Can't open Filter

My projector says "Clean Filter" every time I start it. There are 2 small ones that I've tried to clean and I'm pretty sure there is another filter near the bulb. I can't open it. It opens about a 1/2 inch and won't go any further. How can I get to it?

Is a subaru outback 2002 2.5 engine, hard to start cold and running rough under acceleration stall when push accelerator pedal and sometin]mes die no power. codes P0171 and P0130


Check the following items:
1. good clean air filter?
2. no leaks in the air filter box, cover closed properly?
3. connecting hoses attached to the air box properly?
4. pcv valve working correctly?

1. Change the air filter if you don't recall the last time it was done. I record the mileage on filter with a permanent marker. Put it in a location where its visible with the air box opens. Change the air filter every 2 years or 30000 miles which ever occurs first.

2. Ensure that the two parts are aligned properly and that all the clamps and hoses all fit correctly. A good way to find vacuum leaks is to use vaseline on the ends of any poor fitting hoses. Do one at a time and you can isolate the problem hoses.

3.The two vent hoses that attach the valve covers to both sides of the air box can become loose with age. Adding some screw clamps can solve a small leak. Replace the hoses if they are hard and dried out. Also inspect the throttle body connection part of the air box for loose clamps and fitment.

4.Pcv test is pretty simple. Start the engine, open the oil cap, then hold a piece of paper over the cap. If the pcv is working the engine vacuum should try to suck the paper in. If the vacuum is weak then clean or replace the pcv valve.

If the all the above checks are good then its time to replace the front oxygen sensor.

Optoma hd65 has a red light. Only had it for 5 months. How do you fix?


The red indicator light usually comes on when something needs attention. Most often it has to do with the lamp timer or the filter timer. The projector keeps track of how long it's been since you've changed the bulb or cleaned the filter(s). You can reset these timers in the menu. Be sure to clean the filter before you reset the timer

This is my occuring problem I've been having: Bike starts up fine and will run fine in any gear if going slow and not opening the throttle lots. But as soon as open throttle lots the bike instantly...


this does is not related to the idle adjustment. It sounds strange that there is no fuel filter, there should be. the screen is for only stopping any large debri from going to the carbs. follow the fuel line from the tank valve and I will bet you will find a fuel filter. i also would suggest draining the fuel bowls on the carbs and catch the fuel. check for any debri in this gas. You may try running some seafoam carb cleaner thru the carbs. After changing filter and bowl draining does not work you may have to remove the carbs to clean them and make sure all is operating correctly ( slides). be sure that your air filter is also clean.

"clean and reset filter" alert is displayed even


You can reset the "Filter Time" on your projector and it will clear this error out of the system.

1) Clean Filter
2) Turn the power on
3) Hit the Menu button
4) Once the menu appears choose "Options"
5) Choose "Filter Time"
7) While the time is displayed hold the "Reset" button on the remote for 3 seconds
8) The "Reset" menu will pop-up and choose reset.

That should take care of it.

After tuning on PLT735U, we get proper display and then less than 10 seconds later, it shuts down.


Do any of the lights turn a different color or blink? Please let me know as this can tell me more specifically what is happening.
Many time projectors turning off like this can mean overheating.

  • Check the filter on the projector, this is usually behind a small plastic piece that is held in place by a small clip
  • Carefully wash the filter and let tap dry with a paper towel. Be sure to have it completely dry before replacing it.
  • Make sure all of the other opening on the projector are free of dust/dirt as this will restrict airflow as well

I little dust will do a lot of harm, keep it clean and you should be all good.

The full manual fo the unit can be located here:

I hope this helps,

When I turn on my hitachi CP-X205 projector, there is a very noticeable "fan" sound. Yesterday while using the projector it made a sound and then turned it self off. After unplugging it, I plugged it back...


Hi!

You need to clean the projector. Take of the filter and clean it, open the topschell of your projector and clean it.
In time a projector collects a lot of dust inside, if you dosenrt regulary clean the filter the dust pass it and stucks inside the projecotor. Use compressed air for the job but be verry verry carefull so you dont damage anything vital. If you arent sure how to to it i sugest you take it to a electronic repairshop, its cheap and they will clean it properly.

Good luck to you

My projector turns on then off


Probably your projector filter is full of dust, and probably even the inside id full of dust. You need to clean the filter and you need to clean the inside. The fan starts coz the lemp inside cant get any air, as soon as you turn the projector on it gets overheated.
Go to a pro and let him/her clean your projector good, then it should work properly again. And make sure that you clean the filter at least 3-4 times per year.

Good luck

Displayed massege to check air flow


With most projectors there is a foam air filter behind a grill that is the opening to the cooling channels. A fan ensures air flow to cool the lamp, etc. This filter prevents dust from gumming up the works (and depending on design) may prevent dust getting into the optics. As the filter gets dirty it gradually cuts off the air and at some point a protective circuit kicks in and turns off the lamp.
If the projector is on you will feel a stream of hot air coming out of the exit vent. Projectors vary in terms of amount of air flow, so its difficult to define what is normal for a specific model. However, you can simply hold a hand in front of the vent and see if there is air flow (It will be hot air so, careful). If there is a "good" stream of air things are fine, but if only a very light flow is felt the filter may be dirty.
If the filter has not been cleaned or replaced recently make sure the projector is turned off and cooled down then take off the inlet cover and remove the filter. Clean or replace per the instructions for the projector (and periodically as defined .. but taking into account the operating conditions). Once cleaned turn on the projector and feel the "normal" air current for future reference.
Heat is one of the major causes of projector failure, so make sure cooling vents (inlet and outlet) are not obstructed and filters are kept clean
