Contact Philips directly. They should be able to get you the part, even if they have to get it from another repair shops. Many repair shops purchase their parts from factory authorized distributors, not from the manufacturer. The flyback transformer powers the tube-it can be extremely dangerous to work on-EVEN with the tv off, they contain a lot of power somethjing like 50,000 to 150,00 volts. It is not fun getting shocked by one of these as many techs have been knocked unconcious by them. If you do not know the proper procedure to discharge a flyback then leave it alone!
You need to resolder the flyback transformer and replace fuse FL221 off pin 11 of the flyback transformer. The convergence power supply is not coming on so system control thinks a convergence circuit is not installed.
A flyback transformer is one of the more expensive components in a projection TV. If there is no clear reason, such as a known power surge, you could well replace the flyback transformer again soon because the root problem was elsewhere.
An OEM transformer is not necessary but you might have trouble convincing an authorized factory service technician to use anything but the original manufacturer's parts.
As with many of today's electronic devices, if it is more than a year or two old, you will find the new products cheaper and with more features.
The next generation of projection TVs will use lasers and scanning will be done with optically controlled micro-mirrors - no flyback transformer required.
DId you solder the flyback transformer connections..... This is the main reason these fuses fail. THe flyback is the big black component next to the fuse. poor solder connection cause oscillations.. this fuse is only .4 amps whish dosent stand up to that well.. resolder these pins on the flyback.... the first time i replaced this fuse i failed to solder played well for 2 days then came back blown again
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.
