I have a Sharp LC-46E77UN TV. Remote will start TV green light on. No picture, just stays black. PVR is on and connected to TV via HDMI cable. Cannot turn off green light. Must use power button on TV and hold it down for several seconds before the green light turns off. Volume bar and Inputs do show up on screen. After a while both on green light and OPC green light start blinking.

This happens all the time.

My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.

• Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.

Problem is caused by television broadcast

1. Push 'INFO' button.
2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.

Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.

1. Push NEXT SOURCE button on the remote.
2. On the screen appears all sorces.
3. Press the UP button to switch to the TV mode.

If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer

• Make sure the cable is well connected .
• To check which connection is selected, Press the i+ button on the remote control.

1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
   • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
   • The blank screen is caused by the accessory device and not by the TV.
   • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
   1. Press AV on the remote
   2. Press up and then ok
   3. Press AV again
   4. Press down and ok
   5. The compatibility check process between TV and accessory device will start over again.
4. Reset (switch off and back on) the TV and also reset the accessory device.

The X1 box acts like a set-top cable box. The HDMI output can be connected to any HDMI connector. There are three HDMI connections on the rear of the set. You have the Blu-Ray connected to one of them, Input 6. You should have no issues with connecting the X1 to either Input 7 or Input 8. There is no specific "TV" HDMI connection. You simply use the remote to select the HDMI port that the X1 is connected to.

You have to tell the TV which HDMI input to use. ie you should be able to press a button on your remote to do this. On my tv we can choose between 4 different HDMI inputs via the remote.

have you tried another hdmi source like a games system on the cable and tv hdmi socket to rule out a faulty now tv box
if other source still not sending picture try another cheap cable to rule out cable fault (borrow would be a good idea)try one of the other hdmi sockets on the tv to find the item that is the problem hdmi 1.4a is for 4k picture support as the cable needs a higher bandwidth to send the larger info stream

There should be some loose solder points at its main digital board. Check it.

if it was a new tv you can ask the supplier for check up it was covered with warranty.

I don't have a solution but starting 2 weeks ago I have the exact same problem. Test different devices and cables and it points back to the TV. Anybody have a solution?

It sounds like the Bluray player may be outputting the signal at a higher resolution than the TV supports. If the Bluray player has a scart or composite connection, connect with those first, and adjust its settings to output a lower resolution. Then reconnect the HDMI. Hope this works for you.

I got the sound on my LC32D6U fixed for free. Even though the TV is out of warranty, Sharp considers it under warranty for the sound problem. The number i 800-237-4277.
