    CTR1800, I appreciate your reply to my problem. I do get a picture. It seems the red and green are out of alignment. Wonder if you can tell me which board is the convergence IC board? I contacted Sony Tech Support and did not get any help on this. Thanks a lot.

    I am having a problem like this. The red and green seem to out of line a bit, and fine print is hard to read. I could really use some help, thanks Josh F.

    you should look for IC with the numbers like stk392-???
    most common is stk392-110 replace both ic they will be attached to
    two big heak sinks might be board G, also check the 1watt resisters close by they are small resistance like 3.9 ohms should be 6 of them.

Replace your Convergence ICs they are Big Black ICs and will have part number on them,
STK392-110. You also need to check the pico fuses in front and back of ICs they will look like resistors Green or Yellow but are fuses 5amps-7amp pico fuses.

I was watching my HCL4715W TV and the picture

It sounds like one of the convergence Ic chips is bad---you will need to locate and replace both of them and look for any damaged parts around them; there usually are two pico fuses in this area, one for each IC. The fuses do not look like glass fuses--they usually are green or orange in color and will have the amperage marked on them and on the top of the circuit board.

Dark , blurry picture

MTNESTR, My guess would be the FBT loc.TH01(flyback transformer) Hitachi p/n#BW03004 which would be far less expensive than replacing the entire deflection board... A shop could ring test the FBT to confirm the failure. I do know the FBT in this unit has an internal resistor that is prone to failure. It is in-line with the focus block and if it's open it would explain the blur and lack of screen voltage to light the crts properly. The deflection board is about $290-$350 plus shipping and a FBT is somewhere between $60 - $90 depending on the supplier. Hope this helps! Bill
