Yes -- it is a shadow or 3D effect. There is a word in black (for example) and you can see the same word again in "red" just behind the original. (Correction: I meant to say antenna instead of amplifier.)
If we open the inside front box to adjust the convergence on the control panel, the R-POS-V , etc do not respond. We do not see any green or red in the test pattern.
Yes, if you mean the control panel. The convergence adjustment on the test patterns do not respond to the control panel knobs.
Thank you for the reply.
The problem, and the reason that you cannot adjust it out using the Convergence MENU, is that the Convergence IC chips(there are two Sanyo STK chips in the set), have failed. This problem is very very common for all of the (3) CRT color gun sets that were produced in this era. Whether Mitsubishi, Sony, Pioneer, etc., they ALL use the same chips and all have the same problem.
The solution is to have the (2) Sanyo STK chips replaced (they are located by the Flyback in this set), and also inspect and replace as necessary any out of spec resistors, or open Pico fuses in the Convergence Circuit that usually fail as a result of the IC chips burning out.
Average cost for this type of repair is around $250 parts and labor if you hire a Tech.
