G'Day,
You will find that the Flyback assembly or the EHT cap connected to the top of you picture tube is "leaking". The hissing sound is arcing caused by insulation breakdown in the plastic block of the flyback assembly, a faulty tuning capacitor in the horizontal output stages, or if you live in a humid climate, dust that may have accumulated on the back of the tube/high tension stages , will create a track of conductivity when it takes on moisture from the air. The hissing sound is the air being ionised by the high voltages present.
There is in excess of 25,000 volts in these areas, and repairs to your set should be done by a professional with good experience if you are not familiar with the problem I am speaking of, particularly about the rubber cap connected to the tube. Voltages remain present here even after the set has been turned off, and will remain so for an extended period. The picture tube needs to be discharged correctly before any attempts to repair problems here are made.
I am happy to discuss things further if you wish.
regards robotek

This hissing sound might be comming from your high limit transformer, Spomething you might want to check in the shop for as its a sign of a breakdown and you want to knab it before it becomes more parts and $$ out your pocket.

I am sure this can be repaired but I do not know how you feel about having it repaired it might not be worth the $$ but then again people cheerish there old tech.

Thanks hope this helps please do consider leaving a rating.

SOURCE: Lost Power

The power supply may have failed. Very often when there are failures in these sets it is from one of the scan amplfiers, and then it takes the power supply down with it.

Your set can be serviced by an experienced tech who especialy knows details about your model type.

32" Samsung TV, No Power or Sound, power LED on, flashes 3 times


Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

PS32500 32" TV Problem


The sound that you hear is coming from the sound detector not working or not receiving any audio. If the set is set to a second audio (SAP) program this could be you trouble. Some programs are broadcast this way. (such as Spanish for Spanish speaking people. Check you audio program settings.

Buzzing sound


You haven't specified where the buzzing sound is coming from, if it is coming from speakers, changing capacitors in the audio section will fix the problem, especially the filters. Now if it sounds like a hissing sound from back of the tv, the CRT base socket is the culprit. It is an easy thing to fix, and the base is cheap, but make sure you purchase the exact same type of base or it will harm the CRT. Good luck.

It's probably the audio amp Ic, which in that unit is a LA7612n...
Replace that and esr the caps locally and you should be good as new.. Otherwise the hissing will eventually be heard on all channels...
