Vertical size adjustment on my GE 31GT660 set

The vertical size of the image on my 31GT660 is off the bottom of the screen. I can't see scrolling bulletins that come in from news services.

Re: Vertical size adjustment on my GE 31GT660 set

I had the same problem. I found the solution in this link.
The only thing that wasn't clear was how to get into the service menu. With the TV on, press and hold the MENU button on the front panel of the TV and press POWER then press VOL+.

The scrolling banners on the top and bottom of my zenith monitor are cut off. according to my manual, it is 1 of 6 models: SR2573, SR2783, SR2739, SR2773, SR3238, SR3273.

Either an adjustment of the vertical height or Lin or a circuit problem in the vertical circuit.

Some sets have physical controls inside the set on the board or in a hidden menu via the remote.

Yes there is but you have to get into the service menu and its a risky business to go there without knowledge of these adjustment.In any case these adjust would be called vsize,vpos.Any local repairman should be able to fix that in 5mins. good luck

Control of vertical TV image projected on the screen

You can try looking for 2 things

1. A button on your remote that says either: ARC, Ratio, 16:9, 4:3.... Some remotes have a picture of a square with arrows pointing out towards each corner..... I'm unfamiliar with this set, but it sounds like a widescreen, so give it a go

Hello bouloulou, Well let me tell you what you have is a loss of Vertical Linearity. This could be cause by a power supply issue or by inproper filtering of the dc voltage used to supply the vertical section of the TV. There used to be a control which allowed you to adjust this along with Vertical Size which controled the bottom of the screen. These days the signal processor chip takes care of this along with a few capacitors. I woould suggest that if you do not have a background in electronics that you take the set to a shop for repairs, If you do have a background in electronics, get a schematic for this set and the use your multimeter set to DC volts to measure the DC levels in the vertical section of the TV. Also you will need an oscilloscope to measure the ripple voltage on the DC power supply the schematic will show you how much ripple is allowed. I hope this helps. Thank you, Shuttle83

White Horizontal Lines near the top of my Screen

this symptom is what we called vertical fold-over. vertical fold-over is characterised by a white horizontal bar on the bottom or top of the raster due to the concentration or compression of the trace lines. it an image is present, the bottom or top portion is fold over. this is caused by a vertical deflection current with poor linearity, which compresses the trace lines at the bottom or top of the screen. this symptom is is caused by a defective sawtooth wave genetator circuit, or improper biasing or defective feedback circuit of the vertical drive or vertical output transistor/ic. the negative feedback circuit in vertical deflection circuit compensates for the linearity of the trace portion of the sawtooth wave. a decrease in the capacitance of the sawtooth generator capacitor is usually the trouble. but if you do not understand anything what i have written here, better bring it to a qualified tv technician for your own safety also. good luck!

Bottom of picture is cut off

Usually when the vertical starts shrinking slowly, it is due to capicators getting out of tolerance in the vertical output section of the chassis. If it can be adjusted out through a service menu, you'll probably need a tech with the right equipment to perform it.

Image adjustment for GE 24GP65

Yes you can adjust the vertical size in the service menu, but you must be carefull when doing any horizonal adjustment as this can shut down your set .

Your problem is not a vertical alighnment or size adjustment. No, Im sorry to say its the old vertical output IC and /or the small capacitors around the ic and in the vertical circuit. If you dont have the right tools, like a soldering iron a multimeter know how to read a schematic diagram, then you should seek out a repair person to assist you in this repair.
