Hi i jave a mitsubishi L75-A91 and my hdmi ports have stopped working how can i fix this


Try a factory reset. If it do not help you, check and replace its main digital board.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Replaced lamp on mitsubishi wd62527 worked for 10 minutes then shut down. Now red lamp light is on


If the red indicator light on the front of your HDTV is glowing a solid red, you should first unplug the AC cord from the wall power outlet and wait for 60 seconds before reapplying power to the HDTV.

After you turn the TV on, if it doesn't power up, try holding the power button down for at least 8 seconds. That's supposed to force a system reset. If your model has a system reset button, use that instead. Press the reset button for about 20 seconds...release it and press it again for 20 seconds, release it again and the led will blink just for a minute or two. You should now be able to turn the TV on.
If after several attempts, the HDTV has not fully powered on and the LED on the front of the HDTV is still glowing solid red, you may want to reseat the lamp.

If reseating the lamp has not resolved the issue then your next step is to order a replacement lamp.

PD523 no picture, led blinks


Hy !

Seems to be the colorwheel. When a segment is broken, the unbalanced wheel causes vibrations. Costs approx. 100-150$. Take away back and top so you can see if wheel is not complete.

Good Luck!

Progressive power up problem


Yeppers. Sounds like the standby power supply has a bad capacitor in it and the regulator Ic is defective. These parts should only be replaced by quilified technician as there is very high voltage inside these sets. Good Luck
