SOURCE: Emerson 20 inch flat screen tv problem

i had the same problem with a 32 inch and i kept "clicking" the channel changer on the remote to force the tv to go to another channel (that had previously been selected during the initial auto scan) --- still trying to figure out why the tv locks onto the scanning for channel

SOURCE: HDMI connectivity

I have the SA8300HDC STB from Time Warner. I get this error from my DVD recorder, not from my HDMI connection. I've read that the error is due to copy protection. The only solution I've read about has to do with a new Samsung Set-top box from TWC. Funny this copy protection error didn't ever come up with my old VCR connection to the HDTV. TWC apparently told a lot of people that the problem would be solved by a software update from TWC in October 2007 & then in December 2007. Guess TWC isn't sure what the problem is but everyone who has mentioned this Samsung cable box has reported success with their HDMI connection.

SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing

The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;
One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field. Therefore a replacement is required.
Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Five, Seven, or Eight Blinks: The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.

SOURCE: Samsung LCD tv - Turns on and off by itself.

Not sure if this is the same problem, but I just moved and set up my Samsung 40" LCD and it has been going off and on by itself with the worst yesterday every 2-3 minutes. After speaking with a friend of mine who is not in the Tv business but just has good common sense, I determined it was likely a bad power strip. The bottom line is I replaced the crappy power strip (which was fully loaded with all 6 outlets in use) with the higher quality one I had in the other room. The problem is gone. I suspect the power strip was failing or real bad quality........try plugging the tv directly into the wall outlet first. hope this helped.
