HCL652W picture faded will bulb replacement fix this

I would say that it is not worth replacing the bulbs. I had a similar experience with an old rear projection TV like that and I just cleaned all the dust out of it as well as I could. i cleaned the back of the screen, the mirror that the image reflects off of, and the bulbs themselves. I used a dry micro fiber cloth so as not to scratch anything. doing this might help you some, but if it is working and it is bright enough for you after a few minutes, I would just live with it until you can upgrade to a newer TV.

I have a Pioneer SD-532HD5 Projection TV in which the picture is clear but dark and the colors appear weak- better color if a cartoon video. I have adjusted the contrast to max with minimal benefit and...

not convergence issue from description and if lens did not help when cleaned have a close look at the mirror as well to make sure not grimy or dirty, usually can peek in from the rear and up to examine it.

From the age of the set it could also be the tubes getting old but that would be unusual as have seen this set before and the tubes do not usually fail---problem if in the video circuit presents some challenges as a lot of parts for this set are no longer available.

take a look at the mirror with a bright light to see if smudged or grimy---looking straight at it may not show the dirt.

I have an older Pioneer rear projection TV that has never been cleaned, model SD-P50A5-K. Can you give me the basic cleaning instructions and the do nots for this TV.

Unplug the TV for safety - even unplugged, there is enough energy stored in the electronics to be very dangerous.
The bottom speaker grill snaps straight off. There are a row of screws under the screen around the screen bezel that must be removed. The bottom of the screen will become loose and the whole screen assembly slides up, like opening a window (there is a bracket under the bezel at the top of the screen that the bezel slides off of.) My screen took a lot of effort to disengage the top bracket - careful not to break anything!!!

Once the screen is off, put it safely aside. There is a mirror in the back that can be cleaned with a damp cloth (not dripping wet!). Remove a little dust at a time and keep washing the cloth out between cleanings. Be very gentle. If you push on the mirror it could break If its never been cleaned there is sure to be a lot of crud.

Below the mirror are three colored lenses. CAREFULLY use a clean lightly damp cloth to wipe each one. Don't mess with any of the adjustment screws and levers on the lenses.

Before putting the screen back on the TV, carefully clean it with a damp cloth too. Slide the screen back over the top bracket, put the screws back in, and pop the speaker grill back on.

Its a good idea to readjust you convergence too.

When I cleaned my set, I was amazed at how bright and sharp the picture was!

Be Careful!

Tv color not bright enough and just replaced lamp

Clean the small mirror in front that projects the image onto the rear mirror. The Rear mirror always stays good but the front small mirror gets dusty and the colors and bright levels get affected and appear dim.

Mitsu 65" DLP-picture seems washed out

Most likely cause of your trouble is dust on the small mirror inside you set. Your DLP set has 2 mirrors not including the DLP chip itself which has about 500,000 tiny mirrors. The 2 mirrors reflect the DLP chip image to the screen you view. The first is the main suspect it's about 4inches by 7inches. It's mounted on the bottom center facing backwards. This mirror faces slightly up and somtimes after time dust, smoke, dirt settles on it . The second fills the space of the entire back of the cabinet but it faces down and takes alot longer to get dirty.
The compartment is sealed but dust seems to find it's way in. If you remove the screws that secure the screen assembly from the top , sides and bottom. Make sure to have a friend available the screen assembly is delicate when it's not mounted to the cabinet. You can remove and clean the mirrors. These mirrors are glass and you can use glass cleaned. Don't use glass cleaner on the screen it's plastic. You can clean it if necessary with plastic cleaner only. Probably not needed.
Good luck.

There is only one brightness bulb for your tv. You have the main bulbs which run the color for the Tv and then you have another bulb which runs the brighness. Typically it is a flourecent bulb inside which does need replacement now and then. Check tje specks on the tv's web site and you should be able to get the model number of the bulb from them and you should be able to purchase it from a repair shop or from online
