Won't turn on

a good tv repair shop is needed by you

8 Months call Manufacturer and let them know,or just take back to store. You should have a 1 year Warranty.

A TV that is turning itself on and off is not necessarily broken. An easy fixed problem is usually the culprit. There maybe a stuck power button on the TV's remote, or the TV's remote's batteries are running low. An internal timer might accidentally be set to turn on the TV then.

Main control board, budget tvs are made with very cheap parts. 2 years is about how long they last

Sometimes it takes a while for the TV to go through this set up such as a half hour to an hour. Just be patient an make sure the antenna is set to air.

Please take these actions before we try yet another universal programmable remote 1. Clean the IR screen on your tv set. It will often appear clear in view with a reflective window which often has a black, blue, or red tint to it 2. Clean the same window on the programmable remote 3. From tons of experience, I've noticed that Sony tends to provide the most compatible remote for replacements 4. Please confirm with me which codes your attempting to use when programming, and type /model number of the universal remote 5. Keep in mind that the remote that does not work as a replacment may very well be exchanged 6. Only use approved batteries for your remote and keep in mind that rechargeable batteries account for 50 percent of electronic errors 7. If your old remote simply stopped working for no reason at all, then we may have a communication problem with the tv combo set itself. 8. Ensure that the tv set is ready and able to receive a signal by setting it to the factory defaults within the settings menu 9. If we know why your older remote simply stopped transmitting the signal, we will acheive a must faster solution 10. Please attempt a fresh set of batteries in the older remote to determine the root cause behind the transmission problem 10. Check your power cord for crimping, dents, or pinched underneath unit. Each of these activities will cause power to stop transmitting to your unit 11. the digital display is not popular for having problems. 12. Ensure that you press the power on button on the digital display firmly at an attempt to power the unit on. 13. If you still have not recieved power, we will continue to troubleshoot the internal portions

Try resetting the TV to factory settings thusly:

Turn on the TV. While holding down the RESET button on the remote
control, press the POWER button on the TV. (The TV will turn itself off, then
back on again.) Release the RESET button.

Does the TV turn off on it's own, or is the remote being pointed at the TV when it goes off - without you pressing the power button on the remote? If the TV goes off with the remote pointed at it (without you pressing the power button), it could be old batteries, or you need a new remote. Have you tried replacing the batteries in the remote? If it's not the batteries, have you got a universal remote lying around somewhere that you can program to operate the TV and try to operate the TV with it? If you determine that it's not the remote, it is probably something to do with the infrared remote sensor, or something faulty in the sensor's circuit board that controls the power switch. How old is the TV? If still under warranty, I would call the manufacturer and explain your problem. They will be able to assist you with any further questions you may have. The number for the manufacturer's Customer Service is located inside of the owner's manual. If you no loner have the manual, you can easily get the contact info via the manufacturer's website. Good luck, and I hope this helps...

How old is this set?
I guessing it is maybe 8 years? In that case I would plan on overhauling the high-voltage circuit because it is going to need it soon whether it is the problem now or not (and it very likely is). Should cost under $200 at a shop. I generally don't waste time on older dead TV's but this is a good model and worth the effort. The risk is that sometimes when the high-voltage fails, it blows up other circuits in the TV and can be a real nightmare.

If you can not turn on TV set with the power button on the TV its not a standby problem as this would by pass the standby. Theres most likly, on a set of this age, top have a poiwer regulator problem and is going to need a trained tech to assist you in this repair.
