Blurred picture red and blue shadows


Hi,
Please run the convergence feature on your TV. Its giving you double image because the red, green, and blue guns are dis aligned. By running convergence it will realign the guns properly. You need to run the convergence feature at least once a week. Please note this is only for CRT rear projection TV's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to refer to the manual on how to go about it
Good luck!

The colors are red blue lime green and the screen shows a double picture


Hi, The most likely cause of this problem, the color guns is out of alignment. Rear Projection Televisions often go out of alignment over time. Your television "should" have an automatic alignment function within the Television Setup Menu. Since you did not provide the model number, I cannot give you specific instructions on how to re-align the unit. Check the user’s manual or contact the Television for instructions on how to automatically realign your television. Thanks, Mike H.

Color alignment problem


You will need to put the unit into wahts called service mode because it will have to totally realigned since you change the whole module you changed the chip that had you stored memory setting for convergence called an EEPROM. here in the shop I would unsolder the old EEPROM and put it on the new BOARD. Also on most models you don't have adjustments for the green you have to move red and blue to match green. Imay want you to describe again to me what you can adjust now with the new board in the unit can you move all colors left right and up/down

Horizontal Color alignment will not align


Green color means that there is contanimation from the blue and yellow inks. Try to look inside the printer to where the printhead rests when not in use and see if there is alot of ink there. There may be green ink on the sponge there that may be attaching itself to the bottom of the printhead.

Hope this helps!

The alignment you need to do to realign your TV is called "setting the convergence". All projection TV's have 3 color guns (one red, one blue and one green). When you move a TV or josstle it, these guns can get misaligned and need realignment. This is definitely something an average user can do (you don't need a TV repair man to do it for you). It is a very simple procedure (most TV's have an option in the menu to do this, just look for convergence adjustment). What you want to do is use the remote to get all 3 colors to overlap completely (you can only move one color at a time). Some TV's have squares on the screen that you must align, others have plus signs. If you can't find it in the menu on your TV or if you can't figure it out on your own, you can look for a manual at Hitachi's website that will walk you throught the process for your TV.

Color guns out of alignment


It sounds to me like the convergence amps themselves have failed. Ic7001 and Ic7002, both are STK392-110 Sanyo built Ic's and not an expensive job for a qualified shop. When shopping around for a shop to repair it ask what they charge for replacement of the convergence amps in this unit. And take the unit to them to save pickup and delivery charges...
Have a great day!

Conversion problem


Has it been moved latley? is there any auto align mode? i know the lenses can bounce inside there during a move and it can throw off the focus. If there is no kind of auto align it may need serviced. Usualy they have to come out and realign it using special tools. The tools display a cross on the screen in each color and they adjust the throw of the guns that refocus all the colors to the center till it becomes one solid color. The panel drops down from the fron and you adjust the pots with a plastic tool that realigns the guns. There may be a mode in the settings to display the image you use for the alignment. This is a common thing and i think they recomend it be setup at the home and not moved after its setup.
