Lg 22ls4r hdtv screen flickers

Check the firmware on the tv. I would imagine youre connected with hdmi, and some tv's (lg, vizio mainly) have had firmware issues. check teh lg website for updates.

check if something loose conection.and reply.

hi. i have the same problem with my sky HD box and the same lg tv as you,

did you solve the no sound through HDMI.

You could have a Driver Board that has a loose connection or a Ribbon Cable that has a intermittent connection to the Plasma Panel, or a defective Plasma Panel. Either one could cause the problem and I would recommend only a Qualified Service Person to check it out.
Here is LG's Customer Service Number. 1800-243-0000. They could direct you to a Local Service Facility.
I hope this helps,

Make sure you have the PS3 set to the correct frequency for the TV. Many cannot accept 1080p / 24fps etc.

Try different settings.

I hope this helps.

Sounds like from discription the sky feed is set up for analog channel 6. With my TV-HVR-1600 card, there is an option in the wintv application when you click the menu button in the application that says channel suite. If you select this option, you should find and option for analog source. Select analog source in this screen and you should be able to manually add channel 6 in the box at the top of the analog souce screen. Also if you have the sky feed connected and you you click the scan button on this screen, it should detect automatically is the sky feed is on.

sounds like sky tv issue, try different cabling

there are 2 types of flicker, one is the lamps that drive the display and the second is the sync signal of the video.
I assume the video sync is the flicker you see,
I would try connecting a different way to make sure it is not the tv,
connect using the aux /rca connectors to cable box.
and or connect using the cable direct bypassing the cable box.
I have seen several complaints about the hdmi cable signal being incorrect in some way,
this is the same issue that the svideo connector had in its early adoption signal was too hot or too low.
another thing to watch out for is the low light sensor on the front of tv if it gets an incorrect reading it can flicker the back light though it should be slow in doing so.
some times the flicker you see is not flicker but ac running through the sides of the picture from an ungrounded cable source.
how does it perform if you play a dvd player , with and without the cable box connected.

if your tv is on warranty take it back to best buy for a replacement.good luck
