Question about Sharp LC46SV50U - Lc46sv50u 46in Lcd Ccfl 60hz Tv

1 Answer

My sharp LC-46SV50U wont turn on

I rarely use this TV as it is my finished basement (climate Controlled with a De-humidifier running 8 out of 12 months of the year) went to turn it on, and nothing happened the Red LED was on the lower RH corner I power cycled the surge protector it was plugged into now it sits completely dead, no lights, sounds, noises, NOTHING. Anyone experienced this issue? in thinking bad power supply. The one thing about my situation is we had some strong storms come through a week ago, the TV is plugged into a surge protector that is plugged into a GFCI outlet. We did have power brown out a few times during the storm, and I am wondering if the lower voltage caused the issue.

Get the service manual and then open it up and do a voltage check on the 5v standby.

if it's not showing anything, then you need to hunt down if it's the ic, cap, or diode or a combination thereof.

Go to and get a universal stand. It attaches to the back of the TV just like a wall mount.

I don't have a manual and I can't get rid of CC

The first thing that you need to do is verify how you are connected. I could better troubleshoot your problem if I knew that so for now I can just give general advice. #1, What do you have connected to the unit?, are we dealing with coax cable? Antenna? or cable box/satellite box. If you have all except cable box, the cc function will be controlled by your sharp remote and if you press the cc button a number of times, you can turn it off. Everytime you press that button, it changes (ex. 1/4, 2/4, 3/4, 4/4, and OFF..which is what you want). You can press the DISPLAY button on your sharp remote to check the status of you cc. However if you do have a satellite/cable box, your cc is NOT being controlled by the tv, but is being controlled by your cable/satellite reciever and the settings need to be adjusted there. I recommend contacting your cable/satellite provider for assistance with turning it off within the cable/satellite box settigs. #2 There is a place on the web where you can find a manual for free that even sharp wont tell you . This is their canada website and the same manuals that are for the us models are here, it is all the same literature. hope i resolved your issue
