Question about Panasonic TX-28DK2 TV

1 Answer

Repetitive dull thumping noise

The picture is fine and the sound is fine apart from a dull pulsing sound every second or so which is very irritating. The sound is coming out of the speakers as distinct from a clicking noise from the back of the TV. Any thoughts?

    I also have a dull 'pulsing' noise coming from my rear speakers, but when I played around with the center speaker, I could sometimes get good sound coming from it when attached to the rear wires. It happens when I activate surround sound whether I'm watching a DVD, or using my xbox 360.

You're in the UK, right? Try unplugging the set from the mains and let it sit for ten to fifteen minutes. Are your speakers built in or detached? How long has this been happening? Have there been any changes recently that coinside with the problem? Are there any other audio/video devices connected to the set? If you have other devices, does the problem exist when they're in use? The clicking noise sounds like a relay that's searching for another device or input. Check the audio settings on the menu to see if something has changed. Hope this helps.

Makes a thumping noise


Most likely your needle needs replaced. As they get older, or hit a pin, they will dull. You can usually tell by your stitch quality, or the thumping sound you are hearing.

Front suspension noise-dull rattle-thumping sound,bumpy roads


look at the front lower engine mount. I had similar noise which has been driving me nuts, thought may be thesway bar links, put it on friends hoist and saw that the front engine mount (mounted to bottom of lower radiator support) was cracked and the rubber bushing inside very worn with pieces missing. odd thing is that reving, or putting into gear never caused it to make a noise, just certain bumps. I ordered part from Autozone,hopefully it gets here before the holiday week end is over.
Good luck

Microwave making dull thumping noise when NOT in use


I called a technician out today. Seems like the problem is the circuit board. It wasn't working properly and the sound is the fan. The fan is supposed to turn on when the microwave is in use and off when it is not. In this case, the fan continued even when the microwave was not in operation. A new circuit board has been ordered and will replace the old one when it arrives. For now, I can still use the microwave, but I have to unplug it everytime I finish heating something up. A little inconvenient, but at least it'll still heat my food up in the meantime.

Bass speaker start up noise


Hello anne845,

It sounds like the installer wired the amp remote turn-on terminal to an "accessory" lead in your vehicle. Many stock radios do not have a dedicated amp turn-or lead and the alternative is to connect the amp to a switched power source (ignition or accessory). This means the amp turns on whenever you turn on the vehicle ignition, often resulting in a thumping from the subs. It is a perfectly satisfactory alternative, and will not damage either the amp or the sub. But it's irritating.

If the thumping is objectionable, have your installer wire a SPST (Single Pole, Single Throw) toggle switch inline with the turn-on wire. The switch should be mounted so it is accessible by the driver, and whenever you turn on the radio, turn on the toggle switch.

Hope this helps.

No picture and thumping sound


I just had the same problem with my TV and looking on the web I found a site that helped. The site was www.freelists.org/archives/techassist/11-24/msg00326.html The entry said Raster NO GO / Pulsing sound from speakers / Poss ant relay clicks in time to the pulsing. It recommended replacing C816 and C5a28 (100uf /200v Caps) C5a03 (4.7uf / 200v cap) My set did not have the ant relay clicks and I could not fine the C816 cap on the circuit board and I didn't have the schematic. I found the C5a28 and C5a03 caps about the middle of the circuit board in the same circuit (around the metal L shaped bracket). The C5a28 cap was bad and the C5a03 cap was fine. I replaced the C5a28 cap and the set works fine now.
