I've had this TV for about 3 years and it's been going great. I've been anticipating a bulb replacement for quite some time and recently saw via the service menu that the TV has had about 10,000 hours on it. Today I went to turn on the TV and nothing happened, no picture. So I unplugged it, let it sit for awhile, plugged it back in and turned it on. Still nothing. Shortly after I notice the status light on the front of the TV is a constant (not blinking) red. Anyone know what this could indicate? Upon checking the Mitsubishi troubleshooting website it says:
If you receive a Solid Red LED indicator on the front of your HDTV you should first unplug the AC Cord from the wall power outlet and wait for 60 seconds before reapplying power to the HDTV.
If after several attempts the HDTV has not fully powered on and the LED on the front of the HDTV is still Solid Red you may want to reseat the lamp.
If reseating the lamp has not resolved the issue then contact Mitsubishi Consumer Relations to order a replacement lamp.
I was under the impression that if the bulb went out, there would simply be a dim picture, but not total blackness. There is definitely nothing showing up on the screen. Any ideas?
A couple side questions:
When replacing the bulb, does the bulb hour counter automatically reset, or do you have to do this manually? If so, how?
Could a dimming bulb cause lower quality picture? I feel lately that the picture just hasn't been quite as sharp and black levels not as deep
. I know with RPTV's, certain things can become misaligned or dirty that can affect the focus or sharpness of the picture. Maybe I'll open it up and have a look. But for future reference, plasmas and LED TVs don't have any sort of internal components which require maintenance such as cleaning or aligning to maintain pristine/optimal picture quality, do they? (Thinking I'm probably gonna get a plasma if this issue can't be repaired in a less-than-costly manner)
Sorry for the messy organization.
Thanks for any help.
