06-10-2009 | Test/Measure Transformer | I have a transformer on a circuit board of my GE range. I'm measure 110AC on the pimary side but on the secondary side there are 4 pins, marked 5,6,7 and 8. It should have 24 DC volts coming out of it. From what I can remember in one of my undergraduat |

06-10-2009 | | After going through my purchase records I bought this:
Intel Pentium M Processor 770 2.13GHz 533 2MB SL7SL, which I think is the fastest the board could handle according to the service manual. Incidentally I think the board can handle 2Gb of ram not the |

06-10-2009 | | Tell him you want new! Tell him your not an idiot and the repair exceeds the value of the set! |
06-10-2009 | | Always? Sweetie I thought I had located a replacement part that had 24v for the secondary winding. Does that explain why there are 4 connections out of the secondary? Taking it from AC and turn to DC by way of some diodes on a connected board? Then it |
06-10-2009 | Huh? | Hmm.... :?
Are my questions really that hard, or am I being too intrusive?
I can see lots of imprecise and nonconclusive questions answered, but I'm giving my best to be as precise as possible yet received only a few replies.
Perhaps this TV set |
07-10-2009 | Need Help | I was wondering if any one could help me. I am trying to find a power board for this tv. Mitsubishi VS-60703. The number of the board is 930B846. I have look all over and have not had any luck. Please let me know if you can help. |
07-10-2009 | | Just because a transformer has a mess of pins, does not mean it has to use all of them. :wink:
AC out of transformer can be rectified by one diode (half-wave) or by two diodes (full wave). It can also be rectified by four diodes (full wave bridge). |
07-10-2009 | | One "set of pins" has 24vac while the other has like 3vac. What is happening is the relays are switching back off after a few mintues. The coil will energize and the oven will get hot but then a few mintues later the relay cuts off? Does that |
07-10-2009 | | what is wrong with it? does it display a raster? any ticking/clicking sounds from within the set
what year was it made in?
viewsonic has made several variations of this model
most common problems with these monitors usually required flyback transform |
