Chassis is ATC010a. When i plug it in, it makes a clicking sound. When i press power...it turns on for half of a second and then goes off. The green power button flashes over and over and then stays on after a while. No picture, No sound. I need assistance with this. I found this TV...I know alot about computers, but TV's lol no way. Can u help me?
I Just started to service one of these RCA ATC-010 chassis,I found a shorted Horizontal Output transistor 2SD-3402.
This could be just a failure of the transistor itself or the transistor failed because the flyback transformer has either shorted windings or internal diodes. These parts are not expensive,I suggest replacing both at the same time to save yourself future aggravation.

A blinking power light would indicate a problem on the chassis board located inside the tv. Possibly a failed flyback or other electronic component. Its not cost effective to repair when you can invest in new tv for the same cost as repairing the defective tv. I should also mentioned the danger of dyi troubleshooting of the components inside the tv. I do not recommend unless you are familiar with properly discharging the tube to avoid electrical shock.
The first thing in this unit is to check the ribbon cable that goes from the front control panel to the back ssb board, I would unplug and replug to make sure seated properly. Then try it again. There are alot of screws to take out but worth it if this solves the problem.
This sounds like something best handled by an experienced tech since the fix involves extreemly high voltages nearby, If you have a very good knowledge of the inner workings of tv's then ask for more information.
If you blew the fuse, the TV would do absolutely nothing - no lights, no sounds, nothing. It could be that the loud zapping noise you heard was the high voltage transformer arcing or shorting out. This could have caused the horizontal output transistor to short, and the set will not start as a result. You should have the set serviced by a qualified tech.
I have the same problem-still troubleshooting...so far still not find the cause. DM1 power supply output voltages are operates correctly. Signal output of microprocessor up and down (no good) that turn on Q14105 and latch optical isolator U14102 to power the unit but both of ohmed out ok. it hard to troubleshoot the main board with power on.
The GE (actually RCA) 31GT740 uses the CTC203 series chassis. The first thing I would do is resolder the coil on the base of the horizontal output transistor and the pins of the horizontal drive transformer, as well as any other solder joints on the main PC board that look weak or cracked. 9 times out of 10 that cures the symptoms you described. If you do not have experience soldering parts on PC boards then have a qualified tech handle it for you.
