The symptom is not an indication of a convergence problem,straight forward the blue is missing,the pictute tube is not firing up or the color driver are not active and the blue color is not being processed,check the blue picture tube to see if is on sometimes you can see all three gunds from the side of the set.You should seek assistance from a professional to diagnose the problem.

I thought i might need a lamp for my mitsubishi tv--model VS 60607 when my tv is fuzzy when turned on.should i simply replace the lamp or is there something else i should try? thank you!

This TV is a rear projection television and does not have a lamp. It has three CRT color guns (Red, Blue, and Green). You have a convergence issue (the red, blue and green color guns aren't aligned properly) and it doesn't sound like a very big one. You should be able to adjust this through the CONVERGENCE Menu in ADVANCED SETTINGS.
More details can be found in your manual, here. The model number isn't exactly the same but I'm sure the process is identical or really close. The other option would be a bad IC (integrated circuit) for the convergence control. This is unlikely unless your picture looks something like this: captainhawk1_15.jpg

My TV color has yellow, blue and red shadows n the picture.

Enter Service mode.. Press Menu -0-1-5-7 in quick succession . From there select the convergence option. You should see 3 crosshairs -Red, Blue and Green. Green is fixed but Red and blue can be moved. Align both of them with green and see if the issue resolves. If not Try moving them around and see if the problem is cleared. If not you may have the inevitable convegence IC problem and the IC needs to be replaced. Let me know if that is the case and I will give you the procedure.

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.

Both of these answers are incorrect but the first one is very close. When the lamp door warps, the picture keeps proper color but looses brightness. The second answer is just completly wrong. This set does not have a color wheel.
This set needs a new optical block and cleanning. The picture will be good as new with that. The Sony tv's are not DLP, a Texas instrument chip technology. A Digital light processor has a lamp, a color wheel and a optical chip that works together to produce the picture. A Sony has a lamp but uses a combination of mirrors and light filters to send the lamps light through 3 LCD's. The LCD's are about in inch in size for each color red, green and blue. They have millions of tiny mirrors inside to make up the picture. This method creates a better black in the video and eliminates the rainbow effect, better than a DLP but makes the LCD's work harder and heat up more because of location to the lamp. the most common problem is the blue (The closest to the lamp) starts to loose its ability to pass light so the picture gets blotches of brown/yellow because the blue is missing or reduced. The light filters collect dust and because the light is so bright when it passes though, it actuly burns the image of the dust into the filter. A home that is dusty and people smoke in will ruin one of these sets in 1,000 hours of use. A clean smoke free home will see over 4,000 but this was a problem with design and is most likely to happen again and again. Hope this help and good luck.

Color issues with Hitachi 60V715

You likely have a problem with your Optical Engine. It is very expensive to replace and should fix the problem. The lamp cannot cause color issues. You may have dust/dirt contamination in the engine and it could be clean by a servicer or technical person. The blue LCD panel or polarizer may have failed in the engine giving you blue and yellow (lack of blue) type symptoms.

Philips Blue Shadowing

If you have not already done so go into the picture menu and set the convergence. The convergence is the angle at which the three picture tubes meat at a given distance. The tv will have at least 3 and up to 64 convergence points, and those 64 can be set for all three colors. This can be tiresome but I'll be it will solve your problem. What your trying to do is get the color in the cross-hair so you cannot see the color behind the target. On top of the fine setting for each point and color you will probably have 3 gross adujustments for blue and green and maybe red. These adjustments will affect positioning, like what you are discribing. You should do this at least every month, the thermal cycleing of the lamps is what will cause this to creep out of adjustment.
