My power button does not stay on (the green lamp)when turned on from the remote or the unit. I checked the fuses on the main circut board and the have contineuity. help model vs-50609 mitsubishi rear projection. I fell asleep one night watching a dvd and the tv was left on most of the night. 6 hours

the clicking sound is due to the relay is getting turn on but doesn't stay because of bad component in the power supply board or in the main board. you must check first the bridge type diode and FET transistor using an analog or digital tester.

Hello; This problem is likely caused by bad inverter board(s). I think there are 2 on the left side on this model. If either inverter doesn't start, the microcomputer on the main board see's this and generates one "lamp error" . Once it counts 5 lamp errors, the screen will not light and led(s) will flash. These boards are about $100 each and no way to know which is bad. It can also be caused by a bad LCD panel ( cost more than the TV sold for). You can verify a lamp error problem by doing a "forced start" . The set must be unplugged. then"I think" Hold the channel up and volume down buttons on the set or VISa Versa, and plug in without releasing these buttons for several seconds. If the set makes a buzzing noise , the power supply board is bad. If the set comes on and stays or goes off this is the inverter and/ or LCD panel problem. John

Tries unplug,replug the tv an hour later might work.But this a temp.fix,must replaced the backlight video board sooner or later.

Check ac to the set. Plug a lamp into the same outlet to test it. If ok then check fuse on power board. If fuse ok replace the power board.

When E5 service call condition occur for safety reasons they cannot be cleared by turn OFF/ON the power switch.After repairing the copier turn ON the main switch.Enter in the SP mode and press 97.Turn the main switch OFF wait 10 sec and turn ON.

the lamp ballast is bad and needs replacement.

Have you checked the filters? I have a Sanyo PLV-75 and had a similar problem.  The normal fan would come on when the unit was first started, then after a few seconds the secondary fan came on and then the unit would shut down.  Called tech support and they asked if I had cleaned the filters. I did it, and it worked great.  Check the manual for where the filters are and hit them first before getting a new bulb.  Hope it helps!

With the machine on, press clear modes(yellow button), 107, and then hold down clear/stop (red button). Enter 5810 then # key then 1 #. Turn off the main power then power back on. This code is a fuser lamp on condition. It should clear. If not reseat the fuser unit (gets hot), clear using above procedure and try again.

thanks for the info. care to try again?

Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.
