Common Problems the Project Might Face after the Installation of a New Lamp

The thing about electronic devices is that they tend to dysfunction if associated equipment does not function well or if a new device is installed. This is primarily because one device functions wells when all the associated devices function well – in perfect synchronization.

A similar case occurs with projectors where the change of a lamp can cause the project to stop working / partially working. Here are some common problems that a user may face as well as the solutions to each of these problems.

Read carefully to understand and notice if your projectors shows similar problems –

Problem 1. My projector doesn’t turn on after the installation of a new lamp.

Solution – The solution to the most common problem of the projector not turning on after the installation of the new lamp is rather very simple – check the power cord, lamp over and the lamp connections.

Of course, you can contact the customer service too if the problem persists, but before that be sure that the cord and the lamp connections are all perfect. In case of the lamp cove – if the cover is loose the projector certainly wouldn’t turn on. If the problem does not solve you can also open up the lamp cover and then check the connections.

Additionally, if the screws are too loose or too tight the projector remains in a shut down state and wouldn’t turn on until this issue is fixed with precision.

Problem 2. My projector heats up really quick after replacing the lamp.

Solution – The air filters and the ventilation holes need to be cleaned well.

The main reason for the heating up of the projector is because the air filters and the ventilation holes are now clogged with dust or other debris. DLP projectors operate on high heat, but most of these have one of more fans associated with it to blow air around the components to cool them off.

Building up of dust usually prevents the proper air circulation and can cause the projector to become very hot and in some cases even causes it to explode. When anything like this happens, the temperature controls usually stop functioning; thus make sure the air filters are always clean after a new lamp is added. You can make use of a can of compressed air to clear out the ventilation holes and air filters.

Problem 3. The picture quality seems fine but the onscreen message suggests lap replacement even though it is brand new.

Solution – Reset the lamp timer.

Every projector has an associated lamp timer or lamp hour counter that is responsible to automatically track the lamp usage. This has been specifically designed to send warning messages on the screen as well as to trigger the lamp indicator when the projector lamp is approaching the end of its functionality duration. Most projectors turn off automatically at the end of lamp hours – irrespective of the lamp being new or old.

Therefore, the simple solution here is to always reset the lamp timer and replacing the lamp (if that may be required). While simply resetting the timer would work under most cases, you may also be required to change the lamp if it is not compatible with the projector.

Problem 4. The picture on the projector appears dimmer than earlier.

Solution – Try re-installing a new bulb or replace the generic lamp that was previously installed.

This is not a usual problem, but if at all that occurs this usually happens when only the bulb has been replaced and not the entire housing. You need to make sure the bulb has been installed appropriately (not too loose and not too tight). Also, you need to consider purchasing a bare bulb considering that this is an economical option.

Understand the process of installation pretty well and if you are unaware about the same you can read the instructions and follow the mentioned steps. Remember, it should flush completely with the front of the lamp housing cage and the new bulb should perfectly sit in the same placement as the old bulb was.

In case the bulb is off center or not well aligned the image on the projector will appear simmer than ever before. Also, removing the bulb and re-installing it carefully than ever should take the care of the dim picture problem.

Problem 5. The screen colors don’t look fine and the picture is flickering.

Solution – The color wheel is asking for replacement.

Usually the color is off with the older and dimmer lamp. However, since the projector lamp only has one color which is white – the problem may usually be because of the internal optics. The color wheel or the other optical components may have been damaged during the replacement of the lamp.

Additionally, installation of the generic lamps may cause damage to the sophisticated and sensitive components such as the color wheel or the DLP chip. The only solution that is available to a problem like this is to contact the service center.

Problem 6. Projector turns on for some time and then automatically shuts off!

Solution- The fans and the filters require cleaning. Other solution could be to replace the generic lamp.

The thing about projectors is that they automatically shut off if they detect any problems. Cleaning the projector of any dust and dirt will make all the components work in complete harmony. If there is no dust, then the problem could be in the actual lamp.

The generic compatible lamps don not operate perfectly in most projectors causing imbalance. This will make the projector shut down automatically. A right end solution is to replace the generic lamp with a genuine OEM lamp.

Understand the common problems and the possible solutions for each of them to improve the performance of the projector.
