I have noticed some arcing noises coming from the TV every couple of minutes. The picture is fine, but the noise is pretty annoying. Any suggestions as to what is causing this or possible solutions?

Clicking, popping noise on certain channels. All connections checked for tightness, and sound is isolated to the TV, not cable box or home theater. What is the cause and fix? Does it involve an inhome service call?

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.

Toshiba 62HM195, Loud hum noise when TV is first turned on.


I have the exact TV and had the exact same problems. It is the light engine with color wheel that needs to be replaced, and they are VERY hard to come by for this model. Our repairman has had our TV for 5 months and still cannot locate a vendor that carries the part. He said according to Toshiba, the part has been discontinued. If you happen to find one, please post. I'll do the same.

High pitched noise from inside the TV when picture comes on


Hello randapaint,

This might be from the IHVT (Integrated High Voltage Transformer), or more specifically a short in the IHVT causing it to arc, producing the high pitched whine, you are hearing. Take the back off of the TV and try to detect where the sound is coming from, more then likely you will notice it coming from the section that contains a large component with a large red cable coming from it, to the top of the CRT (picture tube). Replace the IHVT (with the exact same model) if it is bad.

I hope this helps,

Thank you,

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

Toshiba tv making crackling noises


Is the sound coming from the speakers or from inside the tv, like an electrical arc? It could be the high voltage wire going to the picture tube. Do not attempt to test this yourself as there is many thousands of volts on that wire even when the tv is turned off. That wire attracts dirt that may be causing it to arc.

Panasonic PT-53WX54 What is that popping noise?


A loud popping noise, like a sharp "snap!", is usually caused by high voltage arcing. Somewhere in the high voltage system an insulator may be cracked or loose, such as the plastic around the flyback transformer or one of the rubber cups on a picture tube. When the high voltage arcs, it momentarily drops and the picture could go out for a split second. High voltage is dangerous in projection sets so allow a qualified tech to service it for you.
