When attempting to power-on the 8-year-old TV, via either the set button, or the remote, it just rapidly turns itself on/off/on/off.. back and forth repeatedly, and never does actually show a proper picture. It will continue this until the power button is pressed again. I understand this is probably an issue with the power supply, but it this something that's worth it to fix? TVs are getting less & less expensive, and it's probably about time to buy a new flatscreen anyway.

Try couple of things .hold the volume button on the tv and at same time press the menu button rapidly 3 times.if this does not get into the correct screen try holding the volume button on tv and press the zero(0) button 3 times rapidly and another is to hold volume button on tv and press zer(0) button on remonte rapidly 3 times each o fthese methods these should get you into various set up screens but be careful and take notes if you change settings .you may have to unplug or turn power off at mains and power up again to see changes
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
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...
I have been told by the Acer Support to try two things.
1) Press the left most and right most buttons just left of the Power button continuously for 15 seconds, this is equilvalent to "rebooting" the TV.
2) Unplug all connections to the TV and leave only the power plug attached to the TV, press the Power button continously for upto 30 seconds. This will discharge any electric in the TV.
3) (Actually my discovery, not Acer Support) - Turn the TV on and off a zillion times at the back of the TV in combination with the ON/OFF button from the remote and it will ultimately turn itself back on again.
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.
