Lamp problem


IF NOT A TOSHIBA REPLACEMENT BUT A GENERIC LAMP THAT COULD BE THIS SET'S PROBLEM.

Other than that the Ballast that fires the Lamp may be the problem.

Note: if lamp only lasts several months there is another possible reason: Some of these sets had a setting in the customer menu for something like "quick on"===if your set has this and it is engaged the lamp never completely shuts off--this feature was so you did not have to wait when dead cold and off for twenty some seconds after turn on for the picture to appear.

Problem with this is when you turn set off lamp dims but does not go out and fan may shut off quickly that should cool the lamp when set is turned off.

Other than looking in the menu with a working lamp watch where lamp is when you turn the set off---it should go out almost instantly and the fan for the lamp should run about 3-5 minutes and then it should turn off.

It was a nice but stupid feature that a lamp running all the time affects your electric bill and really shortens the life of the lamp, most of us with remote start on our car will not leave it running 7-24.

Toshiba 62hm15a blows lamp after 3months


One possible reason I can think of here is I think this model had a quick start or quick on feature.

What will happen if it does is set will come on and work normally--when you turn it off and watch the lamp, it will dim down but NOT GO OUT--AFTER 3-5 MINUTES THE FAN WILL (LAMP FAN) go off.

It was a stupid feature, lamp is running 7/24 at about 40 percent brightness--idea was you did not have to wait the 10-15 seconds for brightness to come up and be normal when set is first turned on.

If this is your problem look in the main menu for a setting like that and disable or deselect it.

Set when cold will take longer to reach full brightness and when turned off lamp will go completely OFF and lamp fan will continue to run for a few minutes.

I hope this is your problem---PS if the set is real dusty inside it can cause issues but that is rare in this set.

Toshiba xp2 projector overheating


Better late than never for any other XP2 owners out there. I've gone through 1 lamp so far with very good results. The key to overheating is cleaning the fan out, i.e. it sucks in a lot of dust particles over time which accumulate on the fan blade and in the vents blocking good airflow. Take a good strong vacuum hose to every vent, then again right when you turn it on. This will get the fan up to speed quickly and assist with removing more dust internally. Eventually, you'll need to open the projector up and clean internally (carefully), but doing the above maintenance will prolong its life and extend the lamp too!

New bulb worked for a short trail run now wont light up. flashing green led colour wheel is turning on start up


when you changed the lamp, did you blow the dust out of the projector? if the screen on the side of the lamp is blocked (i.e. with dust), the lamp will blow quickly. if the projector were to overheat, by the fans not running or blocked vents, everything would shut down and the led would blink red.

Sony Wega KDF-55E2000 won't turn on


A 5 blink code is a lamp power supply problem, but I would try a new lamp. I'd say about 90% of the time that fixes the problem.Get an ORIGINAL Sony lamp as the aftermarket replacements are ****. If you replace the lamp and still have the problem, you will need to have the lamp power supply/lamp ballast replaced

A couple of things...

If the fan is not working, the lamp will not fire. If you have the owner's manual, it should indicate what the flashing lights mean. Check to make sure that the panels are seated properly. When you replaced the lamp, the outer cover was removed. If that is not seated back 100%, the unit will not work. There are a number of safety "checks" built into the unit to prevent damage and possibly fire as the lamps get really hot.

Check the items above and let us know your progress.

Overheating problem


With all respect for the repairman, he must have been a bit confused.
The only lamp inside a laptop is the one behind the display, and when it overheats, the laptop does not shut down. The lamp blows and laptop keep working with no picture or dim picture on screen, that is all.
Most common cause for overheating on a laptop is the fan on top of CPU, if it is not working properly or not well adhering to cpu surface, then the laptop will turn off after a while.
When fan is ok,a faulty motherboard or faulty CPU can cause the computer to shut down, no lamp at all in all this, the repairman must have confused your laptop with a laser printer.
Here is a tool to check computer temperature and fan speed, click where it says SpeedFan 4.33. under download.
...if you cannot fix it by yourself I suggest changing repairman...
