Question about Panasonic CT-27G34 27" TV

Panasonic CT-27G34A screen jiggles/glitches up and down slightly

My Panasonic CT-27G34A standard definition 27" TV (1999) just recently started having a problem: the screen will jiggle/glitch up-and-down just slightly (maybe 1-3 scan lines in height) at random intervals and durations. I've verified that it is independent of which TV input I am using (ie. across 2 sets of RCA inputs, 1 coax input). It will do this jiggle/glitch at least once every 5-10 minutes, and will last for anywhere from a few seconds to a minute. But then it will stop doing this for many minutes. I also intentionally jiggled the various input cables lightly at the connection into the TV and confirmed that this does *not* cause the problem, so it's not a bad cable or TV connector. My best guess is something is wrong with the actual CRT scanning gun or electronics.

Any idea what is causing this? Is this something I can fix myself (I'm pretty handy with a soldering iron), or something a TV repair shop could fix?

You will need a degausser. Check out Wikipedia for the definition. Look on ebay or your local TV repair shop. Cost should be $20-$100.

Buzzing sound, no picture on my Panasonic TV


You might have a short causing the set not to start. Probably in the horizontal/high voltage circuit. The buzzing sound that you're hearing is the power supply overloaded. Stargazer
