First I replace the ICS t.v. still showed red, blue, green. Took it back apart found the upper 5amp fuse on the G board bad replace it. Put the t.v. back together, Still didn't work. Took it back apart to find the same 5 amp fuse blown also, a 3.15 amp fuse is blown. My next step is thowning the t.v. in the trash cause i'm not payin $400 to get it fix. Can someone please help me!

Re: Red, Green, and blue
Those fuses usally blow when the ics are shorted. Are you sure that you were careful soldering them in and did not have any bridges? Also you make look for some resistors that have changed value on you after all of this.

You need to replace Both STK ICs . They are Big Black ICs and will have PN# on them
Mats has ICs 1-800-628-1118
Also check the Pico Fuse in Front and back Of ICs they look like resistors ,But will be Green or Yellow 5amp, 6amp, 7amp.
Your TVs red colour output section has the trouble. There is no red output at the red cathode of the picture tube. The red, green, and blue output sections are on the picture tube base board. In some Philips model, these will be consists of transistors, and some has an IC or Tree ICs for three colour output used. You just open your TV, measure the voltages at these three cahodes. There will be markings on the printed circuit board for these cathodes marked as [Rk,Bk and Gk].
In your TVs case the voltage at the Rk marked pin will be higher that the other two cathodes. This can be caused by an open drive transistor or an Ic whichever may ysed there. If it is transistor, just replace it with a same type and number, as in the ace of ICs the related Ic, must be replaced. If only one Ic is uded for red, green and blue outputs, that Ic must be replaced.
If you need any more assistance, feel free to get me through Fixya. Ok.
From what you have said , Replace both of your STK ICs they are big black ICs will have part number on them example STK392-110
Go by the number printed on them if they are 110s use the 180s they are better ICs Mats has them for $10.95 each 1-800-628-1118
Also go to this website/use Google Encompass Parts Distrubtion
1-800-638-3328 sometimes they will have free service manuals you can print out.
Another thing you need to CK pico fuses they will look like resistors only they are green or yellow 5amp/ 6amp fuses Look in front of ICs and some are located behind ICs.
The problem with the unit is convergence.Remove convergence output board then replace IC2701 and IC2702 both of them are STK-392-120,After replacing ics you have to go into the menu of unit to adjust convergence.Align the red ontop the green then blue ontop the green.
Check pico fuses F9A04 and F9A05 if either one of those picos are open it means the convergence Ics are bad along with the picos. Your set uses two STK392-570 ICs and the two picos are both 5amp picos. You can get replacement parts and installation instructions at the following link. http://servicemanuals.vstore.ca/
The pico fuses are located on the second board from the right heres a pic of where they are.
the green is half controlled by half of each of the convergence Ics meaning green horizontal is controled along with the red and green vertcal is controlled along with the blue Ics. So if you have replaced both Convergencs ICs the problem is most likely a resistor that is in the green circuit. You will need a schematic to locate which resistors are in the green vertical and horizontal convergence circuit
