Problem w60 inch using hdtv cable box

Set cable box to 1080i output only, the Philips 60PP will then work fine.

YOUR PROBLEM IS THIS. PHILLIPS MADE THIS TV WITH 5 INPUTS 1,2,3 ARE FOR REGULAR AIR,CABLE,OR DISH. INPUTS 4 AND 5 ARE ONLY FOR HIGH DEF TV CHANNELS . SO IF YOUR CABLEBOX HAS 100 CHANNELS AND 20 HD CHANNELS,IN INPUT 4 AND 5 THE 100 CHANNELS WILL LOOK SCRAMBLED AND IN INPUT 1,2,3 YOUR 20 HD CHANELS WILL LOOK SCRAMBLED. 99 PERCENT OF HDTV'S MADE IN THE LAST 5 YEARS DONT HAVE THIS PROBLEM BECAUSE THEY READ ALL SIGNALS IN AN INPUT. PHILLIPS MESSED UP BAD HERE AND SHOULD REFUND ANYONE WHO BOUGHT THESE.

I know this problem, happened to me with the comcast Motorola HD receiver box. The key is with the setting in the cable box. Switch on the TV. Set the channel to normal tuner channel 3 or HD input. Turn off the cable HD box. Press the Menu Button on the Cable box or the remote. You should see a Menu. Use the cursor keys to navigate The default setup is also one of the option, Right click on your cursor keys acts like the computer keyboard enter key and applies the change. The default setup is 16:9, the shacking would happen if you have set the picture type to "PAN SCAN". change it to either 16:9 or 4:3 Letter Box. The shacking should stop. Hope it helps.
