Toshiba colorstream 27A33 TV

When I turn my TV on, white horizontal lines appear in the upper 1/3 portion of the TV screen. When they first appeared, when I turned the tv off and then back on the lines would eventually go away. Now the white horizontal lines seems to be permanent.

Re: toshiba colorstream 27A33 TV

1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.

Horizontal white lines 27A43.

You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

No picture no sound

Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

Poor picture quality

You need to consider the following tips herein as follow:

1) Field collapse (horizontal white line on screen)
R710 dry joints. Same as C2146TN & C2546TN problem solved with thanks to Mike G & Barty. Power off/unplug. Get to circuit board underside with aerial socket up-R710 is near top and right of centre-cluster of 4 joints best resoldered
2) Picture is horizontally narrowed and deformed
Capacitor C2913 (390nF, 250V) on the deflector PCB had lost capacity

Please let me know any update

Top section of the picture gets reversed and compressed

Dear simon, Seems like a simple problem. In all likelihood, one of the Electrolytic Capacitors in the vertical Output stages has failed.It could also be a cold / dry solder, as symptoms seem to disappear when you tap the set. But, do not try anything thing at home. A proffessional Techie should fix it up in 15-20 mins. Definitely worth the spend.
