Probably the power supply. Look for bulging or leaking capacitors

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 is likely a heat issue, and the CPU of the tuner is instructing the power board to switch it off for reasons related to over heating. Check that a fan ventilation improves the problem. The solution is not easy but maybe adding a fan to the tuner CPU can fix this issue.

If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability? Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device you have. Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its user manual. Never accept a remote control, that hasn't both of this.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors - Flickering screen - Screen image disappears after several seconds - Dim screen - Slow start - Power LED on, but no picture - Unusual colors and/or lines The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad. If they appear bulged on top, then they need to be replaced. New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years. Take it to a repair shop.

Good morning Cheri try restarting the tv, just disconnect all electricity for 30-60 sec. connect again. If that does not work, Try set- up on the menu, if you get the apparatus to obey you and leave the input mode. If that does not work I always restart the router and "exchange"box, enjoy your day kolbrub

You can't turn CC option OFF, without its remote control.

I also have some problem with the hdmi cable connecting.

If the problem is same with different input devices and you have ensured the are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

Please search for free service manuals online.

Change input device to some other like a DVD player and see. Check for loose contacts in power outlet, RC cable, jack and socket.

no you wont hear a sound if your power supply is bad.try to go where you bought you tv because it may factory defect.hope it helps you

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Main board is most likely but that is an educated guess--problem with all these is you can only check so many things and then have to guess and try a board.
