Convergence problem philips rear projection tv.

Hi, I am having trouble with my philips rear projection tv. The convergence is off. I havent been able to adjust the red convergence in the menu. i have checked all the resistors and replaced the two ic's with the correct part. Ive also checked all my solder joints and resoldered. I have no solder bridges. I have been reading about checking the pico fuses. Ive checked what i thought were the pico fuses but im not sure if they were the right ones. Does anyone know where they would be on my board or what they look like? Also anyone know of anything else it could be. Thanks so much. Any help is appreciated!

All convergence circuits require two voltages which are equal, one being positive the other negative. Check the power supply for these two voltages and then see if you're getting them at the output ICs. I suspect one of them is missing or low. If there are no cooked resistors near the ICs, inspect the fuses that protect those two voltage sources or the regulating devices themselves.

We no longer have the remote for model 55pp9401 and we have a convergence problem what can we do


Here's the Philips support URL for your TV:

Here's what Philips FAQ says about your convergence procedure:
Question How do I adjust convergence (align colors)? Answer Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

Press the INTELLISENSE button on the remote (under the flap). During the convergence process DO NOT press the INTELLISENSE button again and DO NOT move the Projection TV.

So, I think you're going to need to order a replacement remote.
