Trying to put in kit to fix my sc board must have put in D618 backwards. Upon testing popped R601 and R609. Anyone know the values direction if it matters so in can rrplace and see if it still works.

Re: Tnpa5101 help
That number comes up as a C3 buffer board. Check your number again,and list the model number of the tv it came out of. -
Re: Tnpa5101 help
TC-P50S2 is the tvComment

Re: Tnpa5101 help
I don't have the values but directional doesn't matter with these resistors.Did I leave the soldering iron on?Comment

Re: Tnpa5101 help
there's a parts board on eBay for 21 shipped, or there's a new board from China for 85 shipped don't know what one to do. What if I messed up more than I thought on the repair board.Comment

Re: Tnpa5101 help
found a service manual and values of them both now a good place to buy. Looked on digi-key but didn't find any.Attached FilesComment

Ok I screwed up big time and hoping I can fix. I will break down what happened and the images.- Have Dell PowerEdge R730
- Bought Tesla P40
- Researched power cables and order correct one, pic had two black connectors in photos
- Power cable arrived, same connectors (EPS-12v) on both ends
Both sides are the same plug but different colors. The listing stated that colors would be random. OK I plug it in, red side to riser board, black side to GPU. - Power on.
- System immediately turns off.
- I only had 1 PSU plugged in and it was blinking orange, I thought I drew too much so I plugged in

Hello, I have got a recuperator that is not working, the problem is in the pcb but I can not really determine in which part exactly.
I have an exact second one and these are the differences I found:
1.
Bad PCB's:
2 Triacs BTS136 read 0.245 across the diode junctions.
Good PCB's triacs read 0.588.
I did measure in circuit
The JST16A triac reads the same in both pcbs.
2.
Resistor which I marked as R1
Bad PCB's - 1.4kOhm
Good PCB's - 4.5kOhm
Could it have fried something because of that and how did the resistance... -
Owner replaced the battery, but plugged in with backwards polarity. From AC works great, akku seems to be dead. I replaced the battery, powered on from battery, works for some minutes, then boom, shooted off. The another (used) battery seems to be dead too. Charging voltage 3-4V, Before PQ4403 10V. Shottky and the caps measured ok. After a while of "charging" led flashing white. Could be only the batteries? -
Hi there,
It is sunday and I got a faulty hp pavilion 15-cs1006na. No available schematics on the entire world. It flashed 5 long 4 short and no post then I discovered the usb 2.0 2. pin in one of the usb-a socket bent backwards and been shorted to 2. and 3. pin of the 3.0. after removing this short in the port the laptop came alive.
Now the laptop freezing randomly. The webcam, the built in mic and according to the device manager one more thing not working which are connected to usb. If I connect anything what have usb 2.0 plug that wont work if i plug anything what... -
I'm about to take a journey into repairing this 3 Channel ICE amp. It's got a bunch of fun components I am not familiar with like Direct Stream Digital chips. It also has some onboard Digital Signal Processor which I haven't identified yet.
I am not familiar with ICE amp circuits other than they are a type of PWM amplifier so I'm assuming they require a ton of high frequency filtering on the output. I'm also assuming that the output of the DSD chips probably directly feed the ICE amp signal since DSD is also essentially PWM or creating an averaged AC signal using high frequency ~2MHz...
