Question about Hitachi 70VS810 70" Rear Projection HDTV
Hello, I have a Hitachi 70VS810 that just started going out. I'll be watching TV and the picture will fade away, go out without sound too. The power button blinks fast the whole time its out. It stays out for 30-50 seconds and comes back on. It works as it should for about 10 minutes and goes out again and keeps repeating. Only once did it go out and the temp light came on. I have checked all 3 fans and they all are working. I took the lower back panel off and had a standup fan blowing across the whole electronics. It it were a temp problem, it shouldnt have gone out with that fan blowing. But it did. I dont know what to check next. I thought about disconnecting the temp sensor to see if it stays on but I cant find it. When I search, the results come up for the 50inch. What it shows in the picture for the 50"(a yellow wire)isnt like the inside of mine. Please help! THANK YOU!!

Good Luck

First off check your lamp or replace it. You can never have too many lamps..........in the last minutes of overtime ! Are you kidding Me! If lamp doesn't work, you will need to find qualified servicer. Try craigslist or tv repair in yellowbook

Good Day, you all;
The front panel light on Hitachi TV does not really tell you much. To see what the TV is doing or better said NOT doing is remove back from the set.
If you are not a technical type person, it would be better to consult an authorized service center, but if you are perform this; 1. Remove back
2. Observe led and notice which once light, there are as many as 9 LED's.
Now that will tell you what area of the TV's circuits are to be concerned about.
Let me know, Good Luck, big IRISH.

I have the same problem with mine, I can also do the ol Fonzy hit it on the side and the sound will come back on. I have re-soldered many bad looking solder joints and I have finally tracked it down to a part # LSK1aF-5v it is located on the board that the main power plugs into at the very back behind a large transformer. The part can be found at parts.o2xygen.com/parts/l/46.html .
