Our 6 year old Sony TV recently started randomly turning its setup menu on and off and cycling through random options. The remote doesnt seem to be working at all (cant change channels, volume, etc..) and I am unable to change any settings on the TV itself. The on/off switch and the volume button is working but I have little success navigating the setup menu. I have tried "resetting" it as Sony has suggested, no help. Problem is random, will go for weeks without issues (we do have to hit the volume minus buttom when turning on the TV to get rid of the setup menu, takes care of the problem) but when the problem flares up nothing seems to help. Also we didnt notice this proble till a few weeks after our 2 year old launched his matchbox jet into the TV (near the button controls) Any help would be greatly apppreciated.
One of the front control switches, that are located in the back of the buttons on the front of the set most likly are damaged or broken. These switchs are small and your going to need to pull out the entire chassis of the TV set to replair or replace them. If you have solid state TV repair experience thenm it should not be a big deal, but if you DONT please seek out a local tech to assist you with this repair as sliding out a TV printed circuit board can be a tricky thing, as it can bend ,crack or pop the surface mounted componets right off the board. A repair like this shouldnt cost alot. really all depends on if the board is damaged or not. good Luck
