Question about Televison & Video
You need to qualify what was sprayed. Try using a mild isopropyl mix and an air duster can. Who knows if thatll help. Depends on what was sprayed and where on the unit.

My sister-in-law has exactly the same problem and is a common one with this unit.
I've spoken to a technician who says that:
1. Hitachi are withdrawing from Australia and there are VERY limited service centres left
2. The problem is a chip on the main board and depending when the TV was made will determine whether the chip is a plu-in or soldered on to the main board - if it's the latter, you'll be up for a main board at around $400
3. He couldn't get the price of the plug-in chip because he couldn't get through to Hitachi.

I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.
I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.

SOURCE: When I turn on my tv, I get a black screen that says unusable signal. I change the channel, same thing. I try to use the DVD player or another add on and it is still black. My TV is an RCA 37in flat s
Thank you ryolkowski!!!! We just tried your solution and MAN it worked like a damn. We were all ready to make a trip to the city to get a new tv, an expense we just didn't need right now. You made our day. I can't thank you enough. jabo

Sounds like the issue is with the set top box of your cable or direct tv provider. Please swap that receiver for the equivalent or a more updated version.If the problem persists. Verify that all inputs on television is correct. It should match. Output of source( digital receiver,dvd player) to Input( television ). Make sure all is secure. Good luck
