Light flickering then only green stays on. Chip problem ?
Optoma EP-739. After couple minutes get light flickering then only the green stays on. I was told it could be a chip going bad. Are these chips easy to replace ? not integrated to system board ? or would I be better off replacing entire motherboard ?

Check poewer connection Check if fan filder is dirty ( if it is just hoover it out) If "lamp" light on top of the projector blinks or stays lit - lamp probably faulty How old is the Projector/lamp (average lamp life is around 2000-3000 hours)
It sounds like the projector itself has a fault. Sadly it's often uneconomic to repair budget projectors which are out of warranty when the cost of repair is compared to that of replacement. You should speak to Optoma support and see who their local agent is, and then ask for a quote.
1 - Hold the clear tv buttom until all 4 light flash red 2- Press the red tv buttom 3- Press the amount of time needed on the up cursor ( around select buttom) until your tv shut down 4-When the tv goes off press the search buttom ( at the end on the right side ) 5-Press record
Then u can use the red tv buttom to control ur tv and u can control the volume on satelitte mode without going back to tv mode , if u press too much time while searching the code and the tv wont light back , do the same thing but instead pressing the up cursor press the down one to go back on the code it will be faster .
