Question about Hitachi 70VS810 70" Rear Projection HDTV

1 Answer

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.

This is more likely to be an issue with your power supply not being able to supply the correct voltage to a certain board all the time. Most likely bad/aging capacitors. You could probably find a new repalcement power supply board on line. Check with Shop Jimmy, they may have one fairly cheep.

Sony KPR-53EXR15 pictures fades in and out


Sounds like possibly it could be connection related between any AV/Cable ports. Worst case would be the capacitors of the motherboard leaking. It's possible to fix anything. Just make sure you have the knowledge and the right equipment.

I have a Hitachi 70 inch lcd rear projection tv (70vs810). When the tv is turned back on the screen is very blurry. We have had a problem with it over the past 6 months but it would go away after warming...


This is a well described problem with model #. Thanks for that. Now it could be a tv lamp at the end of its life if the tv lamp is around two years old. Its easy to change lamps and the procedure is explained in owner's manual. If the lamp was replaced recently or the problem stays even after changing the tv lamp, its the optical block going bad. That need professional help and you should not try to mess with it. Check out at www.fixurtvs.com These repairs could be expensive and may be wiser to go in for another TV.
