Question about Standard (CRT) Televisions
Cannot get power to set. There is no reset visible on back of set. Is their an internal fuse or breaker that could be changed by taking the back of the set off?
Have been told by tv repair people the set is to old to mess with, and even if one could find parts it would be very expensive to repair. Until this problem, the set worked perfectly with excellent color and sound. Set is used very little usually during holidays by grandkids.
Your tech could be correct... These were GREAT sets in their time and many are outlasting sets half their age.. When Mitsubishi announced in 1999 that they were discontinuing direct view manufacturing because they wouldn't compete in a throw-away market I was a bit sad as a technician because they were the cadilac of Tvs for how they were built. But alas everything does come to an end...
I would suggest checking the fuse at F901 for open. If it's open then it's likely C587 has failed and the horizontal output transistor. If F901 is intacted then you would need to do some trace testing with a scope to see past the smps what's happening to your power. You might try researching the NESDA site for a nesda technician near you. http://www.nesda.com/locator/state_search.php
Hope this helps!
