Bad Bulb? I have the same tv (WD65732) and same issue. I just replaced my bulb 2 days ago. It didn't work right away but with reseating the lamp box it did work for about 2 days. It now will not give me video. It does not give me any yellow or red lights however. It does power up the fan, it then clicks rapidly (like an arcing sound coming from the lamp) for a couple of seconds and the fan powers down. It repeats this process 3 times and shuts off. If the louder fan sound is the balast, that seems to be working but the light doesn't turn on. I find it hard to believe my brand new bulb is bad already? Test your error code by holding menu and input button on the tv for 5 seconds. The lights will flash a certain amount of times (my case 6) then a pause and it will flash again (my case 6 again) thus giving 66. If it flashes 3 times pauses then 6 times it's a 36 error code. My error code is 66 (lamp unavailable) Here is the list of codes I found. I don't know if this applies to all Mitsubishi DLP tvs but here it is anyway: Press[ing] the front panel ?INPUT? and ?MENU? buttons at the same time,and holding for 5 seconds, activates the Error Code Mode. The LEDflashes denoting a two digit Error Code, or indicating no problem has occured since the last Initalization. Note: The front panel buttons must be used, NOT those on the Remote Control. ? The number of flashes indicates the value of the MSD (tens digit) of the Error Code. ? The flashing then pauses for approximately 1/2 second. ? The LED then flashes indicating the value of the LSD (ones digit) of the Error Code. ? The Error Code is repeated a total of 5 times. Example: If the Error Code is ?23?, the LED will flash two times, pause, and then flash three times. The following might be of interest: 12 No Error found 32 Lamp cover is open. Lamp turns Off while the TV is playing. 34(1) (Lamp failure) (Lamp Enable signal from engine is lost) 35 DM fan failed. (73'' only) 36 Lamp ballast fan failed. 37 Engine (DLP) fan failed. 38 Lamp temperature abnormally high. 39 DMD temperature abnormally high. 42 Lamp fan failed. 44 Check for disconnected DVI cable between PWB-DM and Engine. 46 DT connector (DMD Temperature sensor) disconnected. (73'' only) 47 Temperature of DM is too high. 48 Engine power supply short is detected. 57(2) Ballast communication problem (ballast to chassis) 58 Signal Short is detected 59 DM short is detected 61(3) No LAMP-EN output from the engine to the ballast Lamp did not turn on at P-ON sequence 66(4) (No Lamp inserted) (Disconnected cable between ballast and lamp) (Lamp-Enable goes to DM but not to Ballast)
