I've had my HLR4267W for several years, have replaced the color wheel before and the lamp. Now, recently, the screen seems to go from normal brightness to slightly darker and back to normal darkness every few minutes. I have not timed the interval between but I have a feeling it is becoming a little more frequent.
Is this my light bulb going bad again or something else? Last time, I remember the screen was getting darker over time, but nothing like this. I just want to have an idea what could be wrong. If it is anything more than a light bulb, it may be time for a new TV.
