Make sure your video and sound cable is working (rca, hdmi cable etc) and your source component like dvd player or settop box is working. If cable is plug into a socket AV 3 or HDMI 3 for e. g. make sure the tv is source or input is selected the same like AV 3 etc.
It is possible for the TV to switch on or off but no picture or sound. This means the input board or tv tuner is faulty in which case you need a good tv repair technician
The wide button on your remote adjusts the picture size. Each time you press it you adjust the picture. If repeatedly pressing the wide button is not changing the picture size check you cable/satellite remote control. Look for the hdzoom# button. There may also be an aspect or format button. When you adjust this the picture size changes and between the Sony remote and the cable/satellite remote you should be able to come to a happy medium. If the picture size still isn't changing you might not be set to the correct resolution i.e. 1080i on your cable/satellite box. It might be set too low or you might be in the wrong input (av 1 av 2 hdmi 1 hdmi 2) etc.
which AV connection are you using? HDMI or the cable supplied with the PS3, If using HDMI, you have to set the PS3 visual settings to HDMI, to do this, use the cable supplied with the PS3, and have the HDMI cable plugged in. Then while using the cables supplied with the PS3, switch the settings over to HDMI, then change the TV's input selector to your HDMI and confirm the settings changes. Hope it helps take care
I think the problem stems from the HDMI port and scart ports, i have read somewhere on a sound and vision web site that these two conflict and when HDMI is in it only sometimes blocks out the scart signal.
This could be what the problem of the freezing is, as when all said and done its just a very large pc monitor; and look at the trouble they can get in!.
