Question about Toshiba CF27F50 TV

1 Answer

Crackling and lines for about 5 minutes then is fine

When I first turn it on I get a loud cracling thar doesn't change with volume control. Some lines across the screen. It comes on fone after about 5 minutes. Now before that I get snow before the crackling but again it's fine after about 5 minutes. It's not a cable issue. I have unplugged it for a minute or two to try to reset. That did nothing.

Could be a bad solder connection at or near the flyback area. The flyback delivers high voltage to the tube.

Sub Speaker giving intermittent loud crackling and sharp loud popping sounds even with main volume control turned off. Crackling sound can be reduced by turning sub volume control off.


It may be the control itself too. In time, these controls can get dust build up inside it. There are volume control spray cleaners available from Radio Shack or other electronic parts stores. The cheat on cleaning the control is to just rotate it from stop to stop as many times as it takes to clear the noise.

It sounds like you've done quite a bit of troubleshooting, which I applaud you for doing. Have you tried power cycling the TV? Simply turn off the TV, unplug it (and any components connected to it), then plug it back in and turn it on after a minute. See if this corrects the issue. If it doesn't, then I would recommend calling our Product Support team to schedule repairs at:
U.S., Canada, & Puerto Rico - 1-800-305-2204
Mexico - 1-888-882-7326
daily from 7 am - 12 am CT.

I have a yaesu ft-736r with no audio


Hi Jermaine,

It transmits, but no receive, are you sure, have you tried playing around with the volume control?

If, so did that make any crackling noise? If so, then this is due to lack of use of the volume control, many radios, including the old transistors with dials, would make crackling sounds when you adjusted the volume, and as I say, this is due to lack of use, So if this is the case and to get your receiving, turn the volume control up & down fully for a few minutes and while doing so your radio might receive a transmission that will be loud, quiet, loud, quiet, etc., as you play with the knob.

Keep doing so until all crackling has disapeared.

Do this often as possible when firing up your radio for the day, the more use these controls get, the better.

I hope this has answered your query.

Cheers,
Peter

LG LK53-TV cracling noise


One, it has to be under warranty if 2 months old....

What you may be doing is just driving the speakers (a lot of sets have tiny ones now) too hard with the bass set up===literally rattle them in their frames----if the set has a connection on rear for external speakers that might be a option.

Some of these sets (check the specs) have a very small audio output circuit under 5 watts and with volume up and bass up sound will be hard in deep bass situations....

My Korg c15s has a lot of grating staticky noises when played ....I'm told it cannot be repaired as Korg no longer makes parts for this model?


I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.

My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.

I hope this info helps a bit.

Very loud hummimg and crackling - even when volume turned down.


There are a few variants for this model depending upon the serial number. From your description, there are some capacitors in between the amp stages called coupling caps that are failing. The hum is some DC current being passed through the output stage. The crackling is probably just dirty controls.
