12-04-2012SERVICE MODE TV TECHNIKA LCD 37-207Hi, who can help me to set the service mode TV TECHNIKA LCD 37-207 ?. thanks
12-04-2012Vtech thanks for the response. I should have been more specific. This is one of several diodes in a switch-mode PS from a Tascam/Teac semi-professional sound mixer/PC interface. I have a schematic for a similar model that uses schottky/barrier diode
12-04-2012I meant to mention the presumably schottky/barrier diode - I tested out of circuit, of course. . .
12-04-2012about code,thanks for your reply, but i don't have the manual, a tip to piont me in the right direction would have been great,thanks anyway,.

13-04-2012Ok, I see. Assuming the 48V in question is scan drived, you must use a fast switching rectifier. The main reason behind using a schottky is to provide the lowest possible drop across the diode & less noise. Are you saying there are 2 diodes in the
13-04-2012Possible solutionJust as a resource to others for what seems to be a common problem - I've recently encountered the same issue with the identical Eiki model. I suspect one of the surface mount electrolytic capacitors was at fault near the STR-Z2156, but changed all the e
13-04-2012Component IDAhhhh . . Fast or ultra-fast recovery diode - that's most likely the problem. I didn't think of that! The rectifier I subbed (IN4007) is in the secondary side, conventional half-wave config with filter cap-series choke-filter cap configuration. I didn

14-04-2012Does the intensity/brightness/focus has any effect on the missing part of the trace?
14-04-2012no, the problem persists at all intensity levels, some more playing around and i have been able to see some wave forms but not square ones. wierd huh?
