Re: Dell P2417h Vertical lines

This should be panel related problem, not fixable unless u have tab bond machine to change the COF....

Re: Dell P2715Q monitor image issue



Hi there, did u manage to fix the monitor after replacing RT6811 IC on TCON ?...

Re: Dell U3011 no display after a few minutes



Hi there,

My monitor are having this problem as well.
I have tried to solder the capacitor and no luck.
I proceed to order this IC from digikey and manage to solder it in.

Previously the monitor will black out after 5 minute, now the monitor is still rocking after 2 hours!!

Thank you sir for sharing the solution! God bless!...

Re: Dead Dell P2416db - No standby/power LED detected

Please help to disconnect the 10V out of mcp2315. I dont think thats the right voltage and might have potential to damage the board. Possible to trace which circuitry do the mcp2315 connected to? But i think its tough

I guess the more common voltages would be 5v, 3.3v, 1.8v, 1.1v, no idea what we gonna do next, perhaps need other more experience member to comment.

Re: Dead Dell P2416db - No standby/power LED detected

Hi Mattie,

Based on measurement where EN line are getting 1V only.
My hypothesis would be the switching regulator MP2315's voltage divider resistor from VIN to EN are burnt or worn out. If you look at MP2315 datasheet page 16 where they show typical application circuit (Note: can ignore the Vo since we only focus on EN line), EN line would need a resistor divider R6 and R7 from Vin. Assuming our Vin is 19V, R6 is 100kohm and EN line typically need 1.4V, hence R7 would need at least 8kohm.

Hi all, I have a Dell U2413f that has no backlight. Monitor can turn on and off normally without backlight. I will share the troubleshoot steps that I did and provide more information.

Hence first thing that I did was probing the voltages on bareboard (Power board + display board ONLY *not connected to display panel, not sure is it call display board, pls let me know the correct term) and below are the voltages:

Pin Volt (V)
1 0
2 NC [You can see there are no pin exist in the attached photo]
3 0
4 5
5 24
6 24
7 11.8...
