Good day!Follow this D.I.Y procedures to find the exact problem of your TV.
\012
    \012
  1. Remove the back cover of your TV.
  2. \012
  3. After that,find the power supply board.
  4. \012
  5. If you already found the power supply,plug-in your TV \012and power it ON.Check the input voltage of it,using multimeter (AC \012range).If the power supply have no input voltage the problem could be \012the power cord.Replace it.
  6. \012
  7. If the power supply have the input voltage,try to test \012the output voltage if have 5vdc for the system and logic supply,12vdc \012for the sounds and 24vdc for the back-light inverter.Use your multimeter\012 tester (DC range) to test that.
  8. \012
  9. If the power supply have a voltage outputs such as \0125vdc,12vdc and 24vdc and the problem is still there.The problem could be\012 the main board.Replace it with the same type and model # because the \012main board is no very difficult to fix and its very sensitive.
  10. \012
  11. If the power supply have no output voltage or the voltage is too low,just ignore the step # 5 because the problem is not on the main board,its on the power supply board.
Check the following to fix the power supply board:
\012
    \012
  • Fuse: Check the fuse if it is busted or blown.
  • \012
  • Power transistor (regulator): Check the regulator if it is shorted or leak.
  • \012
  • Resistor: Check the resistors specially the one that have a low resistance that near the power regulator.
  • \012
  • Capacitor: Also check the capacitors if it is leak or bulging top.
NOTE: If you found any defective parts or components that mention above replace it with the same value,type and ratings.

I hope this solution will be helpful.Thank you and good luck.

Doesn't power up. Relay clicks several times, several seconds apart. After third click, power LED blinks three times. The OPC LED blinks once when the power LED blinks the first time. LED blinking pattern repeats every couple of seconds. Opened up TV to check capacitors. All look good. Purchased service manual, but there weren't troubleshooting steps for the power board. Any suggestions as to which board should be replaced first?

Problem with TH-C50FD18:Gives off 2 blinks I replaced the D-board and the A-board to no avail. The power trips the moment the 15Volts ON occurs to send 15volt power to SS, D-board, A-board and SC-board. I found no short on this 15Volts line that is switched by the MC701 Power MICOM Processor. It looks like a 15Volt error is detected, nonetheless.That's why it always reverts to standby mode. Could this be a 15volts power regulation problem?

Display Flickering The display on my Samsung LN46C650 is flickering. Many have reported this issue with the tv with most blaming it on cheap capacitors, some blaming it on a missed wire snip during assembly, and yet others blaming it on power cord. I started with the easy step and replaced the power cord with a known good power cord, no such luck. I contacted Samsung and they told me I would have to take transport the TV 2 hours to the nearest service center for an estimate to see if they would

Okay, so my Panasonic PT-43LC14 went black in mid show last night. The bulb is approximately 18 months old. The LED indicators upon Power On are; Power LED blinks green for approximately 70 seconds; Then the Power LED switches to Red Blink, and the LAMP indicator blinks once every 5 seconds. Service manual indicates this means lamp or ballast issue. I've inspected the lamp, and it doesn't appear to be burned out. I've disassembled the TV and check the ballast for visual issues and see none.


Check the bulb again and look at the root of where the main stem comes out inside and be sure you don't see any bubble like appearence around the stem at the bottom there. If you do see this then the bulb is bad. Otherwise try this: Hold volume do ... Panasonic PT-43LC14 43" Rear Projection HDTV

When I turn the TV on, the green power light comes on, then it turns red and finally begins to flash. There is no picture at all. I can get into the service codes via holding Volume down and input while clicking main power and get the "K" indication and can get menus with VOl up and Channel down. This should confirm backlight and power supply. Could there be a synch error?

I have a Samsung LN40A550P3FXZA that is giving me problems. When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came

We own a Sony FWD-50PX2 television. A few weeks ago it would not turn on. The power is going to the television. When you try to turn the tv on you can hear it pop and the red light showing it is off will flip to green and then turn back to red. We would like to just repair the TV as it is a very nice television set. We thought possible power supply, but it is trying to turn on. Any help you can give to help correct the problem would be great.
