Question about Sharp LC-70LE847U 70 inch 240hz Wifi AQUOS 3D LED TV [LC-60LE847U]

Open Question

I have a sharp LC-70le847u and it will no longer show any kind of video from any ports (hdmi, internal YouTube etc..). All menus and on screen displays are working fine as is sound. Any ideas?

I have tried all of the HDMI ports with different cables and sources. When I select any of the built in internet streaming apps, everything looks great until I try to play any videos. The screen goes solid color, with the on screen display text and controls looking fine. Sound works as well.

This unit has a chronic problem with the insulator material used on the heat sink on the ic's on the AV Bd. The unit must be disassembled and the AV bd. removed. The insulation on especially IC 2502 breaks down and must be cleaned off of the bd. and the ic and new insulator part # PSPAZA663WJKZ must be ordered and used as the insulator pad. If you send me an email to [email protected] I can send you the copy of the Sharp technical bulletin LCDTV-194.

I too went through this problem.

Step 1 - Plug in your "composite" cables and the HDMI cable to the PS3. Obviously, the "composite" cable are the ones that came with the system. You need to start with them as the default connector.

Step 2 - After connecting the "composite" cable and the HDMI cable to the PS3, connect the other ends to your TV.

Step 3 - Power on your PS3

Step 4 - Select display settings-->video output settings

Step 5 - Change from the current video cables to HDMI. (Your tv has different inputs. When you switch to HDMI in the PS3, you will have to switch your TV to the HDMI input that it is connected to, to get a picture)

Step 6 - Be quick, the PS3 will display a "test" for 30 seconds. You need to switch your tv to the correct HDMI input and press "X" on your controller to accept the change.

Let me know how this works for you.

SOURCE: Sharp Aquos LC-46d65U HDMI connect

First off a little tip that manufacturers don't tell you is that you HAVE to TURN OFF the POWER to ANY UNITS that you are Connecting to via HDMI!!!!!!! If not you can short out the Inputs!!!!!!!! HDMI is usually Automatic, But sometimes you need to go into the Menus on all Devices to the HDMI section and write down their settings and compare them. Any definition that you are not sure of check the Manual or Google it! Match all the Settings (there won't be Much!) Hopefully the Inputs were not Damaged it only takes one time to short it out and then the Repairman makes a few bucks! Good Luck!

GOOD NEWS - - According to the Sharp Technician I just spoke with a "Service Bulletin" went out to all their techs about the sound issue on these Sharp Aquos. I'm having the exact same sound probem and I'm in the process of having the technician come out at no charge so call the number given in Solution #6 and #9 (1-800-237-4277) and keep pressing #1 until you get a technician. Have your serial number ready and they will need your name, address and telephone #. They will then give you a case number and transfer you to dispatch (which closes at 5pm central). Thanks everyone for your help and posts - you made our day!!!
BTW - We also have the problem of the TV turning on and off by itself but the technician said they had not received a service bulletin about that yet.

How do i get the netflix app on my soniq tv please

That really depends. Just saying you have a Soniq TV is not much help because the different models have different capabilities. Is it a "Smart TV", if not does it have a HDMI port ? If not, does it have a DVI or VGA port. In order to install an app on the TV, it needs to be a smart TV, if not you can do it using a Chromecast or Roku device plugged into a HDMI port or a computer connected to either a HDMI, DVI or VGA port.

How do I hook up a roku stick?

I am guessing you mean the HDMI connector type Roku?

You simply plug the Roku into a free HDMI port on your TV, then switch your TV input to the proper HDMI selection, then start your setup. I believe this also needs to be plugged into the wall for power as HDMI does not supply power.

If you have an iPhone or other similar devices, you can download the ROKU app to control the device.

did you change the input source on the TV. What HDMI input did you plug into HDMI1 HDMI2 HDMI3 ? The input source has to match the port you put the hdmi cable into on the TV.
If no HDMI output on your media player use an adapter RCA to HDMI adapter. Here is an example of such a device

Can i watch netflix on my KDL-32EX524 UKA bravia tv?

To watch Netflix you need a (Netflix subscription of course) and a Smart TV with the Netflix app running or if you have an older TV you will need a streaming device like Amazon Fire TV
which plugs into your HDMI port to access Netflix via a wireless internet connection. The setup is pretty easy. Hope this is helpful.

Help me see my Netflix on my TV

Acquire a streaming internet player at a retail store or online. Streaming internet players allow you to stream movies and tv shows from Netflix, videos from YouTube, and music from Pandora, among other options. Different streaming internet players include, but are not limited to:
  • Apple TV
  • Roku
  • Boxee
  • Sony Streaming Player
Plug the player into its outlet. Power it up in order to hook it up with your TV and get it connected to the internet.
Connect your streaming internet player to your TV. There are several different ways to do this:
  • Connect with an HDMI cable. If you have an HDTV, you'll probably want to make use of that sparkling resolution by purchasing an HDMI cable and hooking the cable both into your player and the back of the TV.
  • Connect with a standard A/V cable if you don't have HDTV. Match up the yellow/red/white ports on the back of your TV to the video and audio cables.
Connect to your network. After turning on your streaming internet player, you'll want to connect to the internet. Most streaming internet players nowadays come with wireless internet setup, meaning you don't have to go through the hassle of plugging cables in everywhere in order to get a signal. Simply type in your internet name and password into the guided setup when you turn on your device.
  • If you don't have wireless internet capabilities, you're going to most likely connect one end of an Ethernet cable into the back of your streaming internet player, and the other end into an open Ethernet port on your router.
Finalize your setup. You've got power to your streaming player, you've got it connected to your TV, and you have internet. Consider a few other options before you start watching Netflix from the pleasure of your couch instead of your PC screen.
  • Download any of the latest software offered by the streaming internet player. This could help expedite things and offer cool perks.
  • Choose your video output resolution. Especially helpful for HD nuts.
  • Consider linking the player to your online account, if possible. Some players will use social media to share what you watch with your friends, as well as offering suggestions based on what your friends are watching.
