Where can I get the manual for MODEL : veco13DB input 12VDC output 12 VDC,400 A Instant 5

English only on Fixya please.

My emerson lc320em3f only gives 8vdc at the 12vdc source
The 12vdc do not rise from 8vdc


Power supply faulty.

output = 12Vdc 0.5A (500mA)

Hi John,

Page 5 of the manual for this radio specifies a 13.8 VDC (12VDC car / truck electrical system) power supply to power the radio.

Connecting to a 24 VDC system will damage the radio and likely require expensive repair or replacement.

Good luck!

you can use just about any wall charger. like a house phone charger or a roaid charger. but look at the INPUT on your jump it should be 12 VDC and fine one that is 12VDC OUTPUT and that it.

I hope i could help you

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,

No. It is not recommended to use this power supply, since it outputs only 12 watts of power, whereas the required power to run your speakers is 26 watts.
You will have to use a power supply which outputs 13 VDC, with at least 2A.

Go to Vector's web site to get your manual

Relays are the first big clue, triggered by the 5 & 12v supply you should be able to trace back using a dmm and see if you have both of those voltages present... The lead coming from the smps to the y-sus board is a good start. On a Vizio I believe the voltages are listed per pin right on the board...
If you had any kind of relay sound then you could suspect the y-sustain or z-sustain board or something else. With the relays being silent I'd strongly suspect the power supply.
