AWA tv repaired - 3 times still not working right:(
hi
i've had to get my relatively new AWA tv model W571 repaired now 3 times and it's still not working right. $200 out of pocket and 10 days with no tv((((( F***! problem is perfect sound but no picture just a blue screen with white lines going across it.When you first turn on tv there is a faint picture like looking through a photograph negative,then within 5 seconds that goes leaving just the blue screen with the white lines. Repair guy gets it going in workshop leaves it running for several hours but whenever i get it back it goes again.First time i got it back it was ok for 4 days the second time i got it back within an hour the same problem ocurred. Trying to read original repair warranty is difficult because of handwriting but there are references to ''blue screen and flybook line''s.''Trace features to picture tube and tube socket''. ''Dislodge internal foreign material,'' then something that looks like ''heaters to cathode'',''short circuit on blue gun'' ''repair tele socket on picture circuit board'' ''replace heater dropping resistor & check plater circuit'' ''very extensive bench test''. The tv is only 14 months old I could get someone else to look at it but then i have to start all over again money-wise and i've already paid $200! Does anybody have any suggestions? thanks p***ed off tv viewer(( |

If you've got a heater to cathode short, there is no repairing by
conventional methods. Even a crt rejuvinator can't remove those shorts. The only way to do it, and it's not always 100%, is to defeat the heater line to the crt, meaning any path to chassis ground, and do a wire wrap around the core of the flyback. You're creating a new heater line free of the circuit ground. The cathode can short to the heater all day long and won't make a difference. |

well hopefully the technicial knows this?But maybe he only works along
''conventional methods? How would you know.?! It sounds like from your post (not a criticism btw) that the tv can't be fixed? |

I watched an interview with the Italian movie star Marcello Mastroiani on TV once where (paraphrasing) he stated TV is garbage, there is nothing good to watch on TV except maybe the odd documentary about animals. The man wasn't totally wrong except he didn't get the irony of being interviewed for TV. A*s*i*m*o*v .... This message transmitted on 100% recycled photons. |

The man wasn't totally wrong except he didn't get the irony of being interviewed for TV. A*s*i*m*o*v during my time studying media i attended a conference where it was revealed that with the proliferation of private tv and pay tv channels in Uk since the Broadcasting act 1990, the greatest increase in programming (over 100%) was: old nature films. So , that leopard you saw last week has probably been dead 10 years! But the channels are raking it in, just buying up old stock and repeating as opposed to actually investing in new stuff. Disturbingly, non-news factual programming, such as documentaries or debates, had dropped by 70% . So much for 'more choice'. TV seems to be there for the sole aim of making people ignorant and uninformed. Sad really given the potential for good use of such technology.... -rant mode off!- -B. |
