Hitachi Plasma TV no sound

Hitachi P50H401 50" plasma TV struck by lightning. I replaced the Digital Main Board and the Terminal Board, now I can watch cable through coaxial input with sound and picture. But when I hook up through HDMI, I only get picture, no sound.

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

I have a Samsung plasma tv that got struck by lightning and wont work. I replaced the power supply panel and it still wont come on. Do you know what else it could be.Could it be the actual power cord?


Chances of lightning damaging the power cord are slim to none, unfortunately it could be almost any board in the set, check the various power supply voltages on the boards and see if they are correct, almost every board has a power supply in it

Hitachi 2006 42HDS69 will not detect signal from dvd or xbox, how do I fix this?


Check the error codes on the digital board, which is visible through the grill in the back where the AC power entry is located. A trouble shooting guide, including the error codes, can be found in the service manual here: http://elektrotanya.com/hitachi_42hdx99_42hdt79_42hds69_chassis_dw2-u.pdf/download.html

In the case of my TV, I had to replace the main digital board. I was able to find one online for about $80 and replace it myself. Once you get the rear cover off the TV the digital board is easily accessible and took maybe 20 minutes to replace. Good luck!
