Picture in concave on all sides and blue and red are off

Bad STK ICs they will have PN# on them STK392-570
Mats has them 1-800-628-1118
Replace Both ICs.

Install the Sony type 1 convergence repair kit available from www.tvrepairworld.com the kit includes the components and the cd with instructions.

Does that set have whats called a color wheel, if so that maybe you problem, and replacement is how you fix it.

HI, this is a failed convergence chip that is located on the convergence board. it will need to be replace ASAP. you can just replace the chip or , you can order a new board.

Replacing the chip can be a rough job if you don't have tech experience. if you are a fluid tech and you can solder and know your way around a circuit board, just replacing the chip will cost less. if you are not an experienced TV tech, i recommend a service call to the nearest TV tech to replace the convergence board.

This is what is known as convergence. a projection tube ussally has three picture tubes.. red green blue. they all have to align. the concave picture indicates complete loss of convergence or convegence power supply. First question on these sets Do you have the convergence option in the customer menu under setup. if you do not this is a indication of the common "FL231 fuse problem" and inexpensive simple repair. I have wrote and artilcle on this under my tips and trick section. If you do have the option then next does autoconvergence work. in you case i would not think it work. under blue and red manual convergence does the crosshairs move. if not then this is indication of convergence power supply board. if they move at all this may indicate a convergence amplifer problem.

Sounds like you have some bad convergence IC's not allowing the colors to line up properly.

need to change both convergence ICs STK392-560. you can get replacements at the following link with free instalation instructions with pictures.

your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.

Red and blue present, but no green = bad green CRT is
best guess.Remove lower front panel = adjust screen and focus
controls for best pix..................T.
