Re: no picture

This set is famous for this. It could be the main power supply has a short in it but most likely the Horizontal output transistor is bad because of a bad flyback transformer. Not really a job for a novice to attempt as there is alot of High Voltage present on the picture tube. Good Luck

I have a samsung neo 32 inch picture tube tv. When I turn it on there is no picture or sound, but there is a light high pitched noise.

That high pitched sound is likely the Horizontal Output section trying to work. It operates at 15,750 Hz or at the upper end of normal human ears.
It will sound like a high pitched whine.

This is a section or your television that you don't want to fool with unless you are quite familiar with servicing your set. There are very high voltages involved and only a qualified technician should tend to this defect. It maybe easy to fix or it may be quite involved. Get an estimate first then decide to go further or not. There is a potential fire hazard here so don't operate your set until this is resolved.

The picture is taking longer and longer to come on. It's not a consistent length, last night had it on several hours, it was off for an hour and a half, turned it back on and it took over 90 seconds for...

if you can get another one for a reasonable i would certainly consider that. the cost to get these lcd's fixed sometimes is not worth it. you seem to have more than one problem with the set.

RCA F32650 production May 2003. Was working fine. Turned it on the next day, got no picture and a high pitched whining noise.  Please let me know what I should do to fix it.

If it weren't for the high pitch whining noise. I would say it probably is an internal fuse inside the chasis. It is rated at 1.5 to 2.0 amps. With the whining noise it sounds like a trouble shooting bench
job. Problems occur when a electrical/electronics device is turned on and turned off. Inrush voltage,
when it is turned on, can go up to three times more than normal. This also happens at turn off. Solid state components usually fail at this time. I don't feel that this is a problem that can be fixed in the home.---BBB

Sony Trinitron KV-19TS20 Screen displays purple static or awful image.

This unit needs a tuner. A new one from Sony will run over $70, so I doubt that it is worth it. It is possible that poor ground connections could cause something like this, but the symptoms seem a bit too severe. I think it is time to invest in a newer set.

Samsung SlimFit 30" high pitch whining noise

I have had the same high pitch tone problem for several months after about 20 minutes of use. It is so bad it's rendered the TV almost unwatchable. I contacted a repair place from Samsung's website. I was told that is likely the flyback transformer. I don't know what it is, but it sounds cool like a flux capacitator. I was told it would be about $100 to fix. However, I have had very little luck getting the repair shop to order the part and do the work.

High pitched whine when the motor starts

Had the same problem. It quit within about 5 seconds after turning the TV off. Replaced the color wheel and the whine is gone. The picture also looks brighter, which may be due to dusting the projection lens with lens-cleaning compressed air (from a can). The color wheel was about $100 from Samsung parts and it took less than 3 hours to replace. See for good info, and be sure to read the cautions.

Hi,possibly the line output transister has gone short,proberbly caused by a dry joint,or worst case it is the line out put transformer itself and that could be a bit pricey to replace.

Will not power up

your problem is in flyback or high voltage section failure.

  • check horizontal output transistor
  • check fly back transformer.
  • check for supply to horizontal section as high voltage from power supply may create such problem
  • as this failure is due high voltage section so it is better to take skilled technician help.
  • good luck.
