Hi,

By service port they mean a device hookup that a tech can use to diagnose problems with your TV. There is no practical use for you to plug into it. If you want to display your laptop on the TV you need yo hookup the video out from your laptop to the TV's PC/RGB input.

Hope this helps FixYa,

Chris

My Samsung started doing that and it got worst and worst. Searched the web and find answer. It was the high voltage circuit. All TVs now are like computer and it check for 390 to 400 volts and if it is below, the TV will not turn on. Good thing the Samsung has only one capacitor showing the high voltage circuit. Measure the voltage was 381 volts. The capacitor was rated at 100 uf at 450 volts. From some old TV and power supply, got two capacitors rated 150 uf and 220 uf both at 400 volts. Had to connect them in parallel and took out the old capacitor. Now, my TV works fine.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window " to get gathered related posts. .

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices

If the video from your DVD player is good, it suggests that your problem is not the video board! Have you swapped the cable coming in with a "known" good one? Also, have you got your source selection set for DVD player still, and not CATV? That's all I can suggest with the info. available. Hope this helps!

Hi James,
The main board of your TV is not accepting HDMI input. You can use another AV input to watch the TV or you have to change the main board.

Its rare but i have seen a few TV's require the digital main to be replaced for that problem . But if your pickup sensor on that board is bad it should be easy to replace & nothing to program .

If you took the batteries out of your remotes to change them, they possibly lost their programming and need to be reprogrammed. I drop my controller often and have to reprogram it. All of the lights light up but the TV appears dead. Either find your control programming guide or look it up on the internet how to reprogram your remote.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and precious time.

Check its user manuals' specification page. If the set has digital reception capability, the details will be there. If it has no digital tuner, nothing can be done. Gopakumar Gopalan Google
