    KOGAN KALEWD39SMTWA failure to launch

    Just thought I'd get a few opinions about typical causes of this fault scenario.
    These Chinese re-badged TVs have reduced the componentry down to an absolute minimum. There a small-ish SMPS, the smallest mainboard I've ever seen, and I assume tucked away somewhere but not immediately visible is a T-Con board.
    Symptoms are: Start up from cold, all OK. Switch off into Stand-by with the remote, and sometimes it won't come out of stand-by. The LED indicator goes green, but no backlights or life as such. I'm told that sometimes it will come up with sound but no image (I've not witnessed this). Also reported that sometimes will sit there for awhile in 'green LED' state, but will eventually come to life. De-power at the mains and it will re-start OK.
    It uses CapXon electros on the SMPS.
    Thoughts anyone?

    HISENSE 65E7KQ PRO - no boot

    Hi all!

    HISENSE 65E7KQ PRO
    RSAG7.820.13512 - chassis
    MT9618BAATAB - cpu
    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.
    But with another dump there is no launch

    Onkyo DX-V500 Laser Disc Player - weird SMPS fault
    by dkneyle
    This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.

    Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...

    Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
    by shamsudeen
    Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
    I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

    i know that in linear power supply the noise will be very low comparing to SMPS supply....

    TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
    by howardc64
    All left and right refers to looking from rear of TV (or looking from front with TV upside down)
    • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
    • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

    Huntkey HK340-72FP SMPS shut on load above 2 amps
    by abhishekkumar1902
    I have this Huntkey HK340-72FP PC SMPS where I am facing a strange problem where the SMPS shuts down when the load on any of its 12v output rails goes above 2 amps while the rating of each 12v rail is above 10amps capable.

    I have checked the following:
    1. All output caps are OK, and all output rails read correct voltages at no load
    2. All output diodes are OK
    3. NTC is ok
    4. Hi voltage cap on input correctly reads 150uF on LCR meter per the spec, also the bridge rectifier is OK
    5. No short in main switching MOSFET
    6. All other components...
