Storage might have more than a little to do with the problem, especially if it has been subjected to freezing temperatures and/or high humidity, also some types of (used) capacitor do not take kindly to being "rested". Your tv seems to be a high value rather specialised type that would be best, after re-reading the instruction manual, entrusted to a repair shop; preferably a Mitsubishi approved repairer.

Might not be the bulb! IT could be the ballast or a temp sensor.

Possible color wheel issue

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size

Can you try this and post the result(s) here? - When the TV is OFF, Press & Hold the "Power" button for a bit more than 30 seconds. Please post the result here...Thnx

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty. Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs.

Try plug and unplug headphones, see if sound comes back, could try a reset of tv.

The was a previous answer on Fixya ( John Betancourt Apr 25, 2019 What I did I open it up and removed the panel and clean out the fan.it was very dusty.) I'm not sure that it will fix you problem but if it does let me know. There's a video on youtube which will a bit more helpful. It's called "Mitsubishi DLP TV Repair - TV is Blinking - How to Identify Blink Codes & Fix DLP TVs". https://www.youtube.com/watch?v=INird71KKtA

remove the lamp and check to see if its ok, if ok replace lamp thermal sensor

My guess is that it is not economical to fix as it needs new screen. Unless it's under warranty but then you would not be asking. I had an off brand tv that I sold at my Radioshack franchise year ago. I had a customer get a tv with one white pixel constantly on. I replaced it for him. When I called the mfg, they informed me that this was allowable error in the b grade displays they used in their TVs. I quit selling them and put the bad one in my Rv. Still ticked me off when I watched it

Model number given indicates it should be a 2000 year model.

If so, it should have the self check feature; try to turn the set on and when the green light goes off: On the front of the set press and hold both the menu and input buttons for at least five seconds and then release both buttons.

Power light will blink a two digit error code like: 2 blinks,pause and 2 blinks (2,2 error code is most common one). It will repeat the error code several times.

Let me know what error code you find and I will tell you what it may mean.

if this told you something you did not know rate this solution as "very helpful" as I do this here for free.
