Cleaning the Sanyo PLV-60 LCD Projector

When I first picked up my PLV-60 it was in excellent shape and very clean but it did have a couple of dust blobs on the LCD panels which showed up on the screen as fuzzy green spots. I decided to give it a good cleaning before I hung it up on the ceiling and here is how I did it.

If you decide to follow anything that is written on these pages please do so at your own risk. I assume no responsibility for any damage you may cause your machine, this information is provided purely as reference.

There are three fans on the bottom of the projector (when the projector is setup for table top display), there is an additional fan at the back of the unit and then there are the three LCD panels inside of the unit. I will discuss how to clean each here.

Lets start with something easy, the three fans on the bottom of the unit. Lay down something soft on the ground, I used a towel and place your projector upside down on top of it.

Under the center panel are three fans, just use your finger and hit the three tabs and pull the panel back.

My fans weren’t too dirty but while I still had the projector on the ground I took the time to clean them. To remove the fan covers just use the black tabs and turn the grill till they pop off. I then took the grills outside and used some compressed air to clean them out.

Now we need to take the projector apart a bit to get inside to the guts. Don’t worry, if you are careful you won’t hurt anything, just take your time.

There are a series of screws that you need to remove in order to get inside the projector. There are two on each side of the projector, two on the bottom, two on the top and one on the back. The two on the top and the one on the bottom may not need to be removed, these will remove the shroud around the lens and I am not sure if it’s completely neccessary to remove them or not. It doesn’t hurt to remove them though. The following pictures will show you the locations of the screws that need to be removed in order to get inside.

Ok, with that done you are ready to start disassembly. I removed the lens shroud next, I am not sure if this step was necessary or not.

Next, you want to open the projector up. But beware, there is a wire that is connecting the top panel to the rest of the projector. Open up the projector like a door, making the part closest to the lens the hinge.

Now, I disconnected the top panel from the bottom. This step is probably not completely necessary but I found it easier to work with this way. There are two connectors that you need to unplug, just make sure you plug them back in as the way you took them out. After these are unplugged you can remove the top half from the bottom. I didn’t take a picture of it but at the back of this top piece is the grill for the back fan, go ahead and give this a nice cleaning while you are in there. Here are the connectors.

Now you should be able to see the LCD panels. At this point I tilted the projector up so that it was sitting on its side. I did this because you want to make sure that you keep your compressed air bottle vertical. Shaking the compressed air can or tilting the bottle can cause some of the stuff in the bottle to come squirting out and it can get on the LCD panels which could damage them. You want to blow a liberal amount of air in there to make sure you get all the dust out, just be careful.

Once that is done your projector should be all cleaned up. Just put your projector back together using the opposite steps that you used to put it together and you should be good to go. Hopefully your projector is nice and clean now and any dust blobs you had are gone.

    Hi, I hope you can help me with a problem I have. I tried to find anything through the web but have not been lucky so far. Then I found your site and maybe you have a tipp for me. I have the Sanyo PLV 60 Projector and it is running quite good. The only problem is, that the backside fan is already old and very loud (the fan above the power switch). Therefore I wanted to put in a new one. And that is my problem. I do not know how to get out the fan. The problem is, that the bottom projector case is blocking the screws to dismantle the fan. I tried to dismantle the botton case but could not find out how. Hoepfully you have an idea and would be so nice to share this information with me. thank you an I wish you a nice day.

    Andy, I’m sorry but I have no idea how to remove that fan and I no longer have the projector to look into it.

    Good luck.
