Question about Televison & Video

1 Answer

Toshiba ce27f15 I have a Toshiba CE27F15 27" TV, vintage 1996. The video input works fine, but the cable input is breaking up the signal, audio and video. It's thermally sensitive, as the problem improves when the set warms up for 20 minutes or so. Sometimes it clears completely. I haven't cracked it open yet because I don't have a schematic. Any ideas where to start? Is there a free schematic available somewhere on-line? The set works great other than this, but it's not worth putting much money into since it's so old. But I'd like to give it one good attempt at a repair. Thanks, All...

Since it's thermal...the problem probably lies in the tuner circuitry...but it would be a good idea to rule out the obvious first...such as a cracked solder connection at the connector. Try physically moving the cable around while the symptom is present to see if it changes. Or try some freeze spray on the connector after it starts working. If it's thermal...freeze spray should make it fairly easy to isolate in or near the tuner.

    Sorry...can't seem to find any free schematics. Sam's publishing has a technical manual for $20. You can search for it using your model number on this web page.

I need a manual for an SD310VU MODEL it was given to us but we do not know what we need to hook it up to our TV. Can you help us Thank You

Toshiba has the manual for the SD-310VU at their site: .

You can connect the DVD player to your TV either with composite video (AV), S-video or component video cables. For the best signal output, get component video if your TV supports it. So the issue is what inputs do you have on the TV. For an older TV with only a coaxial antenna input, you would need an RF modulator for the composite video cable. (These are available at shops like RadioShack.)

Composite video cables usually have 3 RCA plugs on each end (yellow for video, red and white for audio). S-video uses a different plug and then the audio is carried on a different cable (usually red and white RCA plugs). Component video cables use three wires to carry the video (YPbPr - usually colored red, green and blue). As with S-video you use a second cable for the audio.

Purchase the cable(s) that will give the best signal with the inputs that your TV has and connect the video outputs from the DVD player to the matching input on the TV. Connect the audio out of the DVD player to either the TV's input or your sound system receiver, depending on the speakers you want to use.

I hope this helps.

I'm trying to connect my DVD to the TV I can hear sound but can't get a picture and I get the message 'no video signal'

Connect the yellow video cable from DVD player to TV's yellow video input. See diagram below. Connect white RCA audio cable and red RCA audio cable as shown. Be sure to select the proper input on the TV.

Connected cable box to tv with some audio etc 3 plug thing and no signal

Make sure that the TV inout is worrking by connecting a sourrce like a DVD to the input. If faulty the TV input section must be checked.
Secondly if the TV works the cable line from the provider to the cable box must be accessed by a signal tester. call the service provider to confirm the signal or if there is any break inthe line.
Finally connect the output to the TV with the correct connection of the video( yellow) , the red and white to audio inputs.

Toshiba 40XV645U - No picture on HDMI 1 when TV is turned on

I assume that you have set the input source selction as in Page 32 and HDMI 1 is solid and and not grayed out. If so check the Preferences menu and see if there is an option for power on set up.
Also look at page 51 about HDMI feature settings. I assume you turn the cable box on first before turning the TV on.

8' Optical Cable from TV to Receiver and Signal is Breaking Up

Before you buy anything try checking the AUDIO Settings in the Menu of Each Device (Mostly TV) and see if they are set to PCM or BITSTREAM. HDMI is mostly set to PCM while Optical is generally Bitstream. The TV may be set to the opposite of what it needs to be. I would try to get PCM to work first cause it is Better, If not then set what you can to Bitstream and it should pass. Also check in TV Menu for SOUND OUT or AUDIO OUT or SPEAKERS. Some TV's have a problem passing Audio through when they are already Outputting them to it's own Speakers! I Hope this Helps out!

Toshiba no video sound is fine

If you can see the menus this means the CRT, high voltage, scan amplifiiers, the output video processor, and CRT drive circuits are working. The fault is most likely in the video section of the input select circuits.

Maybe the Toshiba parts department can supply a service manual for your set. With a signal source, a scope, and a DVM, an experienced technician can troubleshoot your set to locate where the failure is occuring.

I have not serviced this model, but in other models I have found the main input select IC to be defective. In some cases I also found a bad voltage regulator IC that supplies the input section has failed.

Toshiba Model: SD-V295 DVD/VCR Combo Setup for TV recording

The proper hookup is antenna or cable into the VCR RF/antenna input, then VCR RF/antenna output to the TV RF input. The hookup you describe means no signal is getting to the VCR.

With some TVs, there can be Video and audio output jacks which can be hooked to the video and audio jacks of the VCR. However this would likely mean you could only record the channel being watched, and, the TV would have to be on.
