Considering my experience I would say that you probably have a faulty
EEProm (Memory chip). normally 24c04 or 24c08. Not to sure on this model. Try obtaining from a local supplier. Not sure if this is a blank or programmed IC. Good Luck. |

If the set detects a problem, the front LED will blink a number of times, pause and blink again. Counting the number of blinks will indicate the inernal problem. If there is no pattern to the blinks, the set will remain in "startup" mode. This usually indicates a problem with the picture tube. A quick verification of this can be done by turning up the screen control on the flyback transformer. Note turn is just slightly. If the picture comes on, then the picture tube is starting to fail. Adjusting the screen control may give you some time, but that time should be spent looking for a replacement set. This "fix" won't last.

Thanks Dan, I think it remain in "start up mode" sense the led continue blinking and no partern of blinking. can you give more advice because I already turn the screen and focus, only the white line appears but no picture. what are other part to test other than picture tube?

| Now you're saying 'white line.' Is there just a thin white line in the middle of the screen that runs right to left/left to right? -------- in the middle? "But a solid line." |
