based on model number it could be cleaning or another issue--with color turned off what color is the screen? On this set with back removed also clean the 3 large lens as if dusty picture will be dull and somewhat dark.
ll projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.
CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
This mite sound crazy but it is time to change the oil in your TV. Yes your TV has three seperate picture tubes on the inside of it. A red tube, blue tube, and green tube. Each one of thses tubes has a clear oil that the light shines through. Over time this oil gets cloudy and distorts the light thus dimming and fadeing your picture please have a tech change the oil in your tubes.
There is clear fluid in the 3 color tubes to keep them cool. The fluid is simular to antifreeze. Try an ebay search for "TV COOLANT". You have to make sure not to spil ANY on your board or you will be very upset. This is oil based and will ruin the board "CAN NOT BE REMOVED". What clouds these TVS up is bacteria growth. Normally it can not survive under the red lamps. Blue is the main one to cause this. To check for growth, you have to look in the lens when it is on. You will see small spots. Once open you have to wipe and clean the spots off before adding new fluid. Fluid is very cheap. A shop will charge a couple hundred to change each tube. Use 100% silicone around both sides of gasket before resealing. Also lay a plastic garbage bag under the lamp for a few days with a towel on top of that. IF you have a leak, this will keep it off your boards. A trick to doing this easily is lean the Tv foward so the lamps are level and use a turkey baster to **** ALL the old fluid out. You can also use any type of suction tubes.
KP53S65 is a rear projection Sony several years old--It is not a DLP and does not have a bulb--it has three picture tubes---if the set has not been serviced in a long time here is what you can do to try to improve it:
1.) Unplug set 2.) Remove back cover 3.) You will see 3 black lens (one for each tube) 4.) With a paper towel (spray glass cleaner on it) clean the dust from the three lens---if they have not been cleaned in a long time and have dust on them the picture will be darker and less distinct.
5.) Replace back cover and plug set in to see if this has helped----I have seen some where there was so much dust on the lens that it looked 50% better after just cleaning the lens--depending on area you live in--should be cleaned once a year.
I do this here for free so if this has helped you please take a minute to give me a vote here.
has it been inspected for proper lens and mirror cleaning? or by cloudy you are referring to some kind of weak signal. when the cleaning is needed the picture comes in dim but with definition and the correct color, tint though gives the impression is to bright or very low in contrast.
Most of the time this is caused from cloudy coolant (ethylene glycol) which is used to keep tubes operating cool. Tubes must be removed from set, usually blue and green tubes only. Then it must be drained, cleaned and refilled. It's a messy job and usually can be performed by a service center for 200.00 to 375.00 total. Just the liquid can cost 50.00 to 100.00 and this is fairly common on philips big screens. Hope that helps.
i,m not a tech but i,ve been told by a techinican that those tubes do have fluid and it,s not an easy fix to change the fluid i was told the tube has to be removed and a tech told me it would run around 200.00 by the time the tech removes it puts the fluid back in and reinstalls it and after it,s reinstalled the convergance has to be reset that,s what realigns the colors back to their correct position and i,ve heard this isn,t an easy job so i,d probably get a techinican to fix it but that,s up to you someone might have an easier opinion but the tech i talked to is one of the best thanks and maybe you can help me i have a blue tube on my big screen tv that wont light upcould you give me some insite as to what you know about a projection light that you said that may need changed think that may be my problem your welcomed to call me about this at 270-566-4327 anytime soon as possible thanks
