There is a componet that is heating up on the board then shutting the tv off when it fails, it is cooling off and working again. The problem is this can only be fixed with a diagram of the board to locate the faulty part. You will have to take it in to a service center for work. Sorry for the bad news, I hope this helps a little.

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!

TV does not power on. For the last several months I would have to unplug it then plug it back in to get it to turn on. It makes a clicking sound when plugged back in similar to the same sound it normally...


I have similar problem with my 42hds69. What I did is unplug the tv and remove the cover and vacuum everything especially the fan and remove the power supply board and brush/vacuum the back side... careful about static so hold the metal frame while you're vacuuming. Reassemble everything... mine worked... and still working... Good luck.

My 42HDS69 Hitachi has a recurring problem of not turning on. I unplug from outlet for awhile and sometimes it will turn after I plug in outlet, Other times it takes a few hours for TV to turn back on. ...


MY TV KEPT GETTING WORSE EACH DAY ALSO. BUY A CAN OF SPRAY AIR WITH THE EXTENSION SPRAY TUBE. WHEN YOU GET THE TV RUNNING SPRAY THROUGH THE HOLES IN THE BACK RIGHT ONTO THE FAN BLADES OF BOTH FANS. THE DUST WILL FLY OFF THE BLADES. A VACUMM HOSE WILL HELP PULL OUT THE DUST. ALSO SRAY THE POWER SUPPLY BOARD FOR DUST. I APPEARS THE FANS SLOW DOWN WITH DIRT ON THEM AND THE EXTRA HEAT BUILD UP JUST AFTER THE TV IS SHUT DOWN IS CAUSING THE POWER SUPPLY TO BE IN A SHUT DOWN MODE WHEN POWERED UP THE NEXT TIME. BEEN TWO WEEKS NOW AND WORKS PERFECTLY NOW AGAIN.

Hitachi 42HDS69 42 in. Plasma... Problem


Describe the past - How did it fail? One day or acting up for a while? Could be a weak power supply - a bad capacitor on a power supply too. Look for popped up capacitor top inside.
