This is another typical issue with power supply boards. You need to have a qualified tech look at this and determine which board is bad, but it points to the power supply, they get the hottest and burn out the earliest.

Just turned tv on when it made a pop sound, the picture goes out, then started clicking like an electric arc jumping sound. Now when I try to turn it on- no picture and all I get is this clicking/arc jump....


This is the starter relay, the powpping sound was the death of a number of capacitors on the power board and possibly on the sustain boards that control picture and sound. This is major surgery, not just a board swap job.

Cost of repair estimated is about $600.;00 for parts and labour If there is any extended warranty use it now.

Will not come on it only a clicking sound from part no. 0mron 0584H3


I had the same problem with my tv, same make and model. I first continuously turn on and off my tv manually until I could get some kind of picture. This procedure took maybe five minutes. I was able to get a fine picture and sound, as if it was brand new! Other things to keep in mind, try to eliminate dust build up as much as possible.. Hope this helps out...

No sound or picture


your relay is turning off most likelt due to on of the stanby voltages being out of parameters I would check the low voltage regulators and the horizontal output transistors.

No picture and clicking sound only


This may be a power supply problem or a shorted horizontal output transistor shorted. The clicking sound is the power supply trying to start but can't because of the overload. Stargazer

No picture or sound


If you had a burning smell, well the board is toast. These sets are made to replace the entire board at one time. Before installing the replacement module, the picture tube should be checked. A defective picture tube ( such as a G1 short) may cause a failure in the power supply section.
