    Re: Vestel 17PW16-2 troubleshooting

    On your picture of IC825 it's hard to see where the tracks are isolated from each other where they go under the IC, (as I think you said the original device wasn't surface mounted). Just make sure there are no shorts between pins, does it test OK on diode test? There is no ground - top pin is anode, middle pin & tab are cathode.

        Sorry, I was merely (uninformed) stating there is continuity in diode mode between the top tab/pin (pin 4) and centre stubby pin 2. The original didn't have a connection and it's easy enough to remove so I might do that. I only typed ground in error.

        Does this new picture help show that the centre pin trace appears to join up with tab?

            Just make sure it reads correctly on diode test, left pin to tab/middle pin (your latest pic). Also that these pins are not shorted to your circuit ground.

                Troubleshooting Vestel TV, has standby, but cannot turn ON
                by Adenitz
                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)...

                Hitachi 32HAE2351 Vestel 17MB171 - Rotate Image
                Mainboard: VESTEL 17MB171 Chassis: VES315WNGB - 2D - N52
                The TV was stuck on the logo and I couldn't access the update menu.
                I couldn't find the firmware for the Hitachi 32HAE2351 and updated it with the Toshiba 32WA2063DG - Vestel 17MB171 firmware.
                The image result was good, but the image is inverted.
                The image rotation/mirror function doesn't exist in the Menu Server. I can't correct the image.
                Do you have the firmware for the Hitachi 32HAE2351 - Vestel 17MB171 motherboard or a solution to rotate the image in...

                Vestel tv, how to flip the image?
                by France_53
                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...

                Schenker VIA 15 PRO, PF 4NU1F V1.0, P/N: MBPPF4NU18-F310 - 36mA in stand-by
                by FriedFred
                Hello, everyone!
                I have here a Schenker VIA 15 PRO, with this numbers on the board: PF 4NU1F V1.0 and P/N: MBPPF4NU18-F310 .
                I took out the memory and the battery and the SSD.

                So, in stand-by, only the board, takes 36mA. No power-button pressed at all, I can measure 1.8V, 3.3V, 5V. All coils present voltages except the two power rails for the CPU. The CPU is a AMD Ryzen 5 4600H.
                After pressing the power-button, the current raises to 500mA and the two power rails for the CPU show up with 0.8V.
                After several seconds, the fans switch-off and the board keeps powered...

                LG OLE65C1 Stand-By issue
                by Titus6
                Hello everyone,

                I bought an OLED65C1 refurbished TV back in 2022 from a shop. The TV is awesome, this is my first OLED and I really love it.

                However I have an issue with the TV since the end of last year. I noticed when my TV is in Stand-By, sometimes the LED goes off then comes back on. When do so it seem periodical. It only goes away for 1-2 seconds, than comes back on. The TV NEVER turnes off, while it's on, so it's not overheating issue or electrical power issue.

                I bought a service remote (MKJ39170828) and checked the menu 3. Power On/Off Status. I took...
