13-01-2008 | Hitachi Q777 shorted? | [quote:bd534e76b7="minnie"]C707, a blue cap usually gets a pin hole in it and takes out E994. Take a meter and see if E994 is open. The next common is Q777 shorts. I looked at the print and I don't see a thing with 3 humps. When you get a location post it |
13-01-2008 | | Is the TV generating any EHT? Is the sound ok? |
13-01-2008 | | My bet would be dry joints in the PSU aera. If you know what you're doing, unplug it and open it up to check for any broken solder. |
13-01-2008 | | A short between the emitter and collector is normal, base to emitter indicates a shorted transistor. Remove the transistor and see if the set stays on. |
13-01-2008 | | K, then it is strictly used as protection if/when there may be a spike. otherwise a passive component that has no other effect whatsoever
Curious as to why you think it is intermittent! and exactly what is the problem/symptom that leads you to believe |
13-01-2008 | | If it's not the panel,
Westinghouse 5600600039 Pwb Assy Main Bd Lt32egn
I would suspect the digital main board.

13-01-2008 | | I'm replacing the resistor because it gets pretty hot and I plan on raising the new resistor a little to help keep the heat away from the board. I'm in there replacing some caps so, while I'm there....

13-01-2008 | | hi
Do you know what determines when the motor should stop? Is it the mode switch or is there a switch or sensor...?
Thanks |
13-01-2008 | | Unless it is a very old model it will be the mode switch. Otherwise a visable leaf switch at the top of the deck. |

14-01-2008 | | Why would you expect it to be working? It's in pieces....

14-01-2008 | | It wasent working, so I took it apart to see if something was wrong, I tried putting the plate back on, but it still didn't work. |
14-01-2008 | | sorry, not familiar with Hitachi's. Perhaps minnie can chime in & give you some pointers. though I can assure you that "capristor" has got nothing to do with your problem. |
14-01-2008 | | Typical signs of corrosion due to spillage of a "sugar based" liquid (ie Coke)

14-01-2008 | | have you checked the fuses on the sus pcbs? a blown fuse will mean the power supply has no work to do and so the set will not run. i must admit i have only seen about 20 of these sets and dont know how reliable the psu is but i do know the sus boards are |
14-01-2008 | | Yes, it should be no problem to use a regular zener diode. Its purpose is just to limit the +96 voltage in case of trouble in the power supply and salvage the rest of the chassis. |
