The relay just after the input transformer is buzzing loadly (oscillating) when the power button is pushed. The TV video and audio is fine. The bussing is not coming throught the speakers. The 6W resistor between the transformer and relay is also getting very hot with just the set plugged in but not turned on. Does anyone have a solution? Thanks....

I had a problem like that so I disabled the tv's onboard tuner (input source)and now we use the cablebox's video and audio out to the video and video in jacks on the TV this will work as long as you have a cable box or sat reciever for your video and audio source and of course your TV must have video and audio inputs so it will work.
My Loewe Aconda 81 HDR TV will not turn on. When I press the power button the green light comes on but the red light stays on with it and after a few seconds the green light goes out and the red light stays on. Any help please.
Initially, if you have confirmed that the source of the buzzing sound is from inside the TV, then that would indicate a component about to fail or would need attention. Let us try process of elimination:
tuner - most unlikely, the tuner is responsible for selecting the channel. No component/part of the tuner could make such a mechanical buzzing sound;
speaker(s) - most unlikely, the speaker could have a buzz but generally would not affect the video nor cause snow (weak TV signals);
transformer - a strong possibility although without knowing the exact model, at most generic ideas; power transformer, flyback transformer, horizontal drive transformer (unlikely);
arcing - another strong possibility. This could be caused by damp, dusty surroundings of the components especially at the FBT area. Another area that could have adverse effect when dusty/damp would be the anode cap.
This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
I had the same problem with the same model. The solution was to replace a capacitor, C622, which is located near a small blue rectangular plastic component. This component is a relay that is controlled by C622. I paid $2.39 for the part, $8.99 for S&H for a total of $11.38. This fixed my problem!
I will guess you remember tube sets from our parents days !
They stopped being Mfr'd in 1972 !
Best solution for your set = replace horiz transformer and
transistor with RCA part # 's 257807 & 237470................T.
The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit.
I've repaired several RCA's with this very same problem.
The newer RCA's are vert prone to high voltage transformer failure !
Hello to all you buzzers, I have the answer to your problem. First this is what's happening. The buzzing is coming from the power relay. It vibrates at 60hz because the power supply filter capacitor is not doing its job hence you have a rough d.c. pulse going to the relay.To solve the problem remove back of t.v. slide circuit board out (you will have to disconnect white wire from degauss coil,located on left front) look for a blue box approximately 3/4"x1 1/2" this will be the power relay. Now look for capacitor location #c622 near the relay. This capacitor should be 470uf 25v. Remove and replace with 470uf 35v capacitor, connect white degauss wire temperarily put back on and give it a spin. Hope this solves all the buzzin,robert
