Re: Vestel BL-On/Off how to
normally you would jump ps/on to 5v and bl/on to 5v, (pending make and so forth) with 1k resister.
ps/on turns on your other voltages and bl/on is the on command for the backlights.WHY CAN'T PHILIPS USE PHILLIPS HEAD SCREWS?Comment

Re: Vestel BL-On/Off how to
+1
If the schematic for 17IPS12-R3 is similar to your power supply then jumper ST_BY to +5V_STBY and also BL_ON-OFF to +5V_STBY

Re: Vestel BL-On/Off how to
That would be brilliant. There is a thread at the top of page 1 for EEPROM dumps.
It would be excellent if the mainboard model number, IC location and part number along with screen model number was given along with the dump file.
I'm sure the forum users would be very pleased with anything you could offerWilling to help but I'm no expert.Comment

Re: Vestel BL-On/Off how to
the more eeprom dumps the better.
also having your user name in the eeprom thread will make it easier to ask if you have access to a particular eeprom.
thanks heaps.WHY CAN'T PHILIPS USE PHILLIPS HEAD SCREWS?Comment

Hello!
I am in despair with a Vestel 17IPS12 power supply.
With the TV, the backlight just stays off.
( Backlight tested with backlight tester = IO)
12V on the secondary side are there and constant. Voltage of the backlight is when switching on once briefly at about 60-70V and then drops slowly. (up to about 36V I have observed it whether it then drops further I do not know).
But I am sure that the problem is on the primary side, because the DC high voltage is only at 295V. I expected about 330V (with an input of 230V 50Hz).
I checked the mosfet in the component... -
Hi

Any help appreciated!... -
Hello everyone from Italy, I'm here to ask for help on a Vestel TV, I've had a Vestel TV branded "XD" with a broken screen for years, but now I've found a Telefunken (still Vestel but older) and I've mounted the panel on the "XD" TV, it works, but the screen is upside down, given that Vestel does not allow you to rotate the image from the service menu, does anyone know how to solve the problem? the original panel is marked ves315WNDS-2D-N12 while the main board 17mb110, the panel I mounted instead in the tv (from the telefunken) is a ves315WNDA-02. ... It is not worth repairing... -

Hello,
I need advice in troubleshooting Telefunken TV (it is actually Vestel). There is red Standby light but TV cannot be turned on either by remote control (which is good and tested on another TV) or by actual on/off switch at the back of the TV.
Power board is Vestel 17IPS71 and I'm not sure about the mainboard, it seems like 17MB82S
Both boards are shown in the attached photos.
What is normally first that is checked in this case. I have removed power board, make sure it has no dangerous voltage on the big caps and check many components (transistors and diodes)...
