You may need to replace your Tvs convergence board. Go to www.partstore.com and type in your Tv model #. It is a simple swap procedure with no soldering. It costs about $80 or more. It takes 30 to 45 minutes to replace.

Shuts off and on while trying to watch, the power light flashes 30 times when off then the tv comes back on again


Power supply trouble. The TV keeps trying to start then operates for 2 seconds and shuts down. The cycle keeps repeating until eventually the TV will not start at all.

Replaced bulb but tv comes only comes on for about 10 to 15 seconds then shuts down and red light flashes


It sounds like you have a bad ballast board, or possibly the power supply going to the ballast bulb. I'm afraid that if you do not have the repair experience on solid state TV sets, you will need to contact and authorized Mitsubishi repair center. Good Luck

Lamp light blinks 3 times shuts down


The CLS problem. Im thinking that at least you made a visual inspection of the power suply and the capacitors around it. Then if everything normal in the area then the microdisplay (inside the ligth engine) can be damaged. (when the tv is working normally the microdisplay sends a pulse to turn on ballast and lamp finally.

The sweetkyman: when the fan is bad th tv shuts down imm. (if you unplug the fan when the tv is working normal the computer detects the overcurrent system works and shuts down the set) when a fan is all dirty and tons of dust on it the tv tends to work but after some hours the tv shuts down.

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off

TV not staying on


If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!
