My old Samsung 32" flatscreen has started being difficult when I try to power it up from cold. Using the DirecTV remote to control it (which I have done for many years), pressing the system power ON button powers up the satellite box immediately and consistently, but the TV takes numerous attempts (like 6-10) to finally get started. Red power LED on the TV flickers when the button is pushed, so I know the signal is being received at the TV. Power button on the TV itself does absolutely nothing. I'm assuming this is just an age-related failure and the remedy is to replace the unit, but I figured I'd check here to see if there was some magic solution I was not aware of. Thanks.
Bad capacitors in the power supply, backlight inverter board and/or other locations are the likely culprit. There may even be a kit for your particular model. Can you solder?
I was just thinking is it a samsung when I read the title. Well known issue with the Power Supply Boards in samsung TVs. I had 2 go out in mine. They were really bad about 5-7 years ago. I ended up ditching the TV as the replacement boards sucked just as bad. The only good thing was they were easy to replace.
A brand new 1080p 32" TV is about $150 at Target or Best Buy.
That (to me) is enough to just warrant buying a new one. Sell the old one to someone who likes to fix them for $25.
New electronics are so disposable and (aside from bmw88rider's Samsung experience) require an electrical engineering degree to diagnose and repair.
I was guessing it was a capacitor problem. Given the age of the unit, I don't think it's worth trying to repair, especially given how cheap new ones are. Thanks for the confirmation.
Use a vacuum cleaner to suck all of the dust out of the cooling vents.
a) you may be surprised how much is in there
b) the blockage can cause the tv to essentially go into limp mode
Might not entirely solve your problem but it's too easy of a solution to not give it a try.

Well, I just ordered a replacement this afternoon, so this will be purely for scientific curiosity, but I'll give it a shot. Wouldn't dust act as an insulator and cause issues when the set is hot, rather than when it's cold? Or am I missing some other aspect of the (potential) issue?
