Re: JVC LT-40DJ51J - Vestel 17IPS20 - LEDs very dim
17IPS20 with resistor at J60, some of the boards have nothing at J60, some have only a 2 pin plug at CN500Attached FilesLast edited by R_J; 09-14-2018, 12:21 PM.Comment

Same issue with same PSU. I still can't figure out the main cause of the low voltage.I have other two working spares PSU were backlight rise until 140v and stays stable. On the faulty one the voltage measured on the connector cn 500 with led connected, rise till around 114v than fall down to 107v remaning stable but never reaches the 140v needed to light up the leds...
Any hint?Comment

Hi there !
I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...10-08-2024, 11:58 AM -
Hoping someone has troden this path before !
I'm looking at a JVC LT-39c790 - a vestel based unit.
So, the remote turns it on, led's light up but no picture at all.
I have a spare mainboard, so I know its not that. The PSU seems ok too.
On the AUO T-Con I've got 16v on HAVDD_H but nothing on HAVDD_L - which I'm assuming should also be 16v ?
So, Ive resorted to testing eveything I can on the board as I can't find any schemas for it (AUO 39T15 C04 Ctrl Bd) and I think I've found a diode gone short. it marked D005 on the board and E1 on the package... -
Quick Question Please.
Is low resistance on gate pin 5 of U202 normal? I have a very very low resistance of 5 ohm on this gate. In diode mode, it looks shorted and beeps. Is this a normal behavior of this FAN6300 IC?
All other components on this vestel board have valid readings except for this U202 IC. -
Hi I am having an issue with the LED backlight of this TV. I can see the picture with a flash light, so I determined it was a backlight issue.
Initially, after opening it I found 2 shorted and 1 open LED on 2 strips (total of 4). I removed the LEDs and shorted the pads together to verify if the backlight would work.
Testing it, I found the backlight turned on and I measured 54V when TV was in standby (off), and 100v when TV was turned on. The 4 strips each contain 9 LEDs, so 36 in all minus 3.
Instead of putting it back together I decided to replace... -
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...
