My tv worked great until I moved it to my son's room. After hooking it up, the picture was dim and the lettering, logos, channel #s, menu, anything with words, including the satelite menu, is blurry. After messing with the controls, I got a decent picture, but couldn't help the blurriness. Thanks....

Before you buy a new TV go through all the TV menu options to see if it has automatic dimming depending on the amount of light in the room. If it does it may be malfunctioning and turning that feature off may fix the problem.
Sounds like a coolant issue with the CRTs. Look into the lens of the green and blue CRTs and you should see what looks like bacteria if the coolant nees replacement. Usually the green and blue get contaminated which dims them and makes the red become dominate and the picture will get dim and out of focus.
This is probably a combination of 2 things. In both causes 1 and 2 below, I would suggest checking the TV with a BluRay Player with BluRay disc connected using an HDMI Cable. If you complain about this, then the TV is probably not that great. Expect a $200 jump to a better model at the least (but this depends on what you have now). Honestly, this is fairly normal and wont change much with the next TV.
CAUSE 1: Motion BLUR
Motion blur occurs when fast moving objects are displayed on LCD TVs. Basically, it takes time for the LED lights that make up the picture to turn ON and OFF, when and object shown on the TV is moving faster than the LCD TV can turn these lights ON and OFF, you see the trail left behind as the lights dim to OFF. This look like blur because you see the current image and the trail of the old images. 120HZ and 240HZ LCD TV are supposed to improve this but honestly, they are at times 300+ dollars more and not really worth it. Very little difference except in some few cases.
CAUSE 2: Digital TV
Digital signals are hit or miss. Good or BAD. If you are watching Cable, Satelite or Antenna; it is likely you are seeing some BLOCK NOISE. This block noise is caused by missing information or Noise in the video signal. This will cause the picture to Pixilate (you see blocks and things start looking blurry too). This happens with poor signals. This also happens with the HD channels when they have more information than bandwidth (more data than that have space to send it...image shoving an elephant into a VolksWagon Beetle)
Try it again in the original room where the TV once was. If the channels from 47 and up are back to normal, its a cable signal issue that the cable company must resolve. Its possible that the installer may have driven a staple thru the coaxial cable or did not correctly attach the fittings.
One of the most common faults with the phillips rear projections is the coolant in the tubes. That can and will make the picture very dim and can cause the brightness and focus controls not to have much affect over it. Please respond to this same post with your model number and I will check to see if their are any other items that could cause that symptom.
The screen probably needs to be degaussed, which will require either a degausser or a technician. Try turning the television off, and then unplugging it from the wall outlet. Then replug after 30 seconds and turn it back on. Also, try plugging any cables from a cable or satellite box into another set of in-ports on the back. If the problem persists, the screen needs to be degaussed.
