The projection fluid is more than likely glysonal and is not safe to be handled without proper precautions

Solid green light but no picture


I think this is a projection set. Sonys are called SXRD type lcd projection . Little diff from DLP types. But they do have a lamp. Unplug set plug back in then turn on . Count blink code. Check lamp also. blink code is 2 digit code. Code will give clue to failure.

My sony is turning on and off when I turn it on. The picture and sound appear and disappear. What is wrong and do you have the part..


Hi,

The most common cause of picture disappearing and returning in a Sony LCD Rear Projection TV is a faulty bulb. Replacing the bulb is the first step in troubleshooting this type of problem in KDS-60A2000 and all other Sony Rear Projection LCD TVs.

Sony Lamp Gallery
shows all Models and Lamps for Sony Rear Projection LCD TVs. KDS-60A2000 uses XL-5200U Lamp.

My Toshiba 65H81 65" rear projection TV's picture


You do not have individual lamps in that model. You have 3 individual picture tubes of which I don't believe they are bad. They have fluid in a reservoir that becomes cloudy after time and needs to be replaced, however this is something you cannot do yourself. I recommend you call a qualified technician to take care of it for you.

Hi, I have a Hitachi 43FWX20B and the picture shows no red. I opened the servce cover and the red lamp does not light up when the TV is powered on. The other lamps light up just fine. I think the red lamp...


As you said your set uses 3 crt's red.blue and green.. not lamps.. If the red is not on it could be for several reasons other than the crt itself. From the driver ic located on the crt driver board attached to the neck of the red tube. It could also be the high voltage block or the anode lead going from the hv block to the crt itself. These carry a hefty voltage and will knock you on your but and make every filling in your mouth light up lol.. I recommend you having someone experienced check it out. As for the fluid, if the picture was good before it went out then that wouldnt be something to worry about. Removing the tubes to refill with fluid requires a massive alignment job afterwards.

Ihave a Philips 50PL9126D tv and I just replaced the lamp because the picture was very dark. I can see the picture but it is still somewhat dark, bright in the middle,dark at the edges. I tried to adjust...


Sounds like you may have the wrong lamp. Make sure you purchased a Philips lamp that's 100% compatible with your television model. Philips pioneered that lamp, so naturally they make 100 different types for DLPs and LCD projections.

You may have an elliptical lamp instead of parabolic. The lamp for your TV should read P22h.

Cloudy picture on Philips Rear Projection TV


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.

THE COLOR ON THE TV IS STARTING TO GET ORANGE


The picture is formed from three lamps in the base of the TV. These lamps have a fluid filled lens on each of them and the Glycol in this fluid degrades after time. This fluid can also have a mold or algae growing in it. Check the lamps visually first BUT DON'T touch the driver circuits ( this would be very bad for you) with them turned on and off. If you need to change the fluid, be very careful as leaks happen very easily. If you get any of this fluid onto the driver board it will damage the tracks etc VERY QUICKLY. You must replace the fluid with the correct fluid at the correct level and amount and wash your hands afterwards as Glycol is a poison. I do not think that this is an electronic fault as the orange tinting leads me towards a fluid issue.

Projection Lamp for Philips 60PL9200D/37 TV




More than likely the problem is the CRT fluid and not the tube. Do a few google or fixya searches on CRT fluid and to get an idea of what it looks like when it gets cloudy.
