Re: T240 inverter and resistor get hot again
Just an update, TV still works fine with the old board and it does not get so heat anymore
I still have the new board which is different because the seller don´t want it back but refund me the money, respect for this solution.
I think to keep it as it is with the original old board
What is your advice ?

Re: T240 inverter and resistor get hot again
Since I order the new board I had the old board connected but I did not close the backside cover so it is open on the backside and it works fine and the smell is almost gone.
Inverter and resistor still get hot
Now I connect the new but different board and same problem came on, after ±2 seconds backlight goes off.
So I think the new different board does not work properly in my Samsung T240 and I contact the seller about it and I connect the old board again and again it work wellLeave a comment:

Thank you
I try it and let it know.

Re: T240 inverter and resistor get hot again
I just receive the new board but even it is the same type (IP-54155A) it is differend and my question is can I use this board ?
I see them a lot for the Samsung T240 but I am not sure if it will work properly...Leave a comment:

Re: T240 inverter and resistor get hot again
Yes I know but I have to take that chance and if it happen again I have to change the CCFL´s too.
I have not check where to buy them but I believe they are not that expensiveLeave a comment:

Re: T240 inverter and resistor get hot again
OK thanks again.
I think it could be too many thinks that heat-up the resistor and inverter even I think that the inverter will be extra warm when the CCFL´s are on but the resistor should be some kind of cold
This took me a week now to find out what is the problem and I have to make a decision.
I think I take the change to order a new board so that I know that the board is OK and keep an eye on the resistor and inverter.
Thank you all so far and I come back to youLeave a comment:

Re: T240 inverter and resistor get hot again
Thanks a lot, I don´t know if it depends which inverter (T301) is on-board ?
I have the TM10160Leave a comment:

Re: T240 inverter and resistor get hot again
Maybe a wrong resistor
I measure the bad resistor as a 390K but after comparing 2 pictures it could be a 190K.
Maybe you can take a look ?...Leave a comment:

Re: T240 inverter and resistor get hot again
I turn down the brightness but that did not solve the heating, resistor and inverter still getting hot.
In the first time I solder the resistor in a higher position but that did not solve the heating problem.
Even that, I have not so much space so I could not get it higher then ±3mm otherwise the steel cover put it down.
My most important question is : is it not the lamps that take to much power ?
If that is not the problem then I can buy a new boardLeave a comment:

Re: T240 inverter and resistor get hot again
I check all resistors because there not so much
R101 = 35,8K
R103 = 4,5
R104 - 28,2
R105 = 72,3
F301 = 4,3
I don´t have tools to check caps but they look good
This is my board...Leave a comment:

T240 inverter and resistor get hot again
Hi, my T240 had the well know 2 seconds problem and I change the inverter.
But when I open the monitor I saw that the R301 has been very hot, it was burned under the resistor so I change that too and replaced by a 390K-5W resistor.
It has been so hot that even the trail at the backside came loose
Monitor works again and keep working for 2 days now but I smell something so open the monitor again and both inverter and resistor get very hot again.
Because they are very close to eachother I think it is the resistor that smell
