This is for a rechargeable battery pack that needs to be rebuilt.
I cannot find a replacement for one of the components. See pic attached -- the markings are:
KLIXON 6MM06-AA03
I am trying to locate the datasheet for it so I can test the old one, or find another one with similar characteristics.
Thank you in advance for any help....

Re: Blink EVSE touchscreen intermittent problem.
I saw those pages but various things threw me off.
If the touchpad surface is covered with a plastic cover (whose traces around the underside edge get powered from 2 of the 4 lines), could it still be capacitive? I didn't see any explicit mention of this, but with capacitive it seems to me that all the lines would be going to the glass layer.
The other two lines connect to the traces all around the upper surface of the glass. That plastic cover provides an ever so slight airgap, so there is a slight "give"... -
Re: Blink EVSE touchscreen intermittent problem.
I was more inclined to think it is resistive, but I can't find a way to identify the existing one. The user interface running on the display seems to rely on a single-touch at a time, so my guess is it is resistive.
I've googled a lot, and found various suppliers for touchscreen overlays for under $30, which will solve the problem I am having, but I need to know what kind mine is. I found the whole assembly on Aliexpress but the description doesn't state if the touchscreen digitizer is cap. or res....Leave a comment:

Re: Mean Well PT-65-R13VAI with a short.
for the sake of learning, is there a relationship between wattage of the DBT, and the rating of the PSU? If say a PSU with 240VAC input was rated at 65W (full load), what would be an appropriate wattage for the each of the two 120VAC incand. bulbs?Leave a comment:

Re: Mean Well PT-65-R13VAI with a short.
I ordered a replacement board.
I already tried another fuse. Can I use a 120v DBT on a 240v circuit? The PSU is rated at 65 watts.Leave a comment:

Re: Mean Well PT-65-R13VAI with a short.
Thank you for this link. Can you go over my logic to confirm the board I need to order?
The PS board has the following marking: PT-65-R13VAI. The data sheet doesn't list that exact one.
The PS output header has pins labelled -V, GND, +5V, +V
A couple of boards later, I found that the +V goes into a small linux board, which has a 3-pin power input, labelled GND, +15V, and +5V. I checked continuity on all pins, and it seems the +15V labelled pin is fed from the +V on the PS output....Leave a comment:

Mean Well PT-65-R13VAI with a short.
This looks to be the product page of the unit I am working with:
[url]https://www.meanwell.com/webapp/product/search.aspx?prod=PT-65[/url]
The PS was working until an accidental short caused a white puff of smoke and the fuse to blow. An uninsulated ground mains wire was pushed under the right edge of the board (all along the edge of RTH1, C36, C16, ... SHR1).
The device supplies 240V input to the PS board, and the fuse is 250V/4A.
How do I isolate what blew? Nothing looks burned.https://This looks to be the product... working with:... -
Blink EVSE touchscreen intermittent problem.
This is a blink Level 2 EVSE and it has an issue with the touch-screen. It was installed outdoors and facing the sun for extended periods. I cleaned the touchscreen assembly including the edges.
There are no display issues, but the touchscreen is very finicky, and barely works intermittently. On power-up the EVSE goes through a touchscreen calibration procedure: touch 5 X's (corners + center), followed by 5 O's in the same screen positions. It doesn't accept touches after the 3rd-7th calibration point. The calibration period has a countdown, and then restarts. One time I touched... -

I cleaned the LVDS cable and connectors with alcohol and sure enough the picture is back to normal again.
A big thank you to all who helped.Leave a comment:

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
I checked LVDS cable ends, and their connectors. They all look good. Tomorrow I'll try cleaning everything with alcohol, and reseating.
I checked all the voltages on the new T-CON board -- here are some relevant ones:
[CODE]
VIN 12.48
AVDD 17.10
VCC12 1.22
VCC33 3.27
VOFFE -13.33
VSS -7.45
VONE 28.00
VR 8.45
VCOMS1 6.92
VCOMS2 6.84
VCOMS3 6.92
VCOMS4 6.92
VCOMG1 6.84
VCOMG2L 7.04

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
Update:
I replaced the T-CON with a used one of unknown condition, and it now has a picture, but it is distorted. Sound is OK, antenna and all HDMI ports work but picture is distorted on all input sources. I did a service mode factory reset. The distortion constantly shifts around and is not specific to any part of the screen....Last edited by GLInick; 02-21-2019, 11:28 AM.Leave a comment:

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
ICD2 Pin 1 is 0
ICD2 Pin 2 is 0
ICD2 Pin 3 is 12.64
ICD2 Pin 4 is 12.64
ICD2 Pin 5 is 0
ICD2 Pin 6 is 0
Is this the data sheet for ICD2?

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
ICD2 is 58AD, and after startup, the pins below and above the 'D' (pins 3, 4?) are 12.64 volts.
I didn't take any startup voltages.
I didn't report that before, but touching GATE to take a voltage reading while the TV is on causes it to shut off. If I probe that pin and then turn on the TV, it will stay on and shows 12.64V. Is this due to my cheap DMM adding resistance to the circuit?
Also, there are no pins labelled L6, and D6 on the 17122....Last edited by GLInick; 02-15-2019, 06:14 PM.Leave a comment:

Can I apply 15V from an external supply to the AVDD test point on the defective board?Leave a comment:

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
Thank you for the link.
I cross-referenced with shopjimmy it is a listed substitute part # and ordered it.
Should be here next week. I'll report back with results.
EDIT: thank you to everyone for your help. I am learning a lot....Last edited by GLInick; 02-14-2019, 11:47 AM.Leave a comment:

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
And would it make sense to try to apply 15V (and gradually up to 20V) from an external source to see if that does anything? I'd rather not risk more damage to the board.Last edited by GLInick; 02-13-2019, 05:46 PM.Leave a comment:

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
So, I've traced all components attached to each pin on ICD1/MAX17122, measured the resistance of every cap and resistor, and then voltages. All caps directly connected to a chip pin were in the 500-750 Ohm range.
I can type all the measurements up, but here is the jest of it:
[CODE]
[B]PIN NAME MEASURED[/B]
2 IN 12.65V
3,4 IN2 12.65V
6,7 LX2 2.45 - 2.6V
23 DEL 3.8 - 4.8V
30 LX3 0V
31 IN3 12.65V
35 VL 5v
37,38 LX1...Last edited by GLInick; 02-13-2019, 05:06 PM.Leave a comment:

Re: Samsung UN46C6400RFXZA audio but no picture (pics incl).
Thank you, I was just googling for that.
Does this rule out that something else is not going on in the other two boards?
Should I replace ICD1, or is there any other testing I should do?Leave a comment:

Just to be clear, all of the measurements I posted above were taken with everything connected, so both of the ribbon cables from the LCD were in circuit....Leave a comment:
