Question about Televison & Video

1 Answer

Panasonic CT32D-11 turns itself off after a few minutes on; on periods getting shorter and off periods getting longer. Sometimes an arcing sound is audible, with some hash visible in the middle of the screen during that noise.

    Thanks! With the arcing sound, I suspected a transformer of some kind. I'll try to find a Panasonic repair faciliity in my area.

This is a classic switchmode power supply, the Protection Circuitry has sensed a severe potential problem, and is shutting down to avoid a fire, explosion, or both. The "Fault" is sensed, the set shuts down, the "Fault" clears, the PSU starts up detects the fault, shuts down, and so on, this will keep on, until the faulty components finally do fail completely, often with catastrophic results. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center, Panasonic, in your case, now, this point is very important for a good result, Always contact, "their" local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done

Sounds like it needs a battery.
After a few years those batteries will charge up to the correct voltage, but the length of time that charge lasts gets shorter and shorter, You probably have a drill, a razor, a laptop computer, or a flashlight that do not hold a charge as long as they used to, I know that you have a camera that doesn't hold a charge .
Sounds like a battery problem,

Sony kv35s66: No picture, just sound and red blinking


This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.

Keep us posted.

My rca 52 inch hdtv turns itself off after a few minutes


Sounds like the green tube shorting intermittantly. Have a qualified tech use a tube restorer to check for shorts, or the loss of the 300v line to the green tube.
