My sony hdtv the picture is like a3d effect with red tint flash focus will not work the crosses wont line up any solution or is tv shot?

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.

Picture is the color red

If it progresively got worse and worse then you need to change the coolant in the CRT tubes. If it just all of sudden one day was like that then the Convergence chips need replaced and associated pico fuses and resistors.

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
