Weight of TV set

It souds like a bad power supply and yes it is preferable to have it checked by a proffessionnal tech. I could be wrong !

replace flyback

You did not specify what brand of remote you have.....The GE set you have is the same tv as the RCA and should have the same code#.

Change your tv setting to cable!

odds are high volt  circuit gave up. 100 150 repair 5yrs not worth repair.

Do you have the remote control for your TV? If so, try to program again your TV and if nothing happen, replace the eproom and the the tuner.

My best answer is check with your local TV shop for any service manuals. Most TV companies do not sell parts or information to consumers. This is true for RCA/GE as well. You can google search your TV model and see if you can find any info.

In google type GE32GT40 service manuals.

Hope this helps!

Yes it is called an EEPROM IC chip that needs to be replaced. Very comon to fail on these types of sets. GE owned RCA back the 1990's now funai owns both along with magnavox and parts may be hard to get.

umm well have you tryed to go in to the menu and add those channels back?

The GE (actually RCA) 32GT740 uses the CTC203 series chassis. The most common problem in that chassis is a coil connected to the base of the horizontal output transistor comes loose, and the set may run sometimes and then it will shut off by itself. If you keep trying to run the set with the solder joints cracked on that coil then the horizontal output transistor will short out and the power supply will squeel when plugged in. Do not plug the set in if it squeels as this could eventually cause major problems in the power supply. The set needs a new horizontal output transistor and a good resoldering of the drive coil, drive transformer and all related parts. If you do not have experience in unsoldering and soldering electronic components in TV's then have a qualified tech handle it for you.
