Question about Hitachi 70VS810 70" Rear Projection HDTV

1 Answer

Won't turn on?

Yesteday my 70VS810 made a "buzz" sound and shut down. Now it will not turn the screen on and the "lamp" and "temp" lights flash in red when it tries to power up. The lamp fan does run, but no picture. Is this something simple? The warranty place is telling me 3 months until they can even look at it. I am hoping it's a fuse or something. Thank you in advance

You need to check the lamp itself,sometimes they just blow up like a bulb does and if the lamp is good make sure all the fans are running and all compartments are close properly like where the lamp sits.Set needs to be unplug from the wall while you check.The wainting is not acceptable for 3 months.Let Us know if you need more information.

Dell 1209S Projector, tries to turn on, and the fan comes on for 30 seconds and then goes off again. It tries this several times and then the light bulb icon comes off and it doesn't do antything else


Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.
LAMP light is solid amber If the LAMP light is solid amber, replace the lamp.
LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down.
If the LAMP light is blinking amber and Power light is solid blue, the color wheel has
failed and the projector will automatically shut down.
Unplug the power cord after 3minutes then turn the display on again. If this problem
persists, contact Dell™.
TEMP light is solid amber The projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down. If the problem persists, contact Dell™.

Hi Charles,

Sorry for the late reply, I'm offline upon purchasing my service.
You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.

As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit.
However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).

I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown.
I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.

Samsung model hlt4675sx\xaa projection tv wont work. the stand by/temp light flashes red and the lamp light flashes green? it makes the sound that it makes when it turns on but no picture. we looked at the...


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

Burned out lamp?


First. Turn on the set and see if the Lamp Illuminates, If so then you have a bad Color Wheel. If the Lamp does not light up, you have a bad lamp.
Take out the lamp and look to the center of the lamp. If you see broken glass inside you have a bad lamp.

If you hear the Lamp fan turn, it is probably the lamp it self that has failed. If you do not hear the lamp fan turn then the fan could be bad or binding.
