the side edges even started. I've exerted a reasonable amount of effort (pressure) at the bottom of both sides with no success. Any pointers or specific documents referring to this model and removing the back? I have had no luck finding any docs on repairing this model. I've only found the shopjimmy youtube videos. I don't want to break anything in the process of removing the back. Thanks for any help beforehand.

Hi Jimmy, I have an LC70LE650U unit and all of a sudden gets a discoloration mainly on the right side of the screen and this is going on for all inputs. Would suggest replacing the main board or power supply/backlight inverter boards? Thanks much.

Hi Jimmy, what is the inverter board part number for Sharp TV model LC-50LB370U. Thanks.

[pgluckydog]

Jimmy, I have an LC80ue30u. The TV locked up when I went to pull up the smart menu. I pulled the cord to get it to turn off. Some hours later, when I tried to turn it on again, I noticed the power light flashing, one long and then short blink. I tried the power plug/button reset numerous times.. All I get is the Sharp logo for a few seconds and then clicks right back off. The TV is less than two years old. Do you think this is a power board or main board? I didnt see any burnt circuits or bulging capacitors. Any help appreciated.

Hi, I have problem with Sony Bravia KDL55EX720 model tv. When turned on, it lights up and displays picture for only about 3 seconds and goes off. It has red light blinking for 7 or 8 times. I learn that, this could be power supply board of inverter board. I am an electronic tecnician but have not worked with big tvs. Can i replace the defective boards. Would they be available? Please suggest. Ishor

I just had my Sharp TV LC-60LE640U busted. It seems like a backlight issue, before i can see the picture got darker literally above the V lighting logo. Then yesterday, the screen would not come up anymore, it stays black, and i can see the lighting V coming on and off. It will blink 1 quick and 1 longer blink. Any idea on what to replace and do you have parts?

I've got a Sharp LC-60LE830U.  My blink code is one short one long and from the service manual it says it's Inverter/Lamp system failure.  Any suggestions on how I go about fixing this?  I was hoping it would just be a power supply issue where I could install a new one, but doesn't look like it.

Hi I have this power board and found D7128 damage and the number can't be read did any one have this information be useful to find a replacement thanks

[francisek]

I own a Sharp Aquos 60" television model #LC-60LE831U.  The bottom center power light "v" shaped clear light is blinking. It blinks twice, then pause, then 3 times. I do not have a picture, just a black screen.  I bought the television in 2011 so it is only 4-5 yrs old.  From this description, do you think it is the back light? thank you

I have a sharp lc-50Lb261. The sound works, but the picture does not. If I shine a flashlight at an angle, I can see a very faint picture of the video.
