SOURCE: 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.

Toshiba 27A33. I can't find the manual channel button. Only the on/off button and volume buttons...

assumming your remote has a keypad with a bunch of numbers 1,2,3, etc those are the channels you press the combination of the channel number you want and press enter...sscrolling up and down thru the channels is probablymore what you want, and that should be located by a set of signs wghich has horizontal or vertical arrows right nex to each other...

Here is a link for entering the service mode just like they do at the dealers.

Here is the link for the owner's manual from Toshiba's American website (the Canadian site doesn't have this one available):

Lines at top of screen, about 4"

Hi:
This is due to vertical deflecton problem, there is some capacitors that has gone bad and need replacing. It might just be one cap rated at 100uf 35 volts. This is called vertical foldover eventually the top will fold over or you will get a 4" black border on the top of the scrn.

I have a toshiba standard tv 27A33. it has one

This television uses a feature called a V-Chip which allows parental control and consequently blocks channels of your choice. This set is approximately 7 years old and the owners manual is no longer available on line. You can over ride any blocked channel by entering the menu, select parental controls and enter the "secret" code. How one channel got blocked is a mystery. I suspect someone was exploring it's features when they accidentally blocked a channel. Normally the system control works flawlessly and if you have no other symptoms you need to reset that channel. That info is in the owners manual that came with your set.

Hi there, with my toshiba 27A33 television ,the picture comes in on both sides about 2 inchs

First thing to check: could it be aspect ratio - source material is old standard 4x3 format, TV is widescreen 16x9, so it only fills center? If so, the images will look properly proportioned - circles round (not ellipses), people neither unduly fat nor skinny.
Second: if the shapes are wrong, it could be settings on source device (check DVD menu, cable/satellite set-up) and/or TV (choices like letterbox, pan and scan, stretch to fill screen, etc.)
Third: if CRT TV, could be defect in horizontal sweep circuitry, requiring repair shop; decide whether the cost is worth it, vs new TV.

Good luck!
