Hitachi LCD TV looks like no power but power cord checks good

Sustain board fault. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

If power was disconnected with the set either on or off when it returned (the power) the surge may have got the fuse that is inline with the power cord or even damaged the power supply board in the set.

I would look first at the fuse and take it from there if the fuse turns out to be good.

That one I am fairly sure had a plug on cord---look where opening for cord is and inside for two metal pins in a socket---rectangular with white plastic.

Hello
Get into this link and see the suitable power cord top, to suit to your hoouse power socket. Then look at the abck of your Hitachi TV power in socket. Compare these and buy one. There is no special specifications. Choose a good quality one of a reputed company. That is all. OK

Did u check the pico fuse and all those resistors on the tv convergence board to make sure with ones are good resistors which are not good resistors and replace all them resistors too?U didn't do that should get it tested and replaces all those dying resitors.Try website like Tvrepairworld.com look up ur Hitachi tv model what resistors and pico fuse u require to check.

hi, try these steps...

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.

good luck!

Took it to a TV repair shop and they did the following:

1. Rebuilt Power Supply
2. Replaced Diode
3. Replacd Transitor

Total cost was ~$100. Tv works fine now.

the master switch at the bottome of the TV per Brianbuy solved my problem...Thank you!

Good Day;

To reset the TV unplug power cord from the wall for 2 to 5 minutes then plug back in.

Good Luck, big IRISH.

Good Day, ebfmays;
Check the lamp and (reboot) reset the TV by unplugging A?C cord from source wait 3 to 4 minutes then plug cord back in.
Good luck, big IRISH.
