Recently, my 5000T picture freezes and then jumps to live again, and again, and again. Sound is unaffected.
The only solution is to turn off the power and wait a moment or two, then power up and all's well. It does this randomly when I turn it on first time. It's not the signal strength that's too strong, or too weak. It happens on SD and HD, and any channel, which suggests it's a video processing issue.
Any thoughts?
TIA
