Default Cleaning your dlp

Hey guys, i know this has probably been discussed but how do you guys clean your screen?

I have a Toshiba52hm84, and currently I use a soft T-shirt, and if there is a fingerprint, i add a very tiny amount of water and gently wipe it away.

Is it worth getting a special cloth? Or is my method ok?

Thanks in advance.

the instruction manual for my sammy DLP says to "only use a dry cloth". it doesn't mention any special cloth, and I'm sure that using a little bit of water is fine. just don't use any chemicals.

Default Microfiber cloth

The only way to clean it without damange is a microfiber cloth. you can get a small one at a camera store for about $2-$5. I use these to clean all camera lenes, my glasses, and any thing that i do not want scratched. I even have a larger micro fiber towel that i got from Rich Steves Travel for my travels. For cleaning i do not use any liquid on it unless you have a dried up booger on it

Default Make sure you clean the inside of your DLP

First off, sorry to those who have already read this post. I am just trying to spread the word.


Like many others, I had some shady/gray spots appear on my Mits 62525 screen a little over a month ago. Thanks to this forum and some other posts, I found out that it was dust on the mirrors inside the TV. Well, I convinced Mits to have my mirrors cleaned for me and they sent out a company yesterday. I was shocked at how much dust had accumulated on the small mirror. To say there was some dust on the mirror would be a gross understatement, it was completely covered with it. I have had my 62525 for around 8 months now and just recently started questioning the picture quality (PQ). I didn't know if I had just grown accustomed to HD and my lower jaw had finally reattached itself to its lonely upper half OR if the shows I was watching just weren't broadcast/filmed in the same manner.

Well let me just say that my eyes were not deceiving me and my jaw is once again on the floor. The PQ improved dramatically. I guess all that dust "fuzzed" up the picture somewhat.

Now I don't want to mislead anyone. Before the mirror was cleaned I could still tell if shows were being broadcast in HD. It was just that the HD programming was not as crisp as I thought it should be/once was. Lets just say that I will be cleaning my mirrors regularly.

Default Mits 62525

I also have a Mits 62525. I was wondering if your picture is clear. I am quite disgusted with the quality of pic i'm getting. I'm using my HDMI ports. Bought a Panasonic DVD-S97 and Panasonic Receiver SA-XR70. All hooked up through the HDMI ports. I have yet to see a clear picture without all the fuzziness. I bought my HDTV last month, so I know that dust is not the issue. I am now thinking of purchasing the DVE disk to help me calibrate my HDTV. Don't know if it is worth it, but I'm about ready to trade it in for a Sony 55" LCD HDTV. My brother just bought one and his pictures are VERY sharp and clear and he is going through regular Antenna (getting digital signals throught the air). What should I be doing or not doing?

My picture is crystal clear. My brother-in-law has a 55" Sony LCD and I think my picture is better. I am using an OTA antenna to receive my local HD programs. I am using Component cables from my Progressive scan DVD player and its picture is crystal as well. Are you getting your HD from an OTA antenna? Satellite? or Cable? Is your DVD player a progressive scan?

This might fall under the category of "Duh", but I came across this at my neighbors house. Some receivers have a switch on the back of them that enables/disables the DVI/HDMI port. My neighbors was switched off. Also, (just to make sure your are utilizing the proper Video input) make sure you are not running any other video cables out of your receiver OR into your TV. My neighbor had coax running into the back of his TV along with the HDMI. Well he didn't have the proper input selected on his TV, thus not receiving the HD picture. Quick and easy method.

Finally, if you are not aware, there are some other forums specifically for the Mits TV's. These will be a great place to post your questions as there are a lot more people who view them and have a lot more experience than I. If you would like the address to these forums I can post them on this thread.

thanks for the info....what are those forums for mitsubishi?

I use Surewest Digital Cable (in Sacramento, California). I got the bundled service which includes telephone, internet and digital cable. The Set top box is Amino (aminet100). My digital cable connects via component cables (Yellow, Black and White). It also has the capability of using the Red, Green and Blue cables, but at this time they do not work. I tried using the RF connection but the picture quality was TERRIBLE. Sometime near the end of this year, Surewest states that they will have HD programming available. Would ISF calibration be needed for optimum picture quality? I haven't looked that the details of the back of my panny dvd and panny receiver, only hooked up for surround sound and HDMI. Really, at this point, I "hate" my HDTV. Even watching my DVD's is not what I expected. My DVD player (Panasonic S97) is the newest model with HDMI. It is progressive and all that hoopla. Just which I could see a CLEAR picture. Even the station identification logos i.e., dicovery channel, HGTV, ESPN, CNN, etc.... are ALL FUZZY!!!! I set my HDTV and my receiver and my DVD player to the highest setting (1080). Still crappy.... I need some serious help!!!

I hate to tell you this, but just because its digital does not mean that your picture will be crystal clear. I have a standard TIVO through D-TV, which is a digital signal, and the picture is nowhere near the clarity of HDTV. However, the fact that you are having the same problem with your DVD's is beyond me.......especially with HDMI. As for HD content, are you in an area that can receive local digital stations (HD) via an antenna? This is how I get my HD programming.


Good luck

You are setup all wrong... Your TV is a DLP, and it is 720p/60 native set. You want to set your DVD and any other adjustable source to output 720p, progressive not interlace!

Your 'digital cable box' is connected with an 'A/V set' (not component) that is Composite video + stereo audio (Yellow/Red/White). Forget the RF over coax out of the box, that's the worst possible way to carry any signal. The cables with red, blue, green ends are Component cables, and carry a Y/Pr/Pb signal. The component output would have the best color of all the SDTV connections, and is the only one that can carry higher resolutions like 480p and 720p.

Thanks DubC...appreciate your helpfulness. I guess I could buy a HD antennae and just receive it off the air.

thanks also Rsawdey....I'm a newbie to all of this and I just want a CLEAR picture without all of the fuzziness. BTW, How can I contact an ISF calibrator, through Circuit city or Good guys or magnolia hi-fi, etc...? I also tried calibrating my HDTV with the THX optimizer on the "The Incredibles" DVD. Not much difference.

Here's a link to the ISF site... they have a 'find a tech' function there...

http://www.imagingscience.com

An ISF tech can perfect the color decoding of your DLP, but a DLP is immune to many of the imperfections that he could fix with a CRT RPTV... no geometry issues or convergence with DLP.

I think your 'Fuzzy' & 'unclear' problem comes from the sad fact your are viewing SDTV signals... an HDTV needs digital HD signals to show it's stuff. CNN & your other examples are low def & analog channels. Digital channels above #100 will look much better, cleaner, and HD is a whole new ballgame. But it's got to be setup & connected right. You should also be feeding the signal from an antenna to your TV's digital tuner so you could do PIP & compare the OTA & cable HDTV. You also have a CableCard option, you could do away with your cable STB.

But I think you may HAVE an HD digital cable box... what is it's make & model? You should be connected via Component cables (the Red, Green, Blue + audio) to see HDTV. You said "I set my HDTV & receiver & DVD to 1080i"... this really confuses me... you can't SET anything to change the res of your TV. It has a hardware res of 1280 x 720 mirrors, period. No extra mirrors will be made or destroyed for other formats. You need to set your receiver & DVD to output 720p to match your TV's abilities. If you CAN 'set your receiver to 720p' then your DO have an HD capable digital cable box... but HD MUST be viewed over the Component connection, A/V set or SVideo or RF are limited to SDTV.
