Question about Televison & Video
I will look for a disc I have here with about 400 Hitachi big screen service manuals on it---this may be one.
The model number sounds familiar---This may be one of the sets that had a High Voltage cap that fails---You if able with set unplugged can look to see if the cap is on the main board--see attached part photo of it----Are you able if I tell you where to look to do so?
The location number which is printed on top and bottom of board should be (from memory) C707.
If it is found you simply take a good look to see if burnt on top or has a crack in the side of it.
If there, it and a fuse should repair the set.
This is what the cap will look like if this model has it:'
less than 1/2 inch wide.
With rear cover off there is a large (fist size) black plastic transformer with a large red wire coming out the top---to the right of this are a row of brown caps running front to back that will have what looks like hot glue across the top---the cap that is at the front (of the row and front of set) will have this blue one right in front of it, hard to see but if there you will find it--pull that hot glue off if needed as it is not essential.
Look for a tiny burn mark at top or a fracture of any kind in the side of the part.
If you find it is bad I will tell you where the fuse is that it destroys---sometimes when the cap fails there will be a snap or even the smell of something burnt.
Let me know what you find as I am here to help--do it for free.
