Mitsubishi DPL TV model wd73c8, serial 100759. The tv will not turn on & has a solid red light in status.


Try to turn it on manually by the power switch - not by using the remote control. Try to unplug it for an hour or more to discharge the power system, then try again.

you must check the light indicator if how many times does it blink which tell the main problem or the error code of the tv. either the power supply doesn't work normally or the lamp need replacement.

The Power Light is Red


yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

I have a Magnavox 51" Projector TV. Model 51MP392H/17


Hello bullmuscle,

This is a power supply problem, I would suspect the HV power supply because the primary and secondary supplies anymore are tied to the HV power supply. This type of repair requires certain pieces of equipment, to test voltages, look at signals, and to if need be test for shorts in inductors (Switching PS transformer and Flyback transformer). I would not recommend that you try to fix this yourself, The cost for this type of problem is not that expensive and can be done in one evening, if the parts are available. You may be fortunate and it could be just a blown fuse, in the HV or LV power supply circuit

I hope this helps,

Thank you,

TV Magnavox 50ML8105D/17 Problem


I have the same problem my DLP TV would shut off after 30 minutes or less all red LED's. Solution: The fan on the lamp assembly was not turning at the proper RPM (bearing going bad) so it was going into overtemp mode. The original part number was a SUNON KDE1209ptv3 12v 1.3W I had a hard time finding one to match that spec. DIGI-KeyCorp (www.digikey.com) was able to cross reference it to a 3 lead P11034-ND part number (NMB-MAT model fba09a12L).

I Installed the fan and problem went away.
Procedure:
Remove the lamp from the lamp assembly
Remove the back panel.
From the back, slide the main circuit board to the left (loose one screw)
Remove the power interlock on the lamp assembly (2 screws)
Disconnect Lamp assembly cooling fan lead.
Remove the 4 silver slotted screws on the lamp assembly, 2 in the front and 2 in the back.
Carefully remove the lamp assembly from the rear. WATCH the Mirror.
Remove fan, cut leads and solder or **** splice on to the new fan.
Repeat steps for installation
