When the TV is on for about 10 minutes (warmed up), it recently started making a loud popping and cracking sound. The picture also blinks in a pixelized manner. What needs to be done? How can I fix this.? Thanks, Jack DeHaven

Re: rca p52151WK projection tv problem
It is not worth to fix,even if you could do it. With the replacement part cost,you might as well buy a new TV.With the economy today,and Circuit City is filing Chapter 11,and best buy is hurting,you could get a knock out deal from a retail store! Solutiondoct

No , if fuse was blown you would not get the popping. How old is unit ? It sounds like your high volt splitter. common problem with rca. repair should not cost more than 250.00. you will want to have chassis number and manu date for help
that would be the inverter board, supplies power to the bulb, you would need to replace this part, but don't touch the board without wearing rubber gloves, as it can store a lot of voltage when they fail . when you get the board out discharge the capacitors to make it safe. cross the live and negative on the capacitors.
It needs a new FLY BACK transformer. That is what you are looking at. The origionals are not made for the set any longer but insist on having a generic on installed by a local TV shop. I just put one into a RCA 31" and it works nice. Don't throw away the TV. Get it fixed. MAKE SURE YOU INSIST THEY USE THE GENERIC ONE! THEY DO WORK!
Is the audio coming from the TV's internal speakers, or from an external sound system? In the 169 series chassis, if the power supply caps or secondary rectifier are bad, or if the high voltage splitter has shorted inside, the set will not run and there will be no picture or sound from the TV. If the picture is completely black but the TV still has audio, press the menu button and see if the menu comes up on the screen. If the menu is there, check your cables on the back of the TV. If you are using a cable or satellite box, the box could be bad or the video wire could be bad or loose. If you do not get the on-screen menu, then I would guess that the solder joint next to the flyback transformer that sends filament (heater) voltage up to the picture tubes has cracked, or the low value resistor in the heater circuit has opened up. If that is the case, have the set serviced by a qualified tech familiar with the 169 series chassis.
