Hi , I`m Jack
Perhaps I can help you with this problem , a few questions coming up and please note that it may take a few minutes between replies;

Did you replace the lamp because the old one completely failed or is it still functional ?

What happens if you re-install the old lamp ?

Did the tv start this cycling exactly at the moment you changed items in the service menu ?

What I need to know here is exactly when did that cycling started

Customer: replied 1 year ago.
It did it when I changed something in the service menu right then it shut off and came back on over and over

I unplugged it still does it

the other lamp did completely fail so replaced it with new one which I got on the service menu to reset the lamp timer and selected some other lamp thing thing that said pulse

O.k then , reason for asking is that this sounded like a very common problem for this model , namely a defective ballast that would cause this exact symptom and this would also match install a new lamp out of specs that killed the ballast, i.e a $30 knockoff lamp from amazon or ebay.

That would`ve been the easy solution but now obviously your main board has gone the deep end because of mishandling and not much can be done but replace it in this case

I`m sure you do not like me being that blunt but there is no other way to say this , there is no need to reset the timer on those tv`s , it is just a tool for serviceman`s and will not stop the tv from working .
