I have this set that will not go into ext.video mode.The customer is trying to use a new dvd player he bought but he cannot use it since the tv will not switch to ext. The remote has the input button and I tried that but when I push it,the screen just blinks and the tv goes back to ch 3.Will not say video with oo at the top corner.I also tried pushing 99 and 00 to change over but did not work.He said another shop did the tuner work about 1 yr ago.I checked the tuner grounds and all seem ok.No solder splashes. If someone has had this or is familiar with it and can help,I would apreciate it very much.
