hi I have a question . Is the tv a plasma? if so try turning down the contrast. These give off a lott of IR and can screw with remote sensors.
good luck !
I am not familiar with that set but there is another cause for an hour glass.
That would be the cap for the horz power supply. If you have a line derived power supply. If you have a smp supply then this would not be the case.
Good luck
Re: TEKTRONIX 2225
Sorry my schematic is for an 2205. I dont think that will help but if my memory
servs me I got it off ebay for 15 bucks and they had many tektronix mods.
98 percent ot the time the flyback is the culprit. U will need a variac to bring up voltage slowly and check supplies coming off the flyback. If the set uses a smp supply U will need to ring the flyback for shorts.
hope this helps.
Looking for orion hcca 225 D schematics. It seems like no one has a source for these amps.
replaced some mosfets and power transistors in the output stage. Now it takes about 10 min to come up. Traced it back to two jfets controling the gain of the last op amp but from there the circuit...
