When I turn on my tv,the cable will work for about two minutes. I can hear a click like a switch turning off,then the screen will go black and say No Signal. After that the screen will go fuzzy for a bit and then turn back to black and No Signal. I checked the Cable wire from the board to where you hook the cable in the back, and all connections are clean and tight.
Check settings on your source...make sure you are not plugging into a DVI/HDMI port on your TV unless you are in fact converting from DVI to HDMI (there a connector to buy) if thats not it replace the cable with a different one. There are several varities of HDMI cable and the signal is faster as you increase in price normally. I have Monster cables that work Perfectly....I would also check TV settings on the port you are plugging into and try a different one to see if the result is the same. If the result is the same you may have a bad source. Always rule out the cable too.

Go back and check the cable connection. it might be that the video cable is loose. also, confirm that you switched it off properly last time. try turning it off and waiting a few minutes and turn it back on.
If this does not work your av cables may be broken
The PS3 can be hooked up to the tv using either a HDMI cable or the old RCA (Yellow, Red, White) cables. If you are having problems viewing a picture or hearing sound, here is some trouble shooting you might want to try.
Connect the PS3 using both the HDMI and RCA cables. select the HDMI input on your tv. turn on the PS3. If you cant see a picture, press and hold the power button until you hear 2 beeps (this will take about 15 seconds). This resets the PS3 to the old RCA cables. Select the RCA input on your tv. Hopefully you can see the image and hear the PS3 now. Go to the settings on the PS3 and change the display settings to output video through the HDMI. Remember, your tv can only go as high as 1080i resolution, so you wont see anything if you select the 1080p resolution.
If this didn't work, you might have a bad signal though the HDMI cable. Unplug the tv and PS3 for atleast 30 minutes, and then connect the PS3 to the tv before you turn either one on.
If this doesn't help, then you might have a HDMI cable that isn't recognized by either your PS3 or your tv. Try replacing your HDMI cable.
In time as the Sony Trinitron ages it begins to have power issues. While this can be true of most tube televisions it's the rate and severity at which this happens to Trinitrons that makes it particularly of note. Many Trinitron owners have complained of the Trinitron set turning itself off randomly and frequently. Some sets have failed to stay on for longer than a few minutes at a time. Eventually some sets will not turn on at all. These problems grow more severe with age.
Check the power cable running from the Sony Trinitron 32. Make sure the cable is completely inserted into the power connection on the rear of the TV as well as the local power outlet.
Disconnect the power cable from the electrical outlet, then plug it into a different connection. It is possible to electrical outlet has died, forcing you to obtain a power current from a different source.
Check the cable connection running from the cable/satellite receiver or VCR. If the TV is on but no picture is on the screen, the problem is most likely due to a connection issue.
Power off the cable/satellite receiver, then press the "Video" button on the remote control to switch the Trinitron 32 to the video input signal. Turn on the cable/satellite receiver and the programming now loads onto the television screen.
First the main bd controls the "Turn on" sequences". When you press the Power on button the Main bd sends a "Turn on" signal to the Power supply. The clicking you hear is the Power on relay ativating. If the tv does not turn on and the relay keeps clicking then you might have a bad Main bd or there is s shorted board somewhere else in the set. The Power supply can also be bad. Have a trained Samsung tech troubleshoot the set.
Back again. It appears that the key is the order in which you connect things and switch the TV on or off. It took some experimenting to get to what's reliable. I'll spare you the details and confine myself to what works. 1. Start with the monitor cable disconnected at the laptop. 2. Turn on the TV with the source set to your regular satellite (or cable) signal. 3. With the laptop on, plug the monitor cable into it. 4. Switch the source (at the TV) to receive the VGA signal (from the laptop). Voila! To turn off, reverse the procedure.
This denotes a problem with the switching power supply or the high voltage power supply. what is happening is the safety relay is being actuated by the shutdown circuit. Any number of things can cause this proble but more then likely the problem is in the high voltage power supply section and or its associative circuitry. The switching power supply and the high voltages power supply have very dangerous voltages and I would not suggest that you work on the TV set unless you do have a background in electronics. If you do not I would suggest that you take the TV set to an electronics shop for repairs. If you do have a background in electronics, you will need the following items:
1) A schematic diagram (to know where voltage and signal test points are located and to have a reference of the levels.
2) A multimeter (to measure the DC voltage levels on the TV Set)
3) An oscilloscope (to measuer the AC voltage and signal levels in the TV set and compair them to the values in the schematic)
4) A signal generator (to generate a reference signal for troubleshooting)
Many TVs, including some Panasonic models, have an Auto-OFF feature that will automatically turn the set off after a few minutes, if the TV thinks it is not receiving a video signal.
By reinserting the coaxial cable, you are probably restarting the Auto-OFF timer inside the TV.
There are several possible things that could cause the Auto-OFF to falsely activate. Try and change the coax cable going from the VCR to the TV, if you have a spare.
If not, plug the cable from the cable box directly into the back of the TV. Make sure the TV is on the correct channel, usually Ch 3 or Ch 4. (Do not use the original cable that was running from the VCR to the TV, just in case it is intermittent.)
