LOML and I bought a new LCD 55" TV from Sears last night. It's a Samsung flatscreen on sale from $2900 to $1900. Man, we didn't realize what we had been missing, what a great picture. We have a Mitsubishi 65" DLP TV that is about 5 years old but living in the desert with dust bunnies and critters, we are assuming the DLP needs some matinence. The picture is dark and there are dark spotches projected onto the screen from behind (if that makes sense), on the screen. We're thinking there is dust and cobwebs on the projection lantern. Does anyone know how to clean them or do we need to take it to a professional, which is hard to come by in our area!

Becca,

I had a large box TV, which is, what I assume you have.

Unplug, take off the back and you have a big empty box with a reflective surface. I would use my compressor and hit it with air. Work up from 20 poundsish. Mine was a kind of aluminum foil surface. But I would expect more of a front surface mirror, so I would not touch it with anything that may make the dust scratch the surface.

I yield to anyone who actually KNOWS what you are talking about and may find my answer totally unrelated and useless!!

I had the same 65" DLP.......do the same I did......call Sears......

I know, I cheated, I had a service contract. Yours needs a thorough cleaning......you'll really notice the difference once it's clean and adjusted!

I had mine for about eight or more years.......they finally couldn't fix it after three tried......got a brand new one.....the largest Sony Bravia flat screen. Now I have my front room back.

Sears didn't want to come and pick up the old one and told me that I could do with it as I wanted.......sold it to a friend.....bought my 'Pen Wizard'........what a deal!!!!

We have a 54" Sony. We had the bulb changed after three years of use. Two or three months later we got this big blue splotch and now some tiny blue holes. The advice I have been getting is to take the lower back panel off, clean the bulb, look for dust and clean. Has anyone else had the same issues with their Sony?
 
I have a 3 year old 55" DLP sony. I just replaced the bulb about a month ago. I have never had any shadows or color problems. But before the bulb went out, it was darker, when I changed the bulb, it was a difference of night and day. When the bults get old, the picture does suffer. But with that big fan running in the back on the bulb, I do clean it about twice a year, and it is pretty dirty.

Hubba hubba, I am going to get brave and take the sucker apart when it is cold. It has to be the issue. We have had allot of home improvements (room additions, dry walling, etc.) that threw dust into the air. This would be a great remedy. Thank you.
 
I have a 50" Sony Grand Wega. It is 6 yrs old and has the blue blobs on the bottom that you mention, jgrden. I have done a lot of reading on the net and everyone says the light engine is going bad. The colors on my TV have progressvely gotten worse (purple tinge) as well. I looked into a replacement light engine and it was anywhere from $400 if I send mine in and wait 15 days to have it re-built to $1,000 for a new one. Not gonna even put $400 into a 6 yr old TV so it looks like I will be looking for a new one soon.
 
I bought a 20 inch Sears TV for 500 back in 1998...It's still running strong in the bedroom. My 32" tv in the main room only has one input, and it takes a few seconds to 'heat up' before it'll show a picture...if you turn it off, it sometimes turns itself back on again shortly after...

Might be time for me to shop around too, but man, I can't imagine spending 2 grand on a TV!
 
Believe it or not, I went to walmart and picked up an Olevia 47" lcd HDTV in 1080p for just under a grand. My girlfriend and I got it for eachother for our birthdays last year. The picture is amazing, never a problem, and the price is right. The main thing is, you have to look for 1080p so it is setup for future cable or satelite upgrades. I have to be honest, I was worried about buying this because it is a brand I never heard of, but I got a samsung first, got it all hooked up and it didnt work. I had to bring it back. Anyway, as of now, I havent heard anything bad, and there are nothing but great reviews about the Olevia brand tv's. Something to think about.
 
If you can't resolve your problem...turn a pretty wall hanging for the spot!!! HA..how can you have that much wall space available in the home of a turner???? HA!
 
That's what I love about this diverse group of ours, lots of info and or opinions. LOML and I will take off the back of the DLP and blow it off softly with the compressor. If it works, our daughter will receive a big TV.

Our new one is a Samsung with the same 1080p thingy, superb picture. We feel like we are there watching things while they are being filmed.

Thank you everyone for your help:biggrin:

Note to self, never buy another DLP! JMHO!:bad:

I actually prefer the DLP over the LCD. I have heard more issues with LCD and the repairs are even more expensive, not that DLP is cheap! Them bulbs are insane. My biggest issue with LCD is that you lose your view from the sides. Clarity wise though, I don't notice that much difference. Of course my screen is 16 foot wide. hehe, kidding..those monsters for the house are split into multi screens which I can't stand. Mine is in the 50 range. To clean my bulb, you just turn a knob 1/2 a turn and a door opens and the bulb is right there in a big box.
 
You make it sound easy. I'll let you know. Can't be tomorrow though, all my muscle car programs are on in the morning.
