Question about Toshiba CN35F95 35" TV

1 Answer

No pic/sound on main screen

My TV is having a problem that I searcherd for but not addressed... My main picture is receiving no signal resulting in no picture or sound. However, when I turn on the PIP, it shows a station with no problem in the PIP box. When I swap, it tunes to a different station in the PIP, but still no picture/sound on the main screen. There is only one cable input and no other devices attached. I tried to reprogram and unplugged the TV for a day, but there was no resolution. Since the PIP is receiving a signal and picture, is there a component that accepts the signal input and then directs it to two separate locations - main & pip? Is it fairly easy to replace? This unit is not easy to transport and the nearest service is about 35 mi. away.. Thanks in advance

Tv 27" has only half screen picture horizional I

Possible failure of the VERTICAL SECTION of the deflection circuit. It is possible that the areas related to the vertical circuit is checked , check for weak capacitors near the output vertical drive. Also a faulty vertical coil- deflection coil- can result in half picture.
A vertical signal test can confirm.

Black screen

Possible causes
  • Your TV is not receiving or displaying the signal from your DIRECTV® Receiver.
  • Your receiver has correct guide information, but is not processing video correctly.
  • You are viewing a channel where an upcoming sporting or special event is scheduled or has recently ended.

  • Turn TV off and on.
  • Make sure light on front panel of receiver is lit.
  • Press the "TV/DSS" button on the remote control or front panel of the receiver (not all receivers have this option).
  • Reset the receiver by unplugging the power cord for 15 seconds.
  • Check all cable connections between the dish, receiver and TV.

If the picture is black, but the program title and description display in a banner the top of the screen:
  • If the problem is only occurring on a few channels, check the detailed description of the program through the on–screen guide on those channels. Often, we display a blank screen with a banner before and after a high–profile event to alert customers about the event.
  • Reset the receiver by turning off and unplugging the power cord for 15 seconds.
  • Run a signal meter test to check your signal strength (press "menu" and look under "setup" or "installation").

If your signal strength is below 70 (or below 60 on HD receivers) in clear weather on transponders 1 and 2, see our troubleshooting steps for "Searching for satellite signal. Please stand by." You may see zero strength on transponders 4, 12, 18, 20, 26 and 28. This is normal in many areas. Your system manual shows how to run cables and point your dish.

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.

Unusable Signal

I have exactly the same problem, with my RCA F27645. I can find no answers on the internet, so far.

I have 3 ideas.

1) The digital signal receiver must not be receiving the DVD signal properly.

2) Coaxial cable receiver (the little pin plug) problem

3) Digital TV (broadcasts) causing havoc on older TVs.

Picture does not bleed to edge

this symptom is caused by a poor regulation in the power supply circuit. too low dc supply voltage will result to insufficient deflection, both vertically and horizontally. black borders appear around the raster. receivers generally use regulator in the main power supply to set the dc supply voltage at the value that will allow the picture to fill the screen with a little overscan. defective regulator can result in a small raster. most modern receivers today are using ic (integrated cirduit) regulator. but if you are not inclined with this kind of job, better bring it to a qualified tv technician. good luck!
