supply boards in this tv d and g . was hoping someone might know which
board could be bad so i might replace or even repair. thanks for any help
or advice. gary t
Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. you could have a bad High voltage spitter, a bad flyback, The horizontal output transistor could have shorted and took out a few parts with it. No one, I am sure my friend, will be able to tell you for sure if one of the power supply boards is bad and what board is bad on a case like this, unless they looked at the TV set and diagnoised it. The pops you heard could have been the High Voltage arching around inside the set, or maybe the regulator went haywire and blew up a few capacitors. If you have the electronic knowledge on solid state circuits, a service manual will be need to proceed with this repair. If you do not have such repair knowledge, play it safe and call in a service pro to assist you with this repair. Remember there is alot of high voltage inside these puppies even when they are unplugged. Good Luck and let us know what you found was wrong with your TV set.
thanks for the info and i do have a little knowledge and yes thank you am very aware of high voltage in some areas but needed somewhere to start with service manual again thank you and i will let you know how it turns out gary t
