Have TV Questions? Ask a TV Technician
Hello, Try using the screws that were with the old lamp and see what happens.
Also, when it shuts down- are there any lit or blinking lights on the front of the set?
Please let me know when you are able to see my reply.
Okay, if the screws with the old lamp won't catch either, then it's likely the lamp is not inserted all of the way, or perhaps the lamp trigger switch was broken. Do you have the old lamp nearby and can you try to install that as a test to see if it will fully insert and the screws will tighten?
Well without the lamp screws being secure, you're likely not triggering the switch in the lamp chamber, and also the lamp door needs to be closed securely. Either of these will not allow the lamp to spark. Please install the old lamp just so we can see if you can get the red lamp light again. Reason being is that the lamp you purchased may be out of spec/or a knockoff lamp.
As far as the Lamps ShopJimmy carries- they are all over the map- they have copies and OEM both. So, I guess if the old lamp didn't really catch more than 1/4" either, then it's not likely the problem. So, let me ask you this- are you able to get the Lamp Cover to close securely? Also when you press power do the fans fire up? Can you then hear a soft click and buzz of the ballast trying to spark the lamp?
I understood everything you posted earlier. Also Phillips is not an OEM lamp for a Mitsubishi set- Osram (Sylvania) is. Anyhow let's move on from that part.
No, the lamp not catching is not the problem- the ballast will not even try to spark the lamp if the lamp was not installed. These symptoms point to either a bad lamp or a bad ballast in the TV (which is the lamp power supply).
When the lamp does not fire- what is the status of the lamp light on the front of the TV?
Okay none of this is lining up. I will need to opt out- which simply opens the question for other Experts to assist.
