I have an Acer AL261W. I have to turn it off and on with the switch on the back several times in order for the tv to respond to the remote or the buttons on the tv itself. It started of with having to do this occasionally, but now I have to do it all the time.

Hello,

Electrolyte capacitors on the powerboard are going bad and need to be replaced and the tv will work good as new.

Here is a picture that helps you spot the bad capacitors, they can bulge, leak or blow. in your case since it still starts up they are most likyl bulged like on this picture or possibly leaking under.

these need to be replaced with same UF rating and Voltage capacitors, they cost around 0.5$ or similar depending on how many you have to replace it may end up costing around 5$

note that you need a soldering iron and the old capacitors need to be unsoldered and then new ones put in place, you need to make sure they are put in the same way, make sure you match the negative to the negative or minus to minus.

the minus side will be marked with black in most cases.

note that the capacitors may hold charge even when unplugged, use a multimeter to check that they don't have any charge before replacing to avoid small electric shocks. The bigger capacitor if not discharged may hold up to 400Volts and could be deadly.
