Sharp LC-60EQ10U Dark Screen

[JessJ]

Hello everyone. Glad to be a new member and looking forward to learning more.

I have this Sharp 60" TV. It powers on and the screen is dark. You can see the images moving so is the backlight the issue? Where do I start?

Thanks

Jess

Sounds like the backlights are not coming on. Have you removed the back yet?

Yea I have the back cover off.

The people on the board here need pictures of the back of the TV with all boards installed so we can see the layout and pictures of each individual board in case we have to help trace circuits. Please be sure they are clear and well-focused.

After posting the pictures I also recommend:

At the top of the "Troubleshooting TV's and Video Sources" page are items marked "Sticky". Please take the time to read these before attempting any troubleshooting on your own. Contained in these "Stickys" are basic information that will help you learn how to troubleshoot safely and excellent information from highly knowledgeable and professional electronics technicians who put those there to help you know how to get started.

Be patient, people in here have lives they live outside of the forum but are truly dedicated to helping people with good information when they can. Troubleshooting through a forum isn't the fastest way to go, but if you have never troubleshot a TV this is the place to glean good information from helpful, patient people. Trust me, they had to be patient when I showed up!

When troubleshooting with a meter, BE PRECISE, FOCUS on the job in front of you and BE CAREFUL! There is 400V plus inside the TV and that will kill you. Another thing you can trust me on....imprecise or sloppy motions while measuring voltages will lead to the destruction of other components. I have stories.............

Read this thread to see how to check the Voltages at the LED connector and also how to check and see if the backlights will come on or not.

Bud I read through it. I don't know what a T-con board is etc. I am more mechanical savvy than electrical boards. Where should I start?

Jess, your description of the fault is imprecise, post a picture of the defect, or if the image is completely black from a distance of 1m or in a dark room then continue to troubleshoot backlight.

This is a definite backlight issue. The difficulty here is really handling the thin glass screen They break easily if handled badly. You would need vacuum cups to pick up the fragile glass screen.

Re: Sharp LC-60EQ10U Dark Screen

these pictures don't align with your first post about "dark picture" as these clearly show the menu along with "picture static" (no input). Please explain. Further, based on the distortion along the top left side of the menu, it would appear that you have a panel problem but it is difficult to say for sure without a proper input signal and explanation.

Re: Sharp LC-60EQ10U Dark Screen

if you have a big box full of things put it behind the tv as a stand and do some better pictures, anyway it seems to me the common panel fault that is fixable with piece of adhesive tape, second detach one at a time the lvds ribbons that outputs from the tcon and see with which one the half picture is perfect.

Re: Sharp LC-60EQ10U Dark Screen

Ok I will get those. Budwich, The way I described the issue was the way it was when I got the TV. After taking the back panel off, tipping it up and starting it, this is what it looked like. Totally different I agree. I will get my wife to hold it up for better pics.

Re: Sharp LC-60EQ10U Dark Screen

:-( no problem.... but that does sound good. As suggested, likely a panel issue but potentially it can be save by a couple of "techiniques"... but it really depends on you providing good pictures of the display with a good knowable picture (test signal).

Re: Sharp LC-60EQ10U Dark Screen

Ok sorry for the wait guys. Family stuff so my tv got put on a side burner

Here are the pics of it. I had it hooked to a VCR to get some video pics. I did not have a video playing but you can see what its doing.
