Setting color and focus inside case

Try cleaning the contacts on the lens and camera body where they meet with a cotton swab lightly dampened with rubbing alcohol.

ok..and so what is the issue here?

hello,

Thats need an over all cleaning in the circuit and resoldered all loss components and this will fixed the problems.

If you mean smearing when you say shadow then your problem may not be the convergence. The blue tube may be faulty(weak), try to play with the contrast and brightness levels and if that smear varies with the adjustment then your problem is most likely the tube, in some case there might be a problem with the screen supply(voltage) or the drive circuit. good luck

There are integrated ic's that control the convergence circuit, it generally requires qualified service personnel to repair this.

you need to adjust the screen voltage. behind the front grille and inside cover. a small black box 6 adjusters protruding from it. only adjust the the color counterclockwise that matches the problem in this case it's the green so look for the knob with "G" marked by it. there are 2 with "g" marked by them the row across the top of the box are for focus don't adjust. back the knob off untill the raster is blank with your input set to an inactive input, the picture should be blank and black.
when it is you have the adjuster close to where it should be, now change the input to an active signal and turn the color off so that you wil have black and white picture. adjust that knob untill you do have a truely black and white picture not too green or red or blue. go back to inactive video input and check that there are no lines of any color on the screen. repeat if needed. always adjust these knobs slowly the set will be watching you ! if your autofocus won't work now you have the adjustment set too low. check this function before putting back together again. these adjustments can be real touchy so be patient

If the red LED blinks 5 times you have a AKB error. It is caused by the CRTs trying to balance the color, and failing. Its an annoying problem that happens when the CRTs get old. If its just beginning you can balance or slightly turn up the screen voltage to the CRTs to remove the problem, if its in the end stages, the CRTs may need to be replaced. This is however, very expensive. If you are daring and safe around high voltage, pop off the speaker grille, open the front panel up and find the focus block. Don't poke around! those big red wires have 30,000 volts running through them! The focus block is a black square box with six knobs on it. Three are labeled screen, three labeled focus. You will see each row labeled R, G, B for red green and blue. The writing is tiny. Mark all three screen knobs with a colored marker so you know where they started. Then turn each one up slightly. If you have a picture, put it to a black screen or blank input. Turn each knob up just unit you see the color over drive and turn it back down to black. You want to set it just below retrace to maintain black level but drive the CRT fully. Setting this is hard but may fix an AKB issue.

The fact that you used the term "magic focus" tells me you have a Hitachi projection set. When the colors no longer line up on a Hitachi projection TV, it means that most likely one of the convergence output IC's has shorted out. Sometimes a shorted convergence output IC will burn up a low value resistor too. I have also seen a convergence IC crack loose from the board and burn up 3 low-value resistors. If your set is using the STK392-110 IC's, it is probably a good idea to go ahead and replace both IC's with the newer upgraded STK392-150 IC's. The output IC's should be resoldered / replaced and the circuits checked and realigned by a qualified tech familiar with Hitachi projection sets.

Each projection set has focus controls in back, usually they don't move or go out of focus unless someone moves it, but in your case if you open the back you will see a focus block with 6 knobs 3 are for screen,I would highly recommend that you don't move this. Look for the focus and you will have to set each with the one color. Cover the other two and adjust.

The screen/focus block assembly has caused problems with this model in the past. Sometimes it can be readjusted, other times replacement is called for.
