Sansui mdl hdllcd3210 will not turn on.

Did power signal lights appear?If there's no power signal lights,check the fuse,located at the power supply.If the fuse is good,maybe the power supply is dead.There's a leak capacitor in the power supply.Try to replace all the leak capacitor..The leak capacitor can identify through visual checking when you didn't know how to use tester.The leak capacitor is rounded top shape and have moise at the top,compare to flated shape of good capacitor.Thanks,hope will it help you..

Model TDC2075A Sansui Had lightning storm, lost power no close lightning strike. TV will not power up, don't know if it has internal protection or is power supply went out

you mite try replacing the ac fuse 1 time-if it blows again there is a short in the power supply-i would then check rectifiers in the primary of the power supply-then check the fet-if any of them are shorted replace them
