I recently purchased my Hitachi 43" RPTV and wanted to see if I could improve upon by current geometry set-up as it was a bit out for my taste. So being careful, I accessed the service menu and recorded all the parameters before beginning to experiment with the settings. Everything was fine until I started to tinker with the FREQUENCY field under the HORIZONTAL heading. My current setting was 06, but when I moved it a few notches lower the picture convergence got worse and then the picture cut-out on me before I had time to readjust and I was left with just the sound. The remote control then refused to work anymore and so I had no alternative but to turn the tv off and on, hoping to be able to put the setting back to what it was. HOWEVER, after I turned the tv off, it now refuses to turn itself back on and it goes through a series of 3 clicks where it tries to start up, but doesn't. I'm now in a bit of bother as I know that adjusting the service menu is not covered under warranty. So if I do call an engineer out and he manages to retrieve the picture, I'm worried that he will find the tv in service menu and realise that I have been messing with it and so then charge me. Is there any way I can get the tv going by resetting something or should I playing dum and call an engineer. Unfortunately, I cannot use the option of getting a replacement tv as this tv was discontinued a couple of months back and there are no more NEW ones around and I don't want to get an alternative as I tested all the others and this came out best in my opinion Can anyone help me, please?!!!
