Hi, thank you for visit fixya.
Do you have a problem with power supply parts.
CTC169 chassis series is a common problem , we have a power supply kit for this set , iclude capacitors,IC ,diode and transistor).
CR4118 need be replace too.
If you need aditional information, please let me know.
I have looked through most of the answers to the same problem question and found my answer. I thank you very much for your site for the free info as the cost could have been huge to fix it. Now that I no the part the cost is minimal, and I can do it myself(with a little help from my friends).
Again Thank You
The most common problem with these Models/ Chassis' is IHVT (intergrated high voltage transformer) going bad. They have around 99% failure rate. T14401 > part number > 239111 >IHVT.
Try to get RCA part a little more pricey but more reliable then after market ones. You can tell if it's bad by the crust on the top of IHVT.
Good Luck, big IRISH.
The P52940 uses the CTC195 series main chassis. The most common reason for the set not to start up is a shorted flyback (high voltage) transformer. The set actually does try to start, but the computer immediately detects the extra current drawn by the shorted flyback and instantly shuts the set back off. The chassis should be checked and the flyback replaced by a qualified tech familiar with RCA projection TV's.
