Convergence chips replaced, tv powers on and no picture


You have to replace the chip with the same kind, or at least crossed referenced, but still exactly the same but diffrent manufacturer.

Rcs hdtv multiple images


The problem you're having is due to the failure of the convergence amplifier circuit. In that circuit are some components which amplify or control the signals to the dynamic convergence yokes, which line up the red green and blue images to superimpose them over each other to create a proper colour picture. When you get a failure in that circuit, it no longer aligns the images properly, and generally you get what appears to be badly set geometry in multiple colours. In some cases you will also get a problem with the part of the power supply that supplies the convergence amplifiers, or the digicon, which is the digital convergence control module.

Picture has a blue shadow


Hi,
Seems convergence out IC is fried in TV so it gives blue shadow.

Re: 43FDX01B blue convergence issues


Ditto CTF1800's comment....Check RP-41 1.5 ohm 2 watt and
other low value resistors near IC's mounted on large heatsinks.

STK392-110 original convergence IC's can be upgraded to
Hitachi # CZ 01341 new number STK394-160E for greater reliability.......Hitachi also has an IC / resistor kit # X480295,
but I don't change good resistors, only the bad one(s).

Practice good visual acuity technique and ask questions!.....T.
