I was given this model tv. The green and red lights on the front are flashing. Says to replace bulb and close lamp cover correctly. I am missing the lamp cover. Is that going to be a problem?

U mean the Lamp door cover?Yes?Tv might work,might not.Don't know never tries to turn the tv on before without a Lamp door cover close before.There is a blue safety switch though must be press down when the Lamp door cover is close.Test it out.Why don't u just take a piece of tape and tape that blue safety switch down tightly,than turn on the tv.If the tv message that said close lamp cover correctly disappear.Than yes the tv will work,without the lamp cover closed.Now u just needed to do a replacement of the tv projection lamp only that all.
