    Standby Transformer Troubleshooting.

    How common is it for transformers to fail?

    Re: Standby Transformer Troubleshooting.

    Very, very rare. Exceptions apply for the high voltage inverter transformers, which generally fail due to intra-winding insulation failure (due to the high intra-winding voltages.)

    A work colleague of mine told me that they didn't like to have transformers that bridge the primary-secondary barrier fail, for any reason, because it could compromise the isolation safety of the equipment. There's only a few layers of insulating tape between the copper windings in a transformer. A flash over or arc inside it could burn through that insulation, creating an isolation fault and an electrocution hazard.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

        Hi all!

        HISENSE 65E7KQ PRO
        RSAG7.820.13512 - chassis

        RSAG7.820.12059 - power
        HD650Y3U77 - panel
        KLM8G1GETF - emmc

        The TV does not turn on, the standby indicator is on. All voltages are present.
        Emms is dead. Not readable, not detected.
        Replaced emmc.

        Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
        by tvguy12012012120
        This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

        Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

        Sony STR-DB870QS standby transformer
        by denisten
        Hi everyone, i am a newbie here and i hope i will find the help i need. I have the above mentioned receiver with standby transformer's primary coil damaged. I have searched the net without success to find any tech data about this transformer. I have only the Sony part number1-437-313-11 and TAM Malaysia M0126. I guess i could find replacement for it, but i need to know the secondary coil voltages and VA. It is 220v on the primary. It has 5 pins on the secondary, the outer two are not used and i have 6.5 ohms between pins 2and 4, 3,9 ohms between 2 and 3, and 3,6 ohms between 3 and 4. Can someone...

        DPS285BP 5v standby transformer blown

        Power supply board DPS 285BP Run TKB096WJQZ

        Standby transformer markings (attached picture)
        MP-130I(01)
        AV-DP11153 Delta
        Dcum 1244(03) H6P

        So an event in the primary exploded the cap (C7901)on pin one of the Standby circuit IC. So after replacing a couple diodes a the 2.2ohm resistor(fuse) I found the transformer inputs are open.

        Anyone know about replacements for this transformer?
        I suspect the original is not available.

        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)...
