Sony 27TS27 chassis help please :)
Hey guys , i have a Sony 27TS chassis tv and i got it free !!! anyway i
replaced the multiplexer first off and resoldered the tuner and agc and jungle chip etc etc .. problem i am having now is it is flickering with the brightness , it will go from normal to dark picture and flickers back n forth from dark to normal picture and when it is working normally it has a great picture unlike before when it would lose tuner and go to snow and might i add that the sound was distorted due to the multi of course .. any help on this would be appreciated as i am no longer in the service field and not a member to tech web and others where i used to get tips from ... thanks for any suggestions ....

Check for dry solder connections on the board to
the left of the board that has the Multi on it. Check for same on CRT base PCB and else where. Also measure the screen voltage and make sure its steady, source is from IHVT watch for bad resistor and diode. kip "bloggybob" wrote in message ...
