Don't know what is going on

Its real easy on this model when you replace the lamp for the pins on it not to line up perfectly when installed.

Mine did that and the red light was flashing it was the lamp. Best place to get one is ebay

sry no sol

The place to begin is to examine or have someone else examine the lamp this set should use for picture.

The "LAMP" LED light indication still light up,after all the other LED lights indications turn off?The tv projection lamp is dead.Require a new tv projection lamp.

After i replace the lamp on my Hitachi50v500a worked everything then i turn it off.After 1h wanted to turn it on again and it shows (TEMP) light is that a lamp fan or something else.Please help how to fix it by my self.Coz no money to call the tech.

Blinking temp light means bad lamp fan. Needs replacement

Good Day;
Try this:

Symptom: All Front LED indicators are flashing in sequence: Power-->Temp-->Lamp-->Power......continuously
Cause: Replace Lamp . This symptom may happen all the time or it may be intermittent. It is normal if it occurrs from time to time, See OG under TV Front Indicators explanation notes.

Good Luck, big IRISH.

Did you ever get a answer to this question? I have a hitachi 50vs810 with the same problem. I found the same sensor "tokin ohd3-90m."
I ohmed across mine and it shows open. I then held my lighter under it and it stayed open. I suspect this part is bad so I tried jumping it out. No change. Still have the same blinking temp light.
So... in the end I don't know if I tested it right or not either. Good luck and let me know if you learned anything that can help me out.

if the lamp has dies alot of the time to can look inside the lamp and see if it exploded (not always) do you get blinking lights?
