Hitachi LCD Television

My Hitachi television is stuck in standby mode. It will not come on using the remote control or the manual on off switch on the rear of the set. However there is evidence of the mains supply with the red standby LED illuminated. This television uses the 17PW15-8 power supply

Any points I need to be checking?

    My Hitachi LCD television is stuck in standby mode. It uses the 17PW15-8 power supply. Neither the remote control or the local on / off switch on the rear of the tv will switch it on. I am really looking for answers on the component level. Any ideas on exchanging components to effect repairs.

You said that your tv has power right? so in this situation your power supply has not to do with this problem. it should be work by an expert technician with tools in this matter. if your tv is cover on a year warranty, then dont hesistate your self go and repair it.

How do you line up bulbs with remote


This set with front grill removed has a tiny blue button on front edge of chassis on left side that will manually take set to convergence mode but you must have the Hitachi working remote to do adjustments---different buttons on the remote adjust and save the adjustments, I have the Hitachi book that shows all remotes they use and which buttons do what---if convergence is real bad most likely the two chips for convergence need to be replaced if Magic focus will not help.

When switch on power LED comes on and goes off in about 7 seconds and then the STATUS LED comes on. Please tell me what I can try.


if you have the habit of leaving your device in standby mode (switching off in remote only and switching off the power supply), you have to consult a service perssonnel and get your circuit chip dealing with the power supply inside your device. it might have busted up if you have the practice that i specified. please do not leave your device in stand by mode for a long time..

Change from TV mode to AV mode for a Hitachi C28W4110SN


There should be buttons somewhere on the TV itself to switch input modes. Look around where the power button is located and see if there is a menu button you can access. Then use channel up/down and volume up/down to scroll thru modes to find input

Hope this helps

Cannot program tv using bell satellite remote


Turn your TV on.
Press and hold the TV mode button until all the other mode buttons light up.
Press the blank POWER button. (If your remote only has one POWER button, press that one)
Press the UP ARROW button repeatedly until your TV turns off.
Press the POUND (#) button to confirm.

My hitachi lcd will not come out of standby mode it uses the 17pw15-8 power supply. have you got any ideas


stuck in standby can be caused by c877 and c878 both box type caps 15n 400v. But the fault which is causing most of this is Q837 suface mounted transistor type bsh103 which is connected to pin 8 of sg3525a control ic807.

Good Day;

Take off grill, take off panel, on left side on front of circuits you will see a small switch. Push button. Remember to save data after adjustments are done via TV's remote.
