Contact Sony tech support, tell them the sequence

Hello Sarah!
There is no bulb to replace in your TV. Image is created by three CRT's and you don't want to replace them, just trust me on that one. It could cost you up to $1800 to do that.
All you can do is to clean lenses of those CRT's. You have to disconnect TV from the power outlet and remove rear cover. Using very soft brush and vacuum cleaner remove dust from Red, Green and Blue CRT lenses. Do not use solutions unless you got something special for optics. Solutions will leave film on the surfaces. That would improve brightness and contrast of image.
To adjust focus front grille have to be removed. Than central piece cover held by 5 screws. Behind it you can locate black plastic "box" size little smaller than cigarette pack. there are 6 adjustment "screws". Three of them are "screen". You don't touch those. Another three "focus" there is one for each color. Turn TV on. Hit "menu" button. And adjust focus for each color separately. If menu goes away hit it again.
This is the only improvements you can do.
Everything else will involve humongous amounts of cash.
Good luck!
Russ.

Depending on your TV, you may have a Color Temperature (Color Temp) and/or Hue setting in the menu. Use these options to adjust the picture to the setting that best suits your viewing preference.
If your TV has a Color Temp setting, you will normally have the following options to select from:

• Cool: Gives the picture a cooler, slightly bluish appearance.
• Neutral: Gives the picture a neutral, more natural look and appearance.
• Warm: Gives the picture a warmer, slightly reddish appearance.

If your TV has a Hue setting, follow the appropriate step below to make adjustments:

1. Move the setting to the right to reduce the reddish appearance.
2. Move the setting to the left to reduce the greenish appearance.

The convergence amps are the big STK's*** located possibly on the G-board in the sony. It is very difficult if you are not familiar with components and soldering, You can buy them at MCMelectronics, bluestar-online.com, Tritronics, VanceBaldwin.com, etc. Diagrams are online at fixya.com on the rightside of screen.
