My rca HD52w59 is making a very high pitch sound about every 10 seconds. I turned my tv off and back on. When i turned it back on the squeal will last about 10 seconds, it will stop then squeal every 10 seconds. Please help.

Thats the classic sign of a failed deflection board. You can get the ITC222A deflection board which comes with warranty and installation instructions from www.tvrepairworld.com its listed as the ITC222A remanufactured deflection board under the RCA CRT Projection Circuit Board catagory
The FBT,the flyback transformer is dead.Some the transitors in the deflection board is dead also.U know how to used a Ohm meter,and know soldering.Tries wesite like Tv repair World.com will help u to find the cause and replacement parts.
is this just a whine since you describe no problem with the picture it dosent jump or change color or flicker. there may be an easy fix this sounds like some coils oscillating and i tell you what can be done you can take some silcon and put on these coils to dampen then vibrations. now ther may be other problems but without looking this is my first gues ...where are these coils? ll037 on the power supply deflection board
ok does the set show a picture durring this whinning
i have ran into this problems .. sometimes it has to do with a coil that is oscillating...ll037 or ll029...the fix for this is simple if it is the problem. dampen the coil with silicon.
In this model the horizontal drive coil vibrates and makes a high pitch squeal. Most times it is intermitent. Touching on the coil with something (non electrical, like wood) will make it stop or change it's pitch.
The fix my shop uses:
It's not to technical, but, we put fingernail polish around the coil. It's a remedy I've used for decades and has always worked. Some shops use a hot glue gun.
With the back open you can hear the coil to locate it. When fixing the problem have the set unplugged.
When a technician is working on a television while it's plugged in. He uses only one hand and stays away from the high voltage.
