1 Answer

Hitachi 70SBX74b Won't turn on

We were watchin tv and all of a sudden it went off and we could not turn it back on. If I let it sit unplugged for a while and then plug the tv on I hear something turning on inside, so when I try to turn the tv back on either with the remote or the front control panel button the red power ligth goes on for a seccond and then goes off but the screen never comes on at all. What could it be?

Its the bulb you are looking at about $700 for one. You should get a quote first though. Also it may be the power box but if the light goes on for like s second and then turns off then it must be the bulb.

If you have any questions please dont hesitate to ask

Can you solve the problem of loosing all digital channels overnight on the L19H01UB television. Thanks Trevor.


Every time you shut down it may have arcing that zaps the memory of DTV stations. Just turn it on again might regain the list of stations. If not then scan the stations again in setup menu.

Tv went blank, wont come back on.


If those green lights on the board are going dim, then yes it should be repaired. This is likely a bad main filter capacitor on the primary side of the switch mode transformer. Should not cost over $150 at the most. Easy fix

If you ring Hitachi they should have repair service business. They should be able to tell you where and if not go to another electronic shop most of them are good (you got a bad one).

If you have any qiestions please dont hesitate to ask
