Toshiba CZ32V51 help with repair

Apr 30, 2005 2 Replies

The subject TV, a Toshiba CZ32V51 exhibited the following symptoms intermittantly: Upon startup, it immediately went into failsafe mode with slow blinking front red led with black screen, no audio or video. After about 5 - 10 minutes a normal picture would come on and last for as long as viewing. Occasionally the picture would "flip" with what sounded like it may be an arc over. I was able to get into diagnostic mode with the following results.



Self check 23906826 Power: 000 Bus Line OK Bus Cont OK Block UV V1 QV01 QV01S



Finally, it no longer went into normal video mode but I was able to do one more self check:



Self check 23906826 Power 000 Bus Line OK Bus Cont NG H001 Block UV (in red letters) V1 QV01 QV01S (both in red letters)



Seems to point to H001 the tuner? Can someone with experience with this diagnostic /set chassis series N9ES help me interpret it and suggest a cure?



Thanks,



Fred



I had one of these recently that made me crazy. It turned out to be a lead that was not trimmed that was laying over across a trace of the 12v supply (near the FBT) and was pinched between the board and the plastic frame. The coating on the trace had worn thin and it would short when the board was moved around.
