15-01-2011 | | I have pulled the convergence STKs out and turned on the TV with no change in operation. I am certain it is not a convergence problem. Where do I go next? |
15-01-2011 | Hannspree JT01-32E2-000G - Viewsonic N3252W | Some info on PSU repair.
These power supplies suffer from Dried up capacitors on the secondary side of the Power supply, When these go, Mainly the ones for the 5V (CS21,22 = 1500uF 16V and the smaller 220uF CS20) they cause the primary side to become u |

Q7 is MMBT4401LT1G NPN 600mA transistor, although a Switching Transistor it is used as a simple emmitter folower linear regulator! any sot 23 NPN with a rating abo |

15-01-2011 | | I'd confirm that all power supply secondaries are trying to come up and that there is no other heavy loads stopping them. Also regulator failures.
What happens IF you were to keep the relay energized? (either by putting a jumper or your own voltage to dr |

16-01-2011 | Sanyo DP32746 | Hello, I need a Inverter board for A Sanyo DP32746 TV. The Numbers on the board I need to replace read VIT79001.52 REV.5. I found a board to purchase but the Numbers are a little different. They read VIT79001.52 REV:0. Do you know if the REV.O makes the |
16-01-2011 | | There is no set standards on numbering on SMD transistors. While there are several databases available, there is no guarantee that it may be the same transistor you are looking for? For example there is a "625" on zetex/diodes inc--one of severa |
16-01-2011 | | With STKs not installed, the following secondary voltages (in parentheses) I've read as:

Seems a little high, don't it?
?PPD3? - now, or ?PPD5? earlier. Or do you mean both? |
16-01-2011 | Yamaha DVDS795 | I checked
the supply voltages are not present.
Which component on the power supply board is
broken?
Thanks

Which of the following is yours?
U ........ U.S.A. model
G ........ European model
C ........ Canadial model
B ........ United Kingdom model
