Hitachi tv turn off by itself when i get hot, how do i fix it?


Check for any air path obstructions and see if the fan is working, if not it needs replaced or checkd out. You can try and put a fan behind the unit to keep it cool this will sometimes work but the main reason is the set is getting to hot and it shuts itself down to protect itself from a failure.

I have the same problem as above. I have a Hitachi 50SBX78B and it was working great until some water from the plant on it got into the screen. Now the red light comes on for a split second, then goes...


Unless the main board is checked the damage to the board cannot be accessed. so open out the set and check on for any failure of fuse or fusbile resistors that could have opened out with the water shorting.
If water is still found use a dryer to warm off the moisture.
It area of the water spill must be checked for the possible damage

Tv will not power on


If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 
Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,

Nothing on my TV


This set has CRT guns. 3 of them. No bulb.
Check and see on this site what others have suggested for your problem.

Without seeing it I'd say main AC fuse

Lamp flickering


Well jumping has nothing to do with lamp so called bulb.
You have what I would call a cold solder joint.
You're going to have to open the set and tap gently to see were it is comming from. If you know anything about soldering they you will know it is not that easy.

Once you think you have found the place were it seam's to be the place were it make's it jump more often, start again to make shure that's the spot and not the hole area.
Then remove the board and resolder,

Good luck

If the power supply board is the only thing affected, I would suggest calling PTS:1-800-844-7871 and give them the model and what you are looking for. This would be the simpliest thing to do. They rebuild boards and maybe more cost affective than trying to repair yourself. Hope this helps!
