These sets are famous for problems in the horizontal/high voltage circuit. Loose connections, bad high voltage transformers and shorted horizontal output transistors. If the picture was still good it is probably worth having it checked out. Thanks
Same Problem. TV was purchased from Sams Club about 2 or 3 years ago. workede great unti llast week. We were watching tv and it just shut off. The power button on the tv started to get soft were you had to push hard or just use the remote. My guess its something with the wsitch.
6/1/2010 11:34:21 AM Good morning I have sound problem it started with the cable hook up there box to the television, now sound is very low. Turn up the TV control to max, nothing but low sound. Of course cable people have no idea of a problem, I disconnected the cable but the same problem, love the set work for two years, note: thing happen when all analog change to digital. help!
there are two things that can cause this, 1 there is a muting transistor on the bottom of the PCB that is a surface mount transistor that goes short. this is the channel mute transistor. when you change channels it is designed to mute the static between channel changes. if it shorts then it mutes. 2 the EE-PROM is defective and needs to be replaced. i'de go with the transistor first. if you are unequipped to do this repair have a tech do it.
The power supply is in the protect mode. There is probably a short in one of the areas on the circuit boards. It is also very likely that there is a scan failure. The set would have to be properly troubleshooted to determine that exact failure.
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.
