Question about Toshiba 27AF42 27" TV

1 Answer

Poor picture quality

My TV is unwatchable. The picture appears to be totally out of focus with horizontal white lines. There still seems to be color. Sound is fine. The TV is nearly 5 years old. Is this tube shot? Thanks.

    My set (3 years old) went out yesterday with same symptoms. Picture appears blurry, ghost-like, with vertical fuzziness and white slanted horizontal lines.

    Picture is fuzzy with grayish-white cast to it, as if looking through thin film of white gauze. Everything VERY out of focus. Sound ok. Color ok. Manufactured in Jan 2003, so 6 years old now. Previous problems with power button getting stick pushed in, also plastic door falling off the little section that contains front-side auxilliary input jacks. But never any problem with the picture quality until now.

    Can someone please review this solution, in light of the new instance of this problem I (broyer3) just posted? Also, a little more English and a little less technical jargon in the solution would be helpful. I need to be able to read this aloud to the TV repair people I call on the phone to ask for a repair estimate based on this problem and your recommended solution. Thanks!

1) Field collapse (horizontal white line on screen)

AOC PD4264 Screen fault


Extremely blue color temperature that cannot be adjusted; some false-contouring artifacts in dark scenes; no picture-in-picture; limited connectivity with just one DVI and no HDMI inputs.
If use as a TV monitor:
The number of colors you can display is controlled by the video card installed in your computer. In order to display more than 16 colors, the proper video card driver must be installed. Contact your computer or video card manufacturer to obtain the latest driver from them.
If you are watching standard-definition or Cable/RF signal on an HDTV, the picture may appear to be of poor quality. This is because the TV is designed for viewing HD or at least digital content. Your best bet would be to upgrade to a Dish Network HD receiver and connect it to the TV with an HDMI cable. Similarly inputting analog signal to TV from your DVD player will not appear to be of great quality. A newer DVD player would most likely have component video output which would look much better. To get even greater quality, an upconverting DVD player connected with an HDMI cable would look the best. You could also upgrade to a Blu-ray disc player, which is capable of playing HD Blu-ray discs as well as DVD's at higher resolution. A less expensive choice could also be a streaming media box. Hierarchy of inputs for good picture quality:

Horizontal hold does not seem to work. horizontal lines in pic


hi,
Is there is white horizontal thine line on all over the screen then the screen voltage of you TV is high. Can be caused by bad base socket in the picture tube neck, faulty focus/screen block. Check the two things. You can see the base socket at the picture tube neck replace all the three base sockets for the three CRTs. if problem remains then you have to replace the focus/screen block. focus/screen block is one through which you can adjust the screen voltage and focus voltage. If the potentiometer in side it have some problem then this problem can occur. Have added the image for two items for your reference.

Lines down screen


We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

When looking through the display screen the picture has a pink tinge. When reviewing the pictures they're definately pink in colour, especially the blues.


Try taking pictures and download them to a computer. Check the colors and evaluate the quality compared to what you have seen in the LCD display.
If the pictures are good and the colors seem to appear good on the computer, then some thing is either not adjusted correctly for the LCD or you may have a menu setting which is incorrect. Check all setting in the menus.
Test the camera again, and see what the colors look like in the LCD display.
If both the LCD display and the pictures on the computer are the same, then some problem exists in the camera, and may need fixing, or sell on a site such as Ebay for parts or repair as is.

Very poor quality pictures


Sounds like the sensor is bad, At this point it is better to just buy an new camera, as the cost to repair your old one may exceed the cost of a new one.

Picture broken and shrinking


You need to change your vertical IC, along with some capacitors around the vertical IC. Capacitor with value 220UF, 10uf, 470uf and finally 1000uf. Doing this will fix the set. Total cost under $40
