Hi there, i have an old Philips 43pp925/79 rear projection tv. A few weeks ago convergence ic went bad, so i replaced them both and i replaced 6 resistors. Now there is no bending on the screen but the color is all over the screen. I tried to align them from menu but i can't move red or blue dots. i dont know where i went wrong. it looks like 3D.

    With TV on Press Menu ,While menu is up Press 0-6-1-5-9-6 or 0-6-1-5-9-7 using arrows Left/Right to select up/down to adjust. try these and see if it will let you adjust.

Several years ago we purchased a Philips 60" Rear

It seems problem with convergence output section of tv and convergence output ICs need to be replaced by professional because it requires soldering work with proper tools.
Please call local tv repair shop to get tv repaired.

Can't correct my red blue convergence manually or by using factory preset...the unit is 7 years old, is my picture tube bad?

You have bad convergence ICs. There are 2 ICs in the convergence circuit, one is for the Blue the other is for the Red. You can buy 2 ICs for under $40.00. Replacing these ICs require soldering and desoldering skills. Sometime, the resistors in the convergence circuit go bad also. Be very careful, there is a very high voltage in a CRT projection TV the voltage is over 30,000 volts.
Best of Luck

My hcp4752 started smelling hot now the colors are

It looks like you have a problem on your convergence panel. Look for burned resistors near the STK-* IC's. One or more of the STK-* IC's may be bad. When the resistors get hot they smell but so do the IC's. You can replace the bad parts or you should be able to replace the entire panel then go thru a convergence alignment.

Problem with Colors Seperating

can the remote move the clors in all 4 directions? If not the convergence ICs need to be replaced. Also check the resistors that power the ICs they are located right next to the ICs
