I have a 27" GE that powers up fine.....after a few minutes there is a loud popping sound from the back of the unit....also a white spark can be seen from the coil on the back of the tube.....sometimes the sound stays on but no picture.....then the screen comes back alive......sometimes the whole TV shuts off then turns itself back on......any help with this would be greatly appreciated....thanks in advance.....
Please post the model number and chassis number from the back of the set. With this information, we can provide part numbers and specific directions/instructions for possible repair.
