Hello the lamp most likely is going bad once the set comes on the lamp light won't come on to tell you it's bad but the amount of times the light blinks in a row tells us whats going on. you need to clean with a vaccume the vent areas on the back cover to make sure the fans can cool it properly (never use canned air our blow any thing into the tv, it could blow dust onto the optics and cause a distortion in your picture-little splotches) just order a sony lamp and put back in the tv, some after market lamps can cause a lamp driver board failure and that will take a tech to fix.thanks.....techman
