Re: screen removal from vs45va2

If you want to clean the projection lenses, you do not want to remove the cover screen to get there. That is the hard way, but you should be an experienced technician to do this correctly. Why do you think that the lenses need to be cleaned? What are you seeing on the screen to make you think that the lens needs cleaning?

Just wanting to know how to remove the front screen to clean the dust of the projectors

You can do that but an easier way is to remove rear cover (set unplugged)and clean the lens with a lens cloth or paper towel with glass cleaner sprayed on it.

It is fairly easy to damage screen when removing it/replacing it.

Let me know what you find.

How can I remove the back cover on a SAMSUNG HCR5245W, I need access to clean the mirror and projectors. Already removed all screws. The back cover appears to be made of two parts but I cannot split. From...

Hi my name is Roety,
I can help you with your issue ,
Leave the top rear half bolted on.
Remove the rear edge screws to remove the front half, then remove the front lower section by taking out the few rear screws holding it, then there is another piece just below the screen that pulls off revealing the last few screws holding the top front screen section in the front lower edge.  Take the front off, cleaning the mirror and lens will help, but I'll bet the fluid is dirty inside the blue and green tubes, look into the tubes with the TV on to check.
best of luck

How to take cover off

First, my disclaimer:

I have a much older projector, but the way they are constructed hasn't changed a lot to my knowledge.

An excess of dust can shorten the life of electronics, it's a given. But the majority of these sets are allowed to collect dust for many years of operation before any problem occurs.
I sense that you may instead be asking about cleaning the lenses and mirror. Actually, the mirror, since it faces somewhat at a downward angle in these sets tends to stay clean. the lenses however, face upwards, and do get quite dusty, causing a blurry picture, with ghostly images on the screen at their worst.
To clean the lenses on most RCA sets I've seen, the screen must be removed. Allow the set to cool and voltages to dissipate for 30 minutes before beginning this process. There should be a removable panel beneath the screen, usually retained by screws on the backside at each end. REmoving the panel will expose the screws that keep the screen in place at the bottom. With the screen removed, the lenses (there are three) will be quite obvious. I clean mine with typical glass cleaner and SOFT paper towels. PAY ATTENTION not to allow any liquid to drip into the projector below or you may disable the projector unit possibly causing damage that must be repaired. If you are successful at the lens cleaning you will have restored the picture quality to like new.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

Hitachi 53UDX 10B 53in Rear Projection

Steve, easier and safer to remove back panels, remove bottom back cover then remove top back cover, be advised the top cover has a giant mirror on the inside so it will be heavy and easy to break, use 2 people to remove it, this way you can get at the inside and clean the mirror at the same time, hope this helps and Happy New Year, BMW Rider

Need to disassemble Mitsubishi VS-6041 60 in Rear Projection

Wow, You are asking for a complete disasemmbly. If this is necessary, you have to remove any screws you can find that are connected to the front panel. Usually they are in the top of the set ( you'll find them after removing the mirror panel and mirror ). I wouldn't remove any tubes as the tube convergence would have to be all reset and that would require a cross hair generator. I do hope this has helped in some way, but all I can do is send you my best wishes as I certainaly don't suggest disassembly if there is any other way. Good luck
