Just replaced IC's but cannot adjust Red horizontally through Service Menu

I just replaced the convergence IC's and Green and Blue lined up perfectly! however, when i try to line up the Red through the service menu, it seems as though none of the horizontal adjusts make a difference (such as the CENTer function and the SIZE functions). Very confused... What could cause this? Thanks. Michael Brown

Solution 2 was it. Thank God. The yellow Circuit Protector was my problem. I actually traced it back last night a couple hours after I posted this. After an hour of tracing circuits and going blind from looking at the schematic. Haha.. Thanks

If your TV has a 2 part converge, basic and advanced to do small blocks across the screen, you need to go in & do the red with via adv. mode, then save to memory. If you cannot get RED tore-align you need to go back to the IC's and check the small low ohmage resitors in front of the chips, usually 1 ohm - 220 ohms and are fisible type. Physically remove one leg of each resistor & check. A 1.2 ohm measuring 1.4ohm can cause the tv not to converge. Look for burnt or discolored ones as well. If you find them & replace, you will need to replace the IC's again.

It has tripple vision and looks like a bow tie.

hi, sounds like a convergence issue. try this...

Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

Enter the menu on your TV. Use the remote control and bring up the menu.

Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."

Select a color. You will have red, green and blue to choose from. Do each one, starting with red.

Press "Enter." A crosshair pattern will appear on your screen.

Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.

Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.

Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.

Repeat these steps for all colors.

good luck!

Need code to enter on remote to engage multipoint convergence adjustments.Need save proceedure after adjustments are made & exit proceedure for RCA Projection TV Model # HD52W59, ITC 222A

Hello,

To get the code to enter on your remote to engage multipoint convergence adjustments, you need to contact the rca customer care for that, you get them your model number and they will get your code for you.

To process and save the adjustment made, follow the steps below;

Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.
Enter the menu on your TV. Use the remote control and bring up the menu.
Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
Select a color. You will have red, green and blue to choose from. Do each one, starting with red.

Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.

The Screen looks 3D & Colors don't line up on my big screen????

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

Can't control red convergence on VS-45607

The STKs are three channel ICs they each control horizontal and vertical of one color the third channel controls part of green and the other half of green is controled by the other ICs third channel. Its customary for the Ics to fail and only have one channel bad in the IC. However its recomended to change both because of the bad Ic having green it can actually weaken the other IC and that one will fail shortly.

Convergence

If the red isnt responding via the remote you will need to replace the STK392-110 Ics as the service menu adjustment will not correct it 100% due to the IC being faulty and the red and half the green is controlled by one IC and the blue and other half of green is controlled by the second IC so without changing both ICs the set will progressively get worse. Both ICs are stk392-110. You can get replacements at the following link along with instalation instructions

How to adjust the green convergence?

Hi, If the green crosshatch lines are bent or curved then you have an IC failure, Green is the reference so it can`t be adjusted with your remote, the correct procedure is to move the red and blue on top of the green to make the crosshatch white, As I said if the green horizontal or vertical lines are not perfectly straight then it needs repair not adjustment, BMW Rider
