SMD caps 103 replacement

[Cryogen]

Hello

I have 2 blown smd capacitors on my Sony 3d t-con board.

On the top the label says 103.

Do you know which Voltage and current are they rated?

Can we see the pictures? 103 printed on top sounds like 10K resistor not cap, but we cannot tell until we see the pictures.

They're not capacitors if they have something written on top, usually resistors have the value written on them. 103 would be short for 10 and 3 zeroes after, so 10 000 or 10 kohm.

Are you sure they're capacitors? Any writing on the PCB around the parts? Maybe get a picture of the board.

Sorry guys, I said caps , they are SMD FUSES!

Re: SMD caps 103 replacement

These look the same. What do you think?

These

or the panasonic ones?

Again, upload the pictures.
From the link you provided, this is the description "200 x SMD SMT 1206 Chip Resistors Surface Mount 10K 10Kohm ohms 103 +/-5% RoHs"

"Sorry guys, I said caps , they are SMD FUSES!" why do you think it is a fuse? It is not fuse either. for 10K to burn up, there is not enough Voltage on the T-CON board to force enough current through 10K resistor to be damaged.
Second link:
"50 X PANASONIC, ERJ2GEJ103X, RESISTOR, 10K, 100MW, 5%"
Why do you think it is bad?

I think they are bad because there is a short. I even heard the zapping noise when I plugged the ribbon cable wrongly in the T-con.

Re: SMD caps 103 replacement

If you think you are are testing the fuse, if the fuse is good then it will show up with <1 Ohms in resistance (showing as shorted circuit).
So what resistance reading do you get on this 103 device? If it shows as <1 Ohms then you need to see first if there is another device connected in parallel with this resistor that may be shorted, then you can remove the suspected bad part then take the resistance reading between those two empty pads where the suspected bad part was soldered to to see if it still show <1 Ohms or not.
Is this the same T-CON you started?

Starting a new thread is not going to help solve the problem when the old thread was not followed-up on.
Starting a new thread will just make the helpers frustrated after giving all the instructions and no follow through by the OP.

BTW, the silkscreen shows it as IC50xx so that does not look to be Transistor, the silkscreen for Transistor on that board is shown as Qxx.
Are the traces from the caps connected to that IC directly?
Aye, it looks like they are on the same trace."

No , it is not that one. I would have not started another thread otherwise.
I will post a pic asap, my phone does now have enough memory.
