I have a 32" GE regular crt TV. Everything was fine and when I woke up the next day it would not turn on. Keeps making a clicking sound every few seconds like a solenoid trying to close..

Sounds like a probable shorted Horizontal Output Transistor (hot) Hopefully thats all. Sometimes the flyback will fail as well. If your not familiar with electronics I would recommend a tv shop repair. If its just the HOT transistor average repairs are 75-110 depending on your location.

No pix/sound, just high pitched whistle

Ur tv the high voltage it dead,the FBT,the flyback transformer.The big black block of plastic with a red wire with a black cap that hook up to the CRT(tv tube) is dead.The FBT,flyback transformer needed it to be replaced to solved this problems.Call the shops,take estimates for the best deal to do the repair.This is one of the main part of the tv to put HV in CRT(tube tv).It pretty hard to find this FBT these day,because of the discontinue of making of Amalog tvs.

Picture is blurred were i am seeing multiple images in odd bright colors. when tv is on without cable box, there are a couple red and green lines across the top third of the screen

Your TV has a Convergence submenu. Verify that this menu is still present (use your user manual to locate it in the menu). If it is not there, you have a solder quality problem on your HV/Deflection board and a fuse has opened as a result. It will need to be repaired. I suggest NOT using the TV until this is fixed, as further damage can result.

If you are a DiY person: remove the HV board (left side with red anode coming from FBT), clean solder from the FBT connections, reflow the connections (make them look wet and shiny), check the fuses to the right of the FBT (there are 3, they look like little rust colored boxes), replace as needed. These fuses can be hard to get, the culprit is >500mA if memory serves me. Also, give a good inspection on the rest of the board for broken solder joints and repair as needed.

Focus wire from flyback transformer lost position?

Yes, yoke plug in should be next to or behind FBT.

Won't turn on

Although the other response is in much better technical lingo, it sounds to me like the television had a high voltage arc which I have seen on quite a few of the sony big screens lately. Usually, it causes a part on the circuit board, (one of many that were listed on prev. solver's list) to fail. This causes a delimma for the repairman, because when they find the bad part and replace it, sometimes it will pop again causing repeat failure of boards and/or parts on the board. Sony is known for having bad tubes on their projection sets, and it can be a difficult repair even for a trained tech. I suggest calling a sony service center in your area, and get an accurate estimate before deciding if replacing the set is the best idea. Hope this is helpful input, Russmann.

RCA D52W19 Flyback Transformer

This transformer does not come with the hv lead,if the arch is coming from the side of the transformer,cut the side of the plug were it goes into the transformer and the lead will come out,there is no voltage stored on the hv lead after the set is unpluged for a few min.,the transformer you can get at any rca repair center.
