    TV Question:: has ANYONE here...EVER seen a hot-chassis FLAT-PANEL tv?

    I am just curious--for those of us who still work on tv sets... has ANYONE here ever seen a flat-panel of ANY type...that used a HOT chassis--like many CRT sets used to do...until it became inconvenient to do so...because of all of the A/V I/O and such..

    I know I have worked on many flat panel sets of all types...and i have NEVER seen a hot one. I think EVERY one of them had an SMPS of some sort...some were an "external "brick" type--but still an smps cold supply...

      If the power supply was HOT, ALL inputs would need to be isolated, also that includes any metal the customer can come in contact with (ie cabinet)
      If an old crt tv had a hot chassis the R.F. input and any video/audio jack was isolated, (old tv's with a rotary tuners had the shaft isolated from where the knob connected and the other controls had plastic shafts)

          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....

          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...

          Mackie Th15 SMPS low Vout
          by madan1
          Hello,
          I'm troubleshooting a PA speaker Mackie Th15 (schematics attached).
          It is basically a smps with amp and some dsp.
          The issue is that on the secondary side I read +/- ~23V instead of the expected +/- 38V. Indeed all secondary side and feedback/aux rails are like 1/2-3/5 of the expected values.
          Q2, Q3, C35, C40, C33, C36, C41 and C42 were tested out of circuit with a component tester and read fine. Most of the other components on the primary were tested in circuit and seem to be fine. +HV to -HV on primary is ~330V.
          By the way, the ferrite core of L10 is broken,...

          Replacement for the Siemens Bakelite caps in an early 1980s SMPS
          by rewease
          Hi everyone,

          There actually was a time when early SMPS and late bakelite housed electrolytic caps coexisted in high end industrial gear. A friend of mine just got himself a CNC milling machine form that time with its first set of now 41 year old caps still installed in the PSU... and it's malfunctioning.

          Two of the caps have already leaked slightly onto the board. I have not desoldered or measured any so far but they should qualify for replacement.

          Now I'm wondering what to put in there as a replacement. First idea was state of the art low-ESR Nippon KY,...
