Measurements have to respect values according to service manual diagrams.|
|11-01-2011||i found problem.i replaced C827: 4700uf/16V .
this cpacitor was not short-cicuit but it was leaked.|
|11-01-2011||I have replaced convergence chips and checked resistors but no luck. Also, Red LED in front of TV cuts on and off like the rest. I am certain that it is not a code. To see a video of what the TV is doing go to the link below. Hope this helps:
|11-01-2011||So proceed down the "blinking" branch? :)|
|11-01-2011||1. Proceeded down blinking branch.
2. Observed LEDs.
3. Are 4 Green LEDs turned OFF at the same time? Yes, all but D913.
4. Does raster Appear with (6) and (5) Of PPD4 shorted? Yes, but the raster also appeared when (6) and (5) of PPD4 were not shorted|
|11-01-2011||i do not have an oscilloscope is ther any other thing i can do or checkh|
|12-01-2011||Did you try turning up the screen control on the flyback?|
|12-01-2011||I took "YES" route and checked Q903 and Q904. They were ok. Resistors R948, R949 and R950 checked ok. C948 was replaced since ESR was high. This still didn't correct the problem.|
