    Please help: I have a Samsung HLS5679W model 52" TV. Recently, when I turn the power on in the morning, it starts blinking all the three lights, then shuts off completely after about 5 minutes. When I turn off and on the power, it seems to work, similar to rebooting your PC. But, now it completely shut off. I can't turn it on. Can anyone help. I saw above from Solution 2, it could be a power supply issue, which is helpful. That gives me a good clue. Can anyone give me a suggestion, if encountered similar problem with this TV. I will v. much appreciate.

HLS5679W has power supply issues. Two capacitors need to be replaced as Samsung put in units of the wrong voltage...
CM860 and CS860 need to be at least 2000mfd/25vdc radial (both leads come from one end) electrolytic capacitors. It is recommended to have a service tech do this you'll need to pull the power supply out of the set. Parts are cheap (Radio Shack for about $2.99 or so each) but you must be able to solder to replace...
Good luck!

Tv won't turn on. All three lights flash in sequence power heat then bulb. The bulb appears to be in tact.

I will need the model number of the set in order to assist with the issue as the three lights blinking is an error code which would be different based on which model number TV you have.

did you try new batteries in the remote? if the tv has buttons on the side and one of them being power di you try to push that? did you push tv power or cable power holding the buttons longer? those things might work.

A possible bad lamp if not replaced recently or removed and at least examined. What is model number and what have you tried so far?

I have a Hitachi 53uwx10ba power light flashes and tv won't turn on

It is rare in this set but it indicates a short somewhere that is pulling voltage inside the set down---not a do it yourself repair unless you are a Technician with some basic equipment and a schematic diagram.

Have someone look at it from a repair shop or ?

WD-65734 Mitsubishi TV won't turn on. System reset

Are there any lights lit on the front of the TV? Have you checked for a bad lamp? When you reset the TV the timer/power light should flash on and off rapidly for 60-70 sseconds. Does that happen?
