    Dear Mr. Yong,

    Today, my 16yrs. old SAMSUNG PLANO Television got suddenly switched off and sinnce then it's prehaps turning inside as I hear a little sound of power on but nothing is coming on the screen and no power light is glowing at all ?

    Meanwhile, the Samsung Plano television got suddenly switch off and automatically on. But after that it never turned on what I wrote above?

    Awaiting for the solution ?

      Hi Amitava,

      It can be due to dry joints or bad e-caps. The best is to check if the power supply is giving out output voltages or not.

      First discharge the power supply condenser then solder regulator IC KA 7632 and STR.If PS condenser holds charge then check/change EHT output transistor. Thank you.

      HI Francisco,

      You have to get back the IC from him or find the new one with programs in it otherwise it would be hard to repair the tv. You may have to try search from tv repair forum in eserviceinfo.com because I do not keep schematic and IC memory.

      Double image could be caused by bad lcd panel or firmware problem. Is the OSD menu normal?

      If the OSD menu also has double image , it could be the problem of t-con board or LCD panel. If the OSD menu is OK then check the T-con board.

      If the horizontal drive and output transistor is Ok then no need to replace them. Just check all the components in the primary side and direct replace the power ic if the power fet is shorted.

      Hi Boby,

      You need to find the service manual to enter into the factory service mode and see if has the mode to power up in AV mode.

      Hi Amanuel,

      Probably shorted HOT or flyback. I suggest that you isolate the B+ supply line from going to the Flyback and see if the main fuse will blow or not.

    When i isolate there is not short..but when i am checking the secondary output on the transformer i have get the same kinds of voltage on the secondary diodes...the first diode going to directly on the flyback that give 120v...at the same time the another diode also have 120v...and when i cheack the to output diode on the negative side it shows on my multimeter as a short......so what u give me advise at last and how do i know if the flyback is short....tnx a lot justin...God bless u!

      Hi Amanuel,

      You need a ring tester to check the primary winding to see if it is shorted or not. Ohm meter can also be used to check if the flyback primary winding is shorted or not.
