You take a flatscreen TV, and you do what you can with it, based on experience. A lot of the time, its a case of going down the manufacturers' preferred route, of board swapping. That said, power supplies and backlight inverters are often repairable. So what's the problem ? Good possibility that someone on here might know the answer, or be able to point you in the right direction. If you never actually ask the question, you'll never actually know ... Arfa |

It was working fine, then didn't work? This suggests a possible change in
reception conditions. You should definitely swap the sets, as suggested. However... You've lost SD reception (SD being 625-line PAL), but not HD, right? As far as I know, SD and HD use separate tuners. (I think.) I could be that the SD tuner has gone out. |

Do you mean just the front end, or the IF section, too? Given his description, it's hard to believe it was caused only by a change in signal level. We'll have a better when he swaps the sets. |
