Re: Sony KP-57WS510 57 in. Rear Projection HDTV
if the rolling is slow that mean you have a fault in the vertical and sync seperate part of the tv and need a technical support to slove but if it is fast yo can set it up with the vertical hold knub in the back or you have to open the back cover carefully that if you know how to do that but be carefull tv is a dangerous set hazard ,
look for the vertical hols variable resistor and fix it to stup rollinf
for the sound fault , if you hit the side of the tv does it comes normal ?/ if yes then some part need to be resolders dried up soldering pin

Make sure you try two different sources to the tv, such as a cable box, dvd player and/or gaming system. If you have issues with all sources then it is for sure the tv and there should be a format option. However if it is only one source that the issue is with the issue is of course the source.
When a Sony TV flashes five times, that means that there is an AKB circuit fault.
This means that there is something wrong with the video.
When you get this error, several IC and components concerning the video signal must be tested and eventually
That is not a vertical roll from side to side, this is a horizontal rolling. if the vertical had a roll it would be going from top to bottom. This is most likely a coupling between the horizontal sync circuit and the sync separator circuit. Good Luck
