1) I have a Sony KV-32FS13 that has a green tint in the picture. Does any oneknow how to access the service menu for this model? I tried other adjustments and I can't get rid of the annoying green...

Code 5 is "AKB error". AKB, or auto kine bias, is a cicuit that monitors the three color guns of the picture tube (red, green and blue) and tries to adjust them for proper color balance. If it can't, the picture is blanked (usually) and the timer/standby light blinks 5 times. When the color drives aren't balanced, you see a color tint in the picture like you're describing.

There might be a problem in the AKB circuit, or the picture tube may just be old enough that the AKB circuit has run out of adjustment range. If the tube is at fault, you should consider replacing the set. A new tube will cost nearly as much as a new 32-inch LCD TV, and you'll need to pay someone to install it and set it up. There are special tools required to perform the convergence which gets the color guns aligned with the face of the tube so they hit the right colors.

If you'd like to try tinkering with the service menu adjustments, this site explains how to access the menu and gives a list of settings.

My sony TV trinitron wega 42 inch picture is red. Is there any solution to remove the problem?

The problem with your TV trinitron wega is at the color adjustment section. It is located at the color board mounted at the back of the picture tube. There are variable resistors that represents the color pattern in the picture tube. Adjust the red color to low level to lower the red color.

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

I have a 54 inch Hitachi 57G500. The picture is now showing double on the blue spectrum color and auto magic focus is not fixing it.

Most likely this set has bad convergence amp ic's and some open resistors. This can be a very tricky repair. Check:
resistors RK42, RK46,
RK50, RK54, RK58, RK62
Output STKs IK04, IK05.
Hopefully this will help. Thanks for using fixya.
