Mitsubishi WD-57732 LAMP continuously burns out.
There are a few issues here:
The lamp you are purchasing could not be OEM, or a compatible lamp--OR you have a ballast/power supply issue blowing the lamp out.
The original lamp is manufactured by Osram, but a better and compatible lamp would be Philips, who pioneered the lighting for DLPs. The ballast needs to be compatible with the lamp and Mitsubishi ballasts are compatible with most lamps, but work best with Philips and Osram. Only buy from an authorized dealer!
Power supply was cut
you can buy a new power cord or you can use another wire to replace the cord. just buy the same size then you will need to remove the rear cover to access the internal. and then the old cord must be removed from the ac terminal pin and the assembled wire with plug that you buy can be replaced. you can directly re soldered the end of the ac wire at the pcb for ac supply.
