Great picture, but this last year it just started to turn itself off after anywhere from 1/2 hr to 2 hrs rare maximum! Seems like it overheats or something? help!

I own the 50inch Hitachi television model# : 50fx18b/ serial# : v6h004891 and I have been experiencing the same problems. I turn the television on and it'll be fine for not even 15 seconds, then it will just shut itself off. I have tried to research the problem but, I'm not having much luck. Any suggestions would be greatly appreciated. Thanks!

Resolder the horizontal driver transformer and all of the coils that start with "L77xx" on the left side of the sweep board, there is also a jumper staple just above L7711 that must be soldered it does not have a designation number but you`ll see the solder is bad on one end, very common issue with your model.

Can anyone point me in the right direction?I have had my samsung DLP (model SP50L6HD) for 4 years. This morning my children were watching TV and the tv started turning itself on and off. I switched it...

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Emerson EWL20D6 TV turns on and the picture goes right back off

Mine is doing the same thing. I talked with a local repair guy over the phone and he says that (obviously) something is malfunctioning in the TV and a sensor shuts it off to minimize the damage to other components. This would be ok if the TV were 20 years old (they used to last that long); however, mine is only 1 1/2 years old and Emerson couldn't give a damn that the TV is a piece of ****. Silly Mimi
