Need assistance in getting details of part number for power mixer


I tried to post a possible solution and it may have not made it so I will try again.

Download the data sheet for an LM3886.

This chip is used in a lot of linear audio amps in the 50 Watt range.

Download the data sheet and then check if connections on your unit make sense.

Smaller units sometimes use the TDA2050 7 lead TO220 style chip so look at that one in the LM3886 isn't the one.

I need data sheet of the internal workings of 12" MEADE LX 200 (SCHEMATIC, REPAIR MANUAL, PARTS LIST)


Go to the LX200 Yahoo Group. They have diagrams in the files which you can access if you are a member of the group.

Meade has manuals on their web site here:

Same problem. red light flashes 3 times, but will not turn on.


Hi,

The blinking light means the controller QA01 in the AV_TERM system board is booting and driving the TIMER/REC RED LED light accordingly. This failure mode is true for many conditions, not exclusively for the main PS board PE0071. It could be caused by many things, LOW B, SEINE, AV_TERM, LCD, PROTECT, etc.

Specifically for PE0071+12VDC circuit failure, which is the most common , listen for the LINE relays SR80, SR81 coming online. If several (3) or more clicks are present when applying power to the TV set then suspect the +12, 20, +32 VDC inverter is faulty.

As a quick check, you can disconnect P807B. If the relays cycle every 1-2 seconds then is most definitely the +12VDC inverter. Check for voltage level at optocoupler Q881 pin 4 and this should not be cycling. This point is the VCC for the oscillator. Repair or replace board 75002913 as necessary.

TROUBLESHOOTING: (this is my own, not the OEM !, try at your own risk!)

  1. Check for LINE1 input voltage level at inverter on sheet [4].
  2. Check for LINE2 input voltage level at inverter on sheet [3].
  3. Check for STBY +5VDC & +25 VDC ( observe correct GND REF) page [4]of PE0071 POWER
  4. Check for +22 VDC out of regulator on page [3] out of Q822 Emitter
  5. Check P809B connector for :
  • P809B (12) POWER = 3.00 VDC (+/-0.2)
  • P809B (11) POWER_SIG = 0.00 VDC (HIGH to Power on TV)
  • P809B (10) PROTECT = 0.00 VDC
  • P809B (9) ACDETECT = 3.00 VDC (+/-0.2)
  1. Check for PFC_OUT = 368-371 VDC
  2. Check for +12, +20 & +32 VDC inverter page [5] of schematic manual.

For +12 VDC Inverter, suspect components:

Q880 STR-W6765 PSR (works really hot!!)
C888-C890
D884A and related switching circuit components.

Good luck,

Copying data from one sheet to another if two fileds match


Nope, sorry, although I am truly an expert at Excel formulas, I do not understand what you are trying to end up with in the final cell. We can compare a specified field with two spreadsheets - use named ranges and index/match lookup formulas. But then where you really lose me is in reading "a generic field" to find a match, and then placing what "data from another field" into what "other sheet" - ? See the confusion?

Best way to compare 2 given parameters would be to use a nested if formula, with index/match combo. Here is a simple Excel example of how such a formula could be structured:

Sample Data (columnar arangement):
A1: Part B1: Code C1: Price D1: Find Part E1: Find Code
A2: x B2: 11 C2: 5.00 D2: y E2: 12
A3: x B3: 12 C3: 6.00 D3: y E3: 11
A4: y B4: 11 C4: 7.00 D4: x E4: 12
A5: y B5: 12 C5: 8.00 D5: x E5: 11

To retrieve the price for part y with code 12 and return the value to cell F2, type the following formula in cell F2:
=INDEX($C$2:$C$5,MATCH(D2,IF($B$2:$B$5=E2,$A$2:$A$5),0))

Press CTRL+SHIFT+ENTER to enter the formula as an array formula. The formula returns the value 8.00.

To take this one step further, with range names, this example will find one value at a specified location which matches a specific row header value and column header value. Let's say the range is home values (Range=HomeVal), Column A of HomeVal contains street addresses,"row headers" (Range=StAddress), and Row 1 contains dates of the various values that are in the body of the table, "column headers" (Range=Dates). To return the specific value from the range HomeVal to another sheet, where A1=address specified and A2=date specified:
=INDEX(HomeVal,(MATCH($A$1,StAddress,0)),(MATCH($A$2,Dates,0)))

Then make sure to press CTRL+SHIFT+ENTER to enter the formula as an array formula - if you only hit enter, these types of formulas will not work properly.

Please post back if you need further help, with more details, otherwise thank you for using and rating FixYa!
