24-01-2012 | Fluke 6061A, Need Help | I also have a 6061A that has 3 amplitude ranges which have broken down, and in a search for the service manual I found schematics for the 6060B (equivalent older model) after doing a google search. Here is one such place: 128.238.9.201/~kurt/manuals/manua |
25-01-2012 | | My bad. Downloaded service lit. from ET, and sure enough ... only two sockets / bulbs.
Have you resoldered ALL transformer joints mentioned earlier? |
25-01-2012 | Westinghouse LD-3235 | I have a Westinghouse LD-3235 that turns on but the back light does not turn on . If you shine a light on the screen you can see a picture. Anyone know what to look for it is a led TV.
Thanks |
25-01-2012 | bad trnsfotmer? | I will do the resolder as soon as possible . but I checked the output voltage of it, also compering to BLT_ON voltage :
checking the transform T601 onboard (not connecting to power), I could see that terminal 1,2,3,4,5 are all shortcut between each oth |
25-01-2012 | ueser & service manual wanted | Hi .Iam looking for a instruction manual and service manual for a Ferguson TX 22G2.
Also a service manual for a 51A3. |
25-01-2012 | Wanted | Front screen clips for a Ferguson 22G2.They hold inplace the plate glass in front of the tv. |

25-01-2012 | | Let's try for the "DC" voltage readings on the power supply diode cathodes.
D701 (pin 2) ground to C703/C704 "negative" terminal (approximately {~}13VDC);
D702 cathode ground to C703/C704 "negative" terminal (~3.3VDC);

25-01-2012 | | D701 (pin 2) ground to C703/C704 "negative" terminal:
1) 12.67VDC at starting -(BLT_ON 13.4v & backlight turn on) ,
2) 13.72 when connected to VGA source,
3) 14.45VDC "normaly"
D702 cathode ground to C703/C704 "neg |
25-01-2012 | Rattle in sub and maybe a bird | Just wanted to share this with any IL60 owners. I had a intermittent rattle in my right tower sub. I took the woofer out and could hear something rattling behind the dust cap. I was going to remove the dust cap, but couldn't cut the "super glue" |
25-01-2012 | | Let's try that again.
Red DVM lead (DVM set to DCV) connected to D701 (pin #2), Black DVM lead connected to ground at C703/C704 "negative" terminal (you should get approximately {~}13VDC ALL Time - whether the set is only plugged in, irregard |

25-01-2012 | | [quote:9c1e6dff74="tofutofu"]OK, the voltage is changing between D701 (pin #2) TO C703 "negative" and going "crazy" when connecting/starting/normal..
(by the way, isn't it the same as the voltage between C703 positive & negative |
25-01-2012 | | I just found out that the V-INVERTER is stable 14v when not connected to signal (VGA)
BUT when connected to signal (VGA) the V-INVERTER is moving up & down from 13.5V to 12V at frequency that might be same to the LCD blinking (hard to know exactly... |
25-01-2012 | | [b:ad8fbf36cb]"Float" either end of L701"[/b:ad8fbf36cb] ??
do you mean connecting between the 2 ends with some wire? |
25-01-2012 | | I mean unsolder one end or the other and letting it float not touching anything while remeasuring at common of Diode. |
26-01-2012 | | OK :wink:
unsolding one "leg" of L701, gave 18.5V between common of Diode (C703 positive) and ground (C703 negative). |
26-01-2012 | | by the way, C701 & C707 are 2 cap's I replaced as thay looked "puffed" |

Stayed steady regardless of signal or set being turned on/off?
C70 |
26-01-2012 | | your right about C701, that looks OK , I ment C707.. :oops:
19.6v when no signal
~18.5v when off (not steady)
19.4v-19.6v when on/start {going slowly up} (with signal) |

26-01-2012 | | C707 is/was one ... C701 is NOT the other ... That leaves C___ as the 2nd?
The solder connections on the two transformers mentioned earlier are infamous for developing "rings" around one or more pins. As are some of the smaller transistors on |
