What parts were replaced? Can you hear the high pitched whine when the tubes come on. If not, whoever did the work may have knocked one of the high voltage coils off.

Panasonic projection tv pt-53wx52c no picture red light flashing 3 times have sound


Hi,
3 times red light flashing is an error code that indicates problem in convergence output section, please check and replace convergence output chips and pico fuse nearby. Chips replacement in circuit board requires soldering work and local tv repair shop will help you if you are not familiar with soldering.
Hope this will help.
Thanks.
