TV: RCA Home Theater Premiere Mod: P52930BL Ser: 826351167 Chassis: PTK195EB June 1998 Service: P52930BL-YX1
Problem: TV has no sound and/or has static when watching just the TV, but watching a DVD, sound is perfect. Apparently, there was some sort of recall on this tv which fixed this re-occuring problem, but it seems to be doing it again. The tv is obviously out of warranty now, is this problem minor and worth fixing?

Re: RCA Home Theater Premiere
When the unit is unplugged and replugged, it empties these registers of the corrupt data. fix is to place a 1mfd capacitor to ground on U13101 pin (15). This swamps the closed caption data to the micro and stops the reception of the defective data packet. In the event that later on the resolve the defective data problem the capacitor can be removed. the close caption feature will not work with this cap. installed or have it fixed click here

RCA always has the part number stamped on the board. It will be a six digit number and usually is preceeded by "P/N". I have worked on these units and would guess that many of the boards are the same. Check the part numbers and if they are the same and the physical layout of the board looks the same the boards should be interchangable. I could not determine through research if the parts are the same because the units are older. I did determine that the CRTs are identical which would mean that more than likely the control signal board for them will also work.
Here are some numbers to call for Flyback Replacement

ThankYou for using FixYa. Have a Nice Day.
You can adj. from the front panel of the set using the channel and vol. buttons,if the set you have has a ptk 195 chassis,check and make sure you have adj. projection tv in screens of the menu,in not the convergence power supply has failed,replace the reg on the board,part number is 215530
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.
Dir TV projection Techcions, I own RCA Model:P52937 Chassis No.PTK195M26B. After a big flood here in Chicago, my basement got flooded and my projection TV was in water up to 1 foot. Befor I turned it on, I dreid it out perfectly, then, I turned it on, and a couple components from the power supply got burned up to the point where I am not able to read the part numbers that are on it. I was wondering if you have this kind of chassis and model service manual for this projection TV, or conponet part number i location 101 on mother boatd power supply. Thank you in advance, Darius

You have already diagnosed the tuner as the problem,the first thing to check is the conections at the tuner specially the ground conections,the shell of the tuner is the ground and it conects to the chassis by being solder to it,if all conections check ok look for overheated areas.After that is taken care you still have the possibility of having a bad tuner.If you are familiar with tv service this information will help but if you are not too familiar be safe and call for assistance from a servicer.
