Question about Hitachi Televison & Video

1 Answer

I have a Hitachi 50VS810 TV that is about 4 years old. Was working fine, went to turn it on, and the ''temp'' light flashes in a sequence that indicates a ''fan failure'' I opened the case, and removed a rather large Nidec Fan from right next to the bulb. I found a replacement fan online and ordered. Problem is i noticed another fan in there also, just way further back, and not that easily accessible. Also, when you replace the fan, is there something on the board that needs to be re-set? I do computer repair for a living, so i am not afraid of digging into this, i am just worried that there is more wrong than just the fan, and would like to get the parts ordered, but am unsure of how to test/troubleshoot.

The fan next to the bulb would be my guess as the only problem. No sense digging unless needed. Replace the fan first, turn it on and see. There should not be any reset needed.
Hope this helps,

When I turn the TV on, the Lamp and Temp lights blink red. Then the TV shuts down after a minute. Do you know what the cause is?

How long has it been since the lamp has been change? If the lamp went out, this would cause this problem.

I have a 50vs810 dlp. The blue and red lights flash in sequence when I turn it on.When they stop flashing the red light for the lamp is on. The yv has no volume and no picture. Is it just the bulb or does...

More than likely, it is the bulb. My hitachi 50v715 would come on(light up and show picture) 3 to 30 sec's with out the lamp indictor even lighting up. Put a new bulb in and works great. So I would try a new bulb. Look in your manual for the bulb number. Buy an original hitachi bulb they last a little longer.

Sounds like the DLP lamp failed. You can decipher the Hitachi flashing red light. That should help to be sure.
The DLP lamp replacement is fairly straightforward and can be done with minimal tools

If the set comes on momentarily, see if the lamp fan is turning. If not , the fan is probably bad.
Hope this helps,
