Toshiba CZ27V51 27" TV 1999 - Picture goes out

One of the truly great Analog TVs that I have had for 8 years. The picture now gose out with a blip and a buzz. No line, just a black screen. However, if you jiggle the TV or whack it on the side, the picture comes back. This seems to be taking longer and longer with more jiggles and slaps, hehe. Anyway, once it "catches", it can stay fine for quite a while.

When the picture does go out. The Power On light, flashes slowly.

SOURCE: Power on but no picture or sound

Your problem is from the power regulator IC . Its an str type and has to be an original from tosiba or its parts distributors. Now you may have caused more problems as alot of peeps do trying the set over and over again thinking Oh the set will rest its self.. Nope sorry sir if a set goes bad and you try it once , and it dosent come back on . Its time to seek a repair person to repair and troubleshoot the set for you UNless your a technician? If your not Dont try to repair a tv as these have non serviceable parts for the consumer to replace! And can bite ya in the butt, if your not carefull. We techs cannot teach ya overnight how to fix something. Only assit and to point ya in the right direction. Good Luck

SOURCE: Toshiba 43A61 - No Picture, no sound

If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:

  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash. In this case, you need to call a service tech. Most of the time, however, the unplug/replug routine is enough to get the set up and running.

SOURCE: No picture Thin line across middle of screen

Hi,

Most problems indicated by your description involved the Vertical IC. With your post "tap...pop back up" signifies a loose connection or to be more specific a cold solder. I suspect that no part(s) need top be replaced but would however require re-application of heat with the use of a soldering iron.

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.

53" sony projection -picture washed out w/ green horizontal lines


It sounds like your Green CRT ( picture tube ) is shorted. That's the one in the middle. Sony had issues with there tubes in those years. Sorry for the bad news. Even if you could locate the tube, it will be a matter of time before the Red or Blue does the same.

Black box in front of picture


If it's the box,just press the CCD button on the controller until you see CCD off .(Try this one first since it just started with the box)

If it's the TV,just go into the setup options and turn off the closed caption feature.

Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .
