OK I have tried everything. I have ordered the STR30110 regulator from 2
parts houses and when they didn't work I ordered the original from Emerson
who told me the set was made by Orion and sent me an original Orion
regulator(STR30110). None of them work there is no control on pin 5 (should
be 7 volts dc). I took one out of a good working Emerson tv with the same
regulator(STR30110) and the set worked fine (7 volts on pin 5) has anyone
seen this problem.
