Recently replaced main board which fixed the problem of not turning on. Here is the history: DLP chip was replaced by previous owner in 2012 to fix white dot issue. I replaced the capacitors on LED PSB in 2013. Replaced red phlat in 2014. Replaced main PSB in 2015. Replaced power cord with noise filter from newer TV model which is a little different and main board a few weeks ago. TV has been turning on better than it ever has but a couple times had to unplug it to get it to come on when it did not go back to standby mode after going thru start up process. I can live with this as it seems to have gotten better. The problem I'm having is it loses picture settings within hour or two of setting them. Dynamic, Standard, and movie all go back to factory just like u would press reset. Funny thing is at first I thought it was losing them when powered off but that's not the case. Only thing I notice different is the light around the power button on TV is not working. Melody still works though. Only settings I can see its losing is the picture settings. Anyone know what this could be?

About every hour or so screen goes blank for just sec and that's when it loses picture settings. Sucks cause its a little dark on factory settings so like to increase brightness . I'm going to see if it does it leaving settings at factory settingsComment

As long as TV stays on factory settings it does not blink and all is good. If I change pictures settings at all , increase brightness, it will blink for a second to black screen then come back on with factory settings just like pressing reset button. It does this exactly 30 minutes from time of changing settings every time. If I have menu screen pulled up 30 minutes from time it won't but will 30 minutes from then. Its like this new main board is programmed to do this. I mean its exactly 30 minutes! If left alone all is good but during the day I like to have it more bright. I have never put in the service code to see if something can be done. Anyone?Comment

Hello,
It sounds like your main board is in store or retail mode. Go into the service menu ( mute, 1,8,2) then perform a factory defaults. This will allow the initial settings to come up just as if the tv was new out of the box. Make sure you select home when setting the tv up. Hope this helps.Comment

Will know in 30 minutes. I hope so cause tV coming on first try faster than ever has since given to me in July 2013. I now have $235 invested. Took me 3 months to find this board though. Paid $124.Comment
