The boards need to be resoldered .the larger leads do not get a proper heat because of their mass and the wave technique used to solder them on the factory does mot give a good connection so what is happening is the TV warms up and expands and then the connections disconnect

awewryte,
I have the same TV and now have the identical problem that you described. Did you ever get it fixed or find out what the problem was? If so, will you please pass the information on?
Thanks.

Rca r52wh74 - no auto convergance


The model number of your TV probably falls under the ITC-222 chassis design. Do a search based on that criteria and it should point you in the right direction. If I remember right, you need to replace FL231 on the deflector board though. Good luck

Where is a the fuse in a rca model r52wh74


On the main power supply board. To get to it you will need to remove the back of the case and locate the power supply board ( follow the power cord to the board ) and it is next to the connector.
BUT, I doubt that is your problem because if the fuse is blown then there would be no lights.

Go to menu then setup look for convergence if it is missing on menu then you have a open FUSE/ FL231, But if you have convergence on menu then go into service mode turnTV off then PRESS and hold at same time ch- and vol- wait for set to come on then release TV should now be in Factory settings.

you need to replace chemical type fuse marked FL231 part number 259213, it`s located next to the flyback transformer, theres 3 of them there but 231 is the only one I`ve seen cause your problem, replace it and you`ll be all set.Happy Holidays !
