Question about Toshiba CF36G40 36" TV

Cable connection generating static on screen & noise

The problem started with noise and static on the screen only when the TV was cold and first turned on, which faded after the TV warmed up. Slowly the static continued longer & longer. I was able to help or worsen the problem by pulling on the Cable TV input cable. I then grabbed the input connector on the TV where the Cable TV cable connects, and was able to again generate the static / noise with small movement of the connector. The Cable signal to all other TV's is good. How can I fix the issue?

Re: cable connection generating static on screen & noise

Your problem is probably the tuner in the back of your tv. I had the same problem. I ordered a new tuner. The model number for it is  CF36G40

Re: cable connection generating static on screen & noise

Hi, it sounds like ya most probably gonna haveta resolder the Cable Connection Socket internally.. they often fracture, OR perhaps it is the Actual Cable Connection Plug itself?.. maybe you need to remake this input connection? Indeed it sounds as if the Earth Shielding is making bad contact...

Static noise and blurry screen

You need to take your TV set to Service Center, because the inner parts, especially the flyback transformer, been damaged or worse, the connector broken, that's why you can hear the noise.

Suddenly no sound & no picture overnight: is my TV dead?

If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.

Appreciate the direct "Ask Me".

Technically, when a TV signal is said to be snowy, it indicates that the incoming RF signal is weak; on the other hand, when a TV signal has static, this refers to electrical noise that goes with the TV signal.

Having said that, then to your concern:
  • for snowy signal, it is the cable providers problem. They have to change where your incoming cable is tapped from, check/replace the feedin cable itself or worst case scenario, replace the line amp/distribution amplifier feeding your cable input;
  • for static noise, what is required is to check possible sources which could include (but not be limited to) electronic ballasts of florescent lamps, electric fans, hair dryers, shavers, wireless phones, computers and others.
Additionally, you may want to check if you have any RF producing devices attached to the TV such as VCRs, DVDs, game consoles. You can try unplugging them when not in use.

Worst case scenario is the tuner block of the TV is getting weak (unlikely but possibly). You can try rewiring the cable to feed first into a VCR, connect the VCR to any of the free Video IN, and select channels through the VCR. If significant improvement, then you have just confirmed an internal fault with the TV tuner, if problem persists, then the static/noise/low RF is caused by something else.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Audio has a lot of static

You can possibly diagnose the problem by trying a different speaker,it does not have to be the same shape as the original but it has to have the same amount of resistance (ohms),radio shack might have one that you can try or one from a broken radio ,if you use one with different value it might not sound as loud but we are trying to see if you hear the static or is gone.You need to unplug the unit from the wall,remove the back cover and locate the speaker,disconect the wires and reconect the one to try then plug the set and turn it on,the antenna will need to be reconected too.Is the most simple test you can do without getting in too deep.Let Us know how it goes by a way of a new question or if you need more information.
