Pioneer stuck in stand by

I have a Pioneer SD P4681K. It is stuck in stand by mode and will not switch off of it. This happened after the power went out. It acts like it wants to switch over but never does.

Pioneer SD-P55A5 shut off during use and wont advance past standby mode


This is a problem related to the hue controlls in the TV. It is quite common.

Fix: You can go into the TV settings and try adjusting the hue/tint there.

If adjusting settings does not work, request help from a technician to fix it for you since it will take adjusting the hue internally and if you do not do it correctly it can damage your television.

I hope this helps ya!

Pioneer projection blurry picture


Sounds like you lost the converigence. Have you tried to realign the convergence through the user menu? Try that first and see what happens.

Power cuts off Pioneer SD-P50A5-K about 9 years old


Probably started as a bad solder connection but if it's blowing fuse FU106 now, you're probably in for a new set as that usually means your convergence IC's are bad along with a pair of darlington transistors that's mounted to the heatsink nearby. With the age of the set it may not be worth the trouble. If no fuses are blowing, you could still have a bad solder connection near the Switched Mode Power supply transformer. If that isn't it, you could have a bad High Voltage Block and you may end up having to replace the deflection board as well thank you Pioneer.

This fault happens with just about any tube type projection set. The convergence IC's simply need to be replaced. They are two black, 2"X3", stand up ICs that will start with the letters STK on the surface of them and are mounted up against a large metal heatsink. If you have the soldering skills this should not be so hard for you to do, but please if you do not have the skills or experience to replace these IC's call in a pro to assist you with this repair. Good Luck
