Turn tv on watch it for 20 mins. screen shuts off but green power light is still on. turn it off manualy wait a few mins. turn back on watch for anouther 20 mins or so then screen shuts off again


The reasion your set is shutting off is because the power supply is dieding, and you need to replace the electrolytic caps on the power supply, or purchase a new one, go to www.partstore.com sand check to see if they have your power supply.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
