Have TV Questions? Ask a TV Technician
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Are there any lights you are seeing on the front (which ones, color, solid/flashing/pattern, etc)?Can you see the mitsubishi menu screens at all?Did you replace the dlp chip yourself, and did the tv ever work normally again after that was done?
Okay, it is possible there is a cord (wiring harness) that you didn't secure properly,
but the most likely issue is that you also have a bad dmd formatter board. That is a common failure, and often (about half the time) when replacing the chip you have to change out that board too, so that would be your ext step.
Yes, I'm here, I've been trying to locate parts for you. Unfortunately, that part is virtually impossible to find, no one has it in stock currently, and because this is an older model no more would be made either.
Can you look at the light a bit more carefully for me and see if there is any pattern to it?
There isn't always one, and that is okay, I was looking to see if there was as that can indicate a specific fault (diagnostic code).
You can open it up and recheck your connections, also check the lamp and that the chip is installed correctly.
But beyond that this would still point to a bad formatter board, which again cannot be readily found. You can watch for one on ebay (part BK.80L88.21G), but realistically it's probably time for a new tv at this point, this is a 2007 model that is well past its service life at this point, and the dlp technology is now obsolete. You can probably still return (or resell) the new chip, and you can get a brand new LED tv for around $800, with updated features and a fresh warranty.
Best regards, ***** ***** for the news,
Do you need more help with this?
