Magnavox MS3252S431 The screen on my 15 month old Magnavox model MS3252S431 (chassis L01-1UAC-7638) 32-inch TV goes blank with a clicking sound. The green power light stays on. If I power off the TV and then power on again everything is fine.... sometimes for a few hours, sometimes the problem occurs again in a minute.I change the R3340 but still same problem plus first the volume bar will appear and sometimes lower the volume by itself. then the main tv menu will appear on its own and randomly move thru the menu. the 3rd stage is it will do all of this.
