I'm seeing red, literally, after buying this set for $300.
I bought this tv from a friend of a friend, just 1 week ago. It worked great when I first got it, so I thought I got a great deal!
Yeah, it's a little older, but I don't care about having the latest technology, I just want a tv that I can see from the other side of the room.
This morning when I turned it on, the screen started displaying everything in red, as if the red gun is the only one working. I'm hearing that everything for this tv is NLA, and this just makes the red really stand out now! I pulled the back panel, and all three guns are working, I held a peice of thick paper over the guns, one at a time, just to block the light beam. The Green and Blue guns are working, but I don't know how to adjust the individual rgb color level strength, or if the strength can even be adjusted. To make matters worse, I don't have a factory remote.
I don't know nothing about these older rear-projection tv's, but I am a competent computer builder, and I am skilled with electrical/circuit-board repairs.
If someone can point me in the right direction, for manuals, hardware, or just simple advice on this issue...
I would greatly appreciate it!

Re: I'm seeing red, literally, after buying this set for...
Through the front of the tv behind the speaker grill and behind the panel in front if the CRTs there will be a square object with 6 knobs you can turn. grab a flashlight and twist the RED SCREEN control to the left until the red is less prodominate. make sure you still have some red because then the picture will look purple. that adjsutment is called G2 or SCREEN control adjustment. try that be careful though because tooo far one way and the picture might start to blank.
make sure that you check all connections coming from your video sources also.

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.
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.
Common Problem #2) 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.
It depends on what the problem actually is; are the streaks colors like red or blue outlines around lettering etc?
The more you tell me the better I can help. I will post a photo or two of what convergence problems look like. This set is also prone to another problem, on a blank video input look at the screen: you should only see Video 1 (etc) and if you see faint curved lines (red, green or blue) and or the back ground is also wrong color you have the second problem.
let me know which it is.. If this information helped you rate this solution as very helpful as I do this here for free.
I decided I would try to repair it even though I didn't have any soldering experience and literally had to go buy a soldering iron. The parts costs me $26 including shipping and it took me about 4 hours to repair. I was so happy when I pressed the power button and my old friend came back to life. It is really simple to do and if you have experience you could probably finish in less than an hour. I hope this helps!
Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.
I bought a LG 39" flat screen 6 months ago. TV has been working great until this morning. Power comes on for about 5 seconds and then cuts off. Have checked all connections and have unplugged from wall to reset, NOTHING!! And a brand new TV!! Any help would be great!
After 11 years???? OMG This set is a tired pup and should be put to reast. My experience with older sets and your complains are all capacitor problems and is only gonna get worse as the first time around repair will take several capacitors to repair. This set has no user serviceable parts inside so you should not attempt a repair suchj as this on your own.. This repair if you decide to go through the first time will be About 300 to 600 bucks the first time and cost will continue to raise till the sets put to sleep. Good luck
