grundig flyback problem
Hi,
I have the problems of my tv esp the flyback, the tv is Grundig 25 inches M63-776/9 TOP. Why this LOPT, just can resist for very2 a short time before that leak and make a spark from the LOPT again and again and I already change twice with the new one. Whats the problem of this flyback? Very2 desperate ( is it just only cause the bad product or anything else? (fyi, I use the original from Grundig) Now my TV can operate only just for 30 minutes before the auto shut off turn the unit off at all. If this tv operate, its normal and before the tv off, the screen have a little flick a few times. The technician here, just paste the leak part of the flyback and the flyback make sound tick tick tick tick from the flyback, not easy to hear but there, like still have a little spark inside, so a little hard same sound from cup to the CRT. After operate for just a half an hour I thinked the flyback have a mild hot if I touched the body of LOPT. My question are, why this unit (the flyback or otherelse) have that problems? Power supply, HOT, and the other part of this tv its ok. I believed this trouble comes from the LOPT or CRT unit of this TV, have you ever found problem like this? Any info and help would be very2 appreciate. Thanks before. warms regards, Juang Siahaan Jakarta, Indonesia |

grundig flyback problem
The problem is that the tech is not fixing the original problem in the first
place. There are most likely other parts in the set that have to be changed to correct a high voltage regulation fault, that is causing excessive high voltage. If this is the case, the X-Ray emission from the set is probably also high. You should call the authorized service representitave for Grundig, or Grundig themselves, to have your Grundig set properly serviced. -- Jerry G. ===== "a'af" wrote in message om...
