Getting guidance from your picture, I was able to swing the whole assembly up. Here are the remaining test results on diode scale. R5705 12 ohms (buzzer beeps) R5706 334 ohms D5717 575 ohms (open when tested with prongs switched) Q5706 (1= connected to C5709, 2= connected to R5705, 3= connected to R5706) between 1 and 2 12ohms (buzzer beeps), with switched prongs; 12ohms (buzzer beeps) between 2 and 3 655 ohms, with switched prongs; open between 1 and 3 1980 ohms, with switched prongs; 652 ohms Here are the pictures showing the connector in first picture and my achievement (thanks to you) in other.   |

The ones you have circled in red just pull straight out. Does not even take much effort. Grab the flat white ribbon part and pull it out if the connector.

OK, did you find any more defective components in the light of my recent tests?

That 12 ohm on Q5706, between 1 and 2 has me curious. Is this a SM transistor or does it have legs?

It is a SM (surface mount) type.

Well then, since you have to order some parts, maybe you should order a few of those also and just change it anyways. The resistor values seem ok and the diode also seems ok.

Just to recap, we have 3 defective items Q5705, P5003 and Q5706. I have IDs of Q5705 (D1763A) and P5003 (Pico type 1A rating) but I do not have ID for Q5706, would you be able to look for it.
I will be sourcing these components from local vancouver market, I may succeed or not. In case I can not get these parts locally, is there any other source that you would kindly suggest.
I am so glad that troubleshooting is done successfully, and am very very thankful to you.

Ha, not to disappoint but your never done (even troubleshooting) until it is back together and working, lol.
P5003 = 1amp pico
Q5705 = 2SD1763A
Q5706 = 2SC3906K
I would get a few of each since you don't know for sure yet if something else took out these parts. If you cannot get them from your source let me know and I will check mine.

One of my suppliers has the parts in stock but you cannot order from them. I will have to attached the parts to my order and then send them to you after I receiver them. You end up with 2 shipping charges but the prices are cheap enough it really doesn't matter. Plus, how else would you get them, lol.
So I just need to know how many of each number you want. Here are the prices so you can decide.
2SC3906= .58
2SD1763A= 3.36
Pico 1 amp= .45

You suggest the quantity, I guess 3 each should be enough, but if you recommend more I will be ok. I can pay through paypal if it suites you.

You need to go back and check the VH+ and VH-.  |
