My Dell 42 inch plasma tv has an issue with the picture blinking on and off when using the HDMI input. All of the analog inputs work fine.

Hi Caleb,
To resolve this, please perform the following steps:

• Turn off the TV and unplug the power cord
• Connect the HDMI cable to the HDMI port of your laptop.
• Connect the other end of the HDMI cable to the HDMI input on your HDTV
• Connect your device using the HDMI connector (Refer to image below)

• Plug in the power cords for the TV and Xbox
• Turn on your TV and Xbox
• Enter the TV Menu and select Setup (Refer to the image and steps mentioned below)

• To enter the TV Menu, press the Menu button on Remote control
• Use the left and right buttons (volume buttons) to move between the icons

Select correct input source

• Input allows you to select the proper source based on how you have your TV and video equipment connected.
• Press Input on the remote to go directly to the Input Select menu
• Select HDMI 1 or HDMI 2 (Refer to image below)

If the TV does not work, please follow these steps:

Verify the PIP/POP/PBP function is disabled ( PIP/POP/PBP Compatibility - The only input sources that cannot work together are HDMI with HDMI)

• Press the Menu button on the remote control or TV
• Use the Left and Right arrow buttons (Vol +/-) to select PIP/POP/PBP, and then press <Enter>
• Use the Up and Down arrow buttons (Ch Up/Ch Down) to select PIP/POP/PBP/OFF
• Use the Left and Right arrow buttons to select Off

If issue is still persists, please move to the next step

Reset the TV current input to its default configuration

• Press the Menu button on the remote control or TV
• Use the left and right arrow buttons to select Setup, and then press Enter/OK
• Use the Up and Down arrow buttons to select Factory Reset, and then press Enter/OK
• Select Current Input Setting and press Enter/OK
• Re-check the TV functionality

Plug the HDMI into laptop and T.V first then turn the laptop on, I have the same problem sometimes just doesnt read it properly if the laptop is already turned on when plugging in to HDMI. Hope this helps

Does it show a Menu at least? If it does then just switch through the INPUT until you see a picture. Cables most likely to be Video 1, 2 or 3. Video games "LINE", or HDMI..of course "HDMI".

Your remote should have an "INPUT" button.

You may have used Monster cables which can expand the plug in the TV.
Sorry, but you'll need to get a new input or use tape to hold it in.

Does the line appear on just one input(cable,hdmi,video1,video2,ect) or on all of them? The reason why I ask is it may be just an issue with one input setting on the television and you may be able to use a different input for a temporary fix of the problem. Plasma telivisions run very hot and it may be overheating. Try using a small mountable fan above the TV pointed into the back heat vents and see if keeping it cooler keeps the issue from happening. These TVs are repairable but usually cost more to repair than what it is worth due to plasma TVs are very in-expensive now.

howto get the hdmi signal thro hdmi to dvi cable in plasma pdp42 sansui tv in dvi input

the mainboard, controls the audio, Tv Tuners, Vga , HDMI, S- Video inputs.

The Y sus or (Y-Mainboard ) Is used to control the Panel (LCD) Video, it has 2 buffers that contol h/v lines in upper & lower regions.

Are you using the HDMI connection on both units, the SC-PT760 does have a HDMI input Yes/NO ? If not then it has HDMI output to the LG for HD Picture. What I would do if no HDMI INPUT to the SC-PT760 is available, run out of the TV with the Digital connection into the SC-PT760 Digital Audio in, assign the input as tv and you shoild get TV audio out of your home theatre, you could also use the analog connection audio out of the tv to the home theatre but this would not yield a dolby digital sound.

Have you try to replace your HDMI cable?I recommend you to pick up a good Monster HD700 HDMI cable from a local retail store like best buy or circuit city.In case it isn't the cable problem,you could return it.
However,when you are a using the HDMI cable,it is normally either have both picture and sound or nothing at all.Are you sure you didn't hook up the audio OUTPUT from your TV back to a receiver input?
Or even an optical output from the TV to the receiver?
