TV searchs for channels everytime it is powered on
I have a GE 31GT659 Chassis CTC187CN. This TV was produced in 1996. It is used in a classroom setting on a cart so the TV never stays plugged in. We have a DVD/VCR hooked up to it and everytime the TV is plugged in and powered on it searches for Antenna/Cable channels which don't exist. We would like to TV to turn on and look at Video Input 1. This is a good TV still and I don't want to dump it, but will have no other alternative because our users won't tolerate and most can't figure out how to get the TV to video input one. Is there a battery inside similar to a PC so base settings are remembered? Can anyone offer any help?

The only thing i see is getting a UPS and plug tv into it. manufactures dont put batteries in tv's because most people dont unplug their tv. using a UPS to maintain memory and plugging UPS to keep UPS battery at peak charge

Possible that the power supply has issues and can be related to a faulty storage capacitor in the main circuit. If this has reduced in value then the + B will be low and so the SWITCH mode can be fluctuating thereby producing the low voltage effect. Please check the secondary + B and confirm the SMPS.
Ge is the most common universal remot make in the world, they make most all the universal remotes for everyone. Go to Walmart and get on for 10 buck or less and you will be back in business. With no channel buttons working this is your only choice.
I have a magnavox 31' CRT that did that to me. Turns out the power button on the TV gets stuck and so the slightest vibration of somebody walking past (wood floors) would cause it to power on or off. It would also keep the remote control from working until someone tapped the switch to un-stick it. Small problem considering the TV is 18 years old and still looking good.
your problem is called blooming
as you might be aware of very high voltage in tv.
you can check
1 high output voltage fron power supply.
2 if it is ok then the problem is in horizontal section.you can check cap.in hor. section
at last flyback transformer.
hope this will help.
The GE (actually RCA) 31GT659 has the notorious CTC187 chassis. This chassis developes cracks in the solder joints on the shields around the tuner and microprocessor, and can mess up the settings stored in the EPROM IC. This could result in channels going snowy, vertical collapse, loss of sound and/or total shut-down. The set should be resoldered and reprogrammed by someone experienced with this RCA chassis.
what do you mean that the picture streched out.this is a strange problem.as vertical problem does not strech it either have a line inthe middle of the raster, shrink both at the top and bottom of raster,lines run up and down on the raster.kindly explain your problem in detail then i will be able to help you.
