Question about Hitachi 46F510 46" Projection HDTV

1 Answer

Tv shuts off on its own

I have an Hitachi 46" projection TV, we have been having problems with it shutting down on its own. If you run the Tv with no inputs (dish or DVD) it will run fine. As soon as you change to say input 3 for the dish it will shut down anywhere from a few minutes later to half an hour later. It will continue to do this more frequently. We have had the repair man look at it in their shop. They had it hooked up to cable and it never shut down. We brought it home and are having the same problems. When the power goes out, you can use the remote and change the channel or increase the volume and when you turn it back on the channel will be different and the volum adjusted. I have no idea why the TV is turning off when we are trying to use the dish or DVD player, any ideas?

    hello there well to answer your question would it still work if it worked in the shop on my experiences with sets and customers i have learned that how many times have people taken things for repair just to find out that the problem did not exist.....sometimes shops do not leave things running long enough to anylyze the problem ......anyhow the answer to your question would be yes cause the tuning section in a tv has many curcuits and thus making some of them work and some not........may be that its only working iin a specific area and not in the other.....and the cost for such a part would cost in a range between 100 TO 300 ..sometimes when it becomes to costly depending on what the cost of the set is people have found out it would be wiser just to buy a new set...and have a warranty on it then to just replace a defective costly part just top find out that the part was just as expensive as a brand new set.....ive seen people say na its cheaper just to go out and but a new one ....i know walmart sell,s sets pretty cheap and there not too too bad........hope this helps ya

My hitachi prjection tv does not come on. It flashes the temp and lamp lights and then shuts down. Is my lamp burned out?

Chances are real good the lamp is bad. Open the lamp door, remove the lamp and see if it is shattered or scorched on the inside. If so, replacing the lamp will fix it. Only replace it with a genuine Hitachi part. The part number should be on the lamp cage.
Good luck,

Yellow and blue ghost warped top and bottom. shut it off it was fine , turned tv on 5 minutes later had problem

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

To get fixed either call in a local TV repair company or goto sites such as to get a repair kit with instructions.

I have a RCA HD52W59 TV. Shuts off automatically.

Power supply is my initial thoughts, but then again it could be that one of the three CRT's tubes has an issue.
My thoughts is that it would be best to bring it to a good TV repair shop.
Why spend money on a power supply and then find out it's a CRT.

Tv shuts itself off

Look for the computer processor inside the TV. It needs to be cleaned. A can of compressed air will work. The processor is overheating and causing the tv to shut off. Look for the small fan that is supposed to keep the processor cool then remove the dust.

Good luck!
