Re: Harman / JBL Xtreme2 Bluetooth speaker
Thanks a lot my dear friend!!!! Once I get back home I'll search for a compatible in my donor pile and get back with the results! Can't thank you enough.
See you in a bit.

Harman / JBL Xtreme2 Bluetooth speaker
Hi guys. Sorry if I'm posting this in the wrong place.
So here's the thing. A friend gave this device saying it had no sign of life. After opening it, I found a burned soc23-6 which I cannot identify. I've searched for schematics for this model with no avail. Perhaps someone with more knowledge can assume what it is.
Main board pn is T651000008730. I'll attach every picture o took out just to help in any way possible.
Power input for this device is 19v.
Thanks a lot.... -

Re: Blaupunkt B32A122T - no power
The diode on the left, next to the inverter plug, shows continuity both ways, as its twin neighbor reads normal. did i struck oil?
Since theyre working in paralell, for testing purpose, it should work with the shorted on pulled out right? or should i replace before testing?...Leave a comment:

Re: Blaupunkt B32A122T - no power
I tested the mosfet with the multimeter.. the basic open close / charge discharge test.
RB148 reads 0.4Ohm
Mosfet is MDF7N60B
When taking the pics for you, i found RB108 to be "funny looking" so i measured it to 8.7kohm (onboard). Should read 22 Ohm am i right??
Thanks for all your time once again!...Leave a comment:

Re: Blaupunkt B32A122T - no power
Sorry for being so long.
Tested every test point and the results are the same. 0 everywhere with the exception of the spikes every 2 seconds... as if the system is trying to come up, but something is shutting it off....Leave a comment:

Re: Blaupunkt B32A122T - no power
If i keep the probe at pin 8... mostly 0, then every 2 seconds or so i get a spike to almost 1v, but instant drop to 0 again.Leave a comment:

Re: Blaupunkt B32A122T - no power

Blaupunkt B32A122T - no power
Hi everyone.
I have the above mentioned set for repair, and can find any of the power rails.
Being a beginner, i could use a hand pointing to where i should start looking.
Searched the web for a schematic, but didnt find one... aparently, there's a bunch of different boards with this number on them.
Thanks in advance for yout time.
Only thing i tested was the mosfet under the heatsink with the multimeter for shorts and on/off operation.

Re: Sony Bravia KDL-32BX400 Solid Green Power Light, nothing else!
The power reset was a no go.. The tv was sitting for a week by the customers front door before they brought it to me...
Anyways... First thing i did was pop off the power supply, remove and reset all mosfets with fresh solder, as well as the hi power capacitor. Result, no dice.
One thing was troubling me... when measuring the input fuse on the tcon board, the voltage was always near 0... but if i wiggled the connector it would vary a bit... never to 12, but up and down, so power down...Leave a comment:

Sony Bravia KDL-32BX400 Solid Green Power Light, nothing else!
Hi everyone!
Could really use some of your knowledge with some pointers to where i should start looking at.
So, as soon as i plug the mains, i get the green power light. no blinks no nothing. solid green. trying to put it in stand by is a no go... completely unresponsive, both in button panel as in remote.
Seeing im very new to this, could some one try and help me fix the darn thing?
Thanks a lot. Didnt find any schematics for it....
