This is caused by either carbon arcing from carbonated food deposits or metal dish or bowl being used inside the machine causing a track. Even a recycled paper towel can cause it as the towels have metal traces in them.

A shorting noise is coming from inside the tv box - this happens when i switch on the tv but later , after 5 minutes or so stops - the noise , in bursts, asif two wires are touching.


Hello
There is a high tension arcing takes place inside your tv. It may be related to Line Output Transformer [LOT], and neighbouring parts. You can locate this by placing the tv in an absolute dark room, switch it on, and notice its inside through the back ventillations. you may see bluish arcing takes place, and an ozone smell will come too. Never switch on the tv till this fult is retified. Some other parts alo may get damaged.
Contact a sevice personal and get it repaired as soon as possible.

Runs like ****, backfires and chugs, no power


Several possibles: Plug wires arcing (run engine in a very dark area and open hood to see is there is arcing) Bad coil (same test look for arcing sometimes you can hear spark jumping) Distributor cap arcing inside or outside ( remove cap and inspect for carbon tracks inside cap). Module inside distributor bad (not too expensive to replace). Lean toward wires or coil.

Tv went off and won't come back on.


the arcing sound is some kind of high voltage leak, which will shut down the tv. pull the speaker grill off and the access board, look at the 3 picture tubes, turn the set on you will see where the leak is, it's usually the high voltage splitter, which has a high voltage wire going into it and 3 high voltage wires coming out going to the picture tubes, if it arcs from the splitter you need to change it, if it arcs from one of the picture tube wires you need to pull the tube out and fix the high voltage leak, and possibly a cooling fluid leak caused it, not an easy reapir, you probably need a repairman.

Arcing inside no picture


Most times arcing like this is from the Horiz. output transformer (flyback). The insulation has a break down and up to 30 KV will find the nearest path to ground. This would require a tech. to repair the unit. This repair will most likely cost around 250.00.
