The capacitors on the power supply need to be replaced. When you take apart the TV, and then remove the power supply (it's the section that the power cord goes to) and open it up. Look for the little can capacitors and see if any of them are bulging on top. That is the sign that they've blown. Replace the big ones (about 5) for about $5 in parts. Reassemble and test by turning it on. Search for YouTube video on how to replace capacitors.

Possibly capacitors on power supply PCB have failed. If you are competent in electronics a visual check could reveal problem.

It depends on the laptop connections. First make sure that your computer is sending data to the port (particularly VGA); you may have to access the BIOS to change the setting (often F1 or F2 on restart). If you have a VGA port on the laptop, get a video cable (VGA-VGA) and connect the two together (this is usually a blue port and you need M/M ends). Then enable in the graphics properties (right click on the display where there are no icons or running program). You want the section that lets you choose sending to the external monitor, the laptop monitor or showing the same contents on both. The version of your OS may alter which command you need (you can also access this in the Control Panel (Display). You may need to restart the computer with the TV on to get the computer to recognize the TV. Set the TV to have the source the PC input. Also connect the speaker cable from the laptop to the TV if you want to use the TV's speakers (there is an audio port next to the VGA port that I believe is a 3.5 mm jack (would need a stereo 3.5 mm m/m cable between the two). Make sure you select the optimum resolution of 1360 x 768.

If you have an HDMI port on the laptop (newer laptops), get an HDMI cable (m/m) and connect the two. Set the TV to DVI or HDMI source (depending on if you need the audio cables separate) and reboot the computer. Then enable the display, as above. I believe you still need the audio cable as well (should use a 3.5 mm stereo to RCA R/L (red/white) cable) look for the DVI audio next to the HDMI/DVI port.

I hope this helps.

(my understanding is that computer HDMI ports do not send the audio but you should check your laptop manual.)
