Question about Panasonic CT-32SL14 32" TV

1 Answer

Whistling problem hi.. how are you?..im carl, nice to meet you..i have a 32" panasonic tv purchased within the last 5-10 years..when the screen goes primarily white or bright, a high pitch whistle(much like an audible dog whistle) comes from the tv..i dont think it is coming from the speakers..the only reason im reaching out to you is you had replied to a request asking if the noise only occurs when the screen goes bright..so, it sounded exactly like what i have going on..any help you could offer would be incredibly appreciated..thank you very much carl gdofthndr88@yahoo.com

    I have the same problem. Does anyone have a solution?

    hi,

    I will be glad to help you , you will just have to determine what part the sound is comming from , and this part could be an IC , coil or the tube. so you will need to open up the set , hook up the antenna or cable and listen for the area that it is comming from , then let me know if you can pinpoint the culprit. we may also need to do some testing when the suspected part is determined, to check to make sure another part is not causing the breakdown

    I'll analyze your results after you post them and let you know what you will hae to do next

What you can hear is a coil on the main line timebase board resonating at half line frequency, about 7.5k and 15.625kHZ or whatever the line frequency is in your country. Nail varnish on the coil will usually cure this.

SOURCE: TV screen wont turn on but just a loud noise coming from the tv

I think maybe the G-board needs to be replaced. A TV shop will have to repair it. They normally start around $200.00

I NEED A NEW SCREEN WHERE CAN I FIND ONE


Generally, a 32 inch TV costs more to repair than the TV was worth. If you've purchased it within the last year and you're covered by warranty, they may replace your tv. Otherwise you're better off shopping for a new one.

At the local big box electronic store, this TV is already out of stock as it is obsolete. The new models will be out in a few weeks.

Hi,
I replied your previous question, click HERE to read it again.
If tv shows bright picture in proper focus then it would last few more years as it is rear projection tv that has 3 picture tubes (red-green-blue) to project color picture on front screen.
Its your choice to have new tv instead of repairing this one and yes, its correct that 32 inch tv is available under 700-800 dollars.
Hope these info will help you.
Thanks.

Apologies to Andy Hi Fi and tvtek who both answered this query yesterday, but I gave out the wrong model of tv. My set takes about 5 minutes to produce a picture, which is then as good as ever. Sound comes...


This fault sounds very much like the CRT (Cathode Ray Tube) is approaching the end of its life. If you can find a TV engineer in your area - preferably one from "the old school" - he may well have a "Tube booster". This sometimes works to "rejuvenate" old CRT's but can also unfortunately, bring an abrupt end to the tube, because it involves passing a higher than normal current through the tube heaters.

Environmentally, it all depends on the age of your current TV and the size of the screen. If it's a fairly large screen, (32") it will probably consume around 250 to 300 Watts of electricity. Modern LCD TV's are more efficient, however gas plasma TV's tend to use slightly more power than LCD models.
As you will know, TV's don't use that much power in comparison to say, a cooker, electric kettle, fan heater or washing machine heater so you can expect to use around 200Watts for your new TV if it has a 32" screen. Power consumption goes up of course, the larger the screen size you have, so if you bought a 40" or 50" screen you would not save anything in power compared with your old CRT type TV.

If your current TV has lasted for 20 years or more then you have done reasonably well. That's not to say that many TV's with conventional CRT's often last MUCH longer than this.
Tandberg CRT TV's have been known to still be working perfectly well after more than 30 years! Much the same with Panasonic.

What is the gas/oil mix for a mccullock 120? Thank you Carl


Fuel/Oil Mixture
  1. Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 8oz/2gal - used for many years) and finally the last 5 (±) years 50:1 (Stihl 2.6oz/1gal)
  2. Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few months. Anything over 6 months old use up in a 4 cycle engine. HTH

Screen is fine when I first turn on TV, then goes black


Sounds like you dlp lamp is going out. That's a pretty old TV and if you are still running on the stock lamp this is exactly the type of thing that will happen. The lamp model for this particular tv is the ty-la1001. You can find that over here:
