I have discovered that applying light pressure on the video card with a plastic shim corrects a card solder problem with these TVs. (Removing the back is required) In these cases you should be able to see a picture by shining a bright light right next to the screen front. This goes for many screen shutoff problems on flat panel monitors and laptops. Do not put the light there for very long or you will end up with a permanent bright spot burt onto the screen.

Trying to connect my inspiron 15 to my toshiba 32af44 and i can't get a picture on my tv. I have bought a pig tail that goes from VGA(the lap top side) to s-video/audio-video cables(tv side) but still...


> I have bought a pig tail that goes from VGA(the lap top side) to s-video/audio-video cables(tv side)
A simple pigtail won't convert VGA to S-video. The VGA output consists of separate RGB lines and horizontal and vertical synchronization lines.
If you have an adapter that really converts VGA (this output has no audio path) to S-Video and audio lines, then you probably just need to re-select the input through the TV's menu system.

Sony trinitron xbr screen periodically goes black. The audio stays on but the video cuts out.


Sony sets have several protective circuits that blank the screen if something happens that might damage the picture tube. One of the more common causes is trouble in the vertical output circuit. Given the age of your TV (the XBR models have been around a while), this might also be a symptom of a picture tube starting to fail. Most of these sets have circuitry (called AKB) that adjusts the color drive signals to the picture tube to keep them balanced. If one of the colors is enough out of range the screen will blank. It might be the tube itself, or failure of some part in that AKB circuit. The set might also have defective parts in the input switching or video processing stages.

Unfortunately, I can't suggest any place you might look if you want to try repairing this on your own. This kind of trouble usually needs to be diagnosed and repaired by a professional TV technician who has the service information to track it down.

Hope this has been helpful. Thanks for using Fixya!

Have a toshiba 27df47 flat screen tv. how do you


Hi there,
First make sure the video inputs are not locked using these instructions:
To set up the video lock:
1. Press MENU, then press or to display the LOCKS menu.
2. Press  or to display the password entering mode.
3. Use the Channel Number buttons (0-9) to enter your password,
then press ENTER. The LOCKS menu appears.
4. Press  or to highlight VIDEO LOCK.
5. Press or to select:
• OFF: Unlocks all video input sources.

Then it appears that choosing Video 2 using the TV/VIDEO button should enable the front input.

An entire manual is avialable here that should closely match your tv:

No picture, only sound


The set has a shorted vertical output IC, probably a TA8427k. The capacitors around the heat sink of this IC dry out and cause the IC to run hot. The correct repair is to replace the vertical output and the electrolytic capacitors near it. Also use 105 centig instead of the original 85 centigrade. The is some time a pico fuse or current limittng resistor which must also be replaced. This a common problem with Toshiba and is not a bad picture tube. The usual cost of this repair is around $120-150 depending on the integrity of the technician. Scrivitron
