Re: oil low in red lamp
The substance is a clear antifreeze. The purpose is to keep the phosphors on the CRT cool so it wont burn. If the liquid was low, it means there is a seal or bladder leak somewhere. The tube needs to be removed and the leak can be patched with silicone rubber or the blader needs replacing.( check for cracks). Refill with coolant and re install. Use rubber gloves because the liquid coolant is hazardous to your health.

It means your lamp is burnt out and you have to replace the lamp with a new lamp. When you install the new lamp dont touch the glass lens part at the front of lamp or the oil from your finger will burn the new lamp and it wont work.
First, check if any of the vents are clogged with dust. If not,
try another lamp. They don't always look bad when they are bad.
If you feel handy, by the lamp itself without the cage and swap
in the new lamp. Make sure you do not touch the new lamp (finger
oil is bad for the lamp. The oil creates a hot spot and early failure).
Yes. It should show low ohms. If you've never used one before compare the readings to a norman light bulb and they should be similar. Keep in mind that oils from your fingers will shorten the lamps life if it is good. So if you need to replace it hold the lamp with a clean lint free cloth. Good Luck.
SEDI-POSSIBLY YOUR SET HAS A LOW 5 VOLT POWER SUPPLY.TEST VIA VOLTMETER ON PLUG J-9 WHICH IS ON LITE ENGINE .YOU WILL NEED TO REMOVE BACK OF SET TO MAKE THE TEST.IF 5 VOLT IS LOW BEST TO CALL A MITSUBUSHI TECH.JOE TV
red light blinks in 5 times then pause and then repeats. It is the lamp error. " Lamp Driver Defect"
When the "LAMP-PORT" (pin 95) is low, the lamp is not turned on. If the "LAMP-HV-DET"(pin 96) is low at the same time, it is classified as no high voltage of the lamp driver. I'm guessing it needs a Lamp driver which I think is on the C Board, which is part of the "Optics Unit Block Assy. The C Board cannot be orderd separately, and Optics Unit Blocks are not cheap. Good luck

(Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977020 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977020 5. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977020 6. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB (ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977020 .
