DVI cables are usually HDMI compatible. The downside is that DVI usually doesn't carry any audio. Your computer may need a specific audio card to transmit audio/video data from your DVI output to the HDMI input on the TV. You can find one at your local computer store and ask if it is compatible with your computer
I hope this helps...good luck

Look at the power supply for bad caps with leaking/bulging top, and check the CAPS' ESR with meter since cap can look OK but can have high ESR (Equivalent Series Resistance).

There are one or two typical causes of the problems. The 24vdc power supply is bad due to bad DC filter caps, or the backlight inverterter board has short circuits. Those are the two areas to start checking first.

Try using the power cord from your PC. NEMA5-15P to IEC C13.

Check to see if the 24vdc feeding the inverter board disappear whent he sceen goes black, if it is OK, then check the Backlight ON signal on the inverter board, if you do have signal and the 24vd, then you have bad Inverter board, worst case will be bad lamps.

That may be just the co-incident, try unplug the TV from the outlet for 1/2 hour and try again. If it still does not turn on using the power switch on the TV to turn it on, then you will need to open it up and check the power supply.

That can be from the switching power supply or the back light inverter board due to bad DC filter caps in the power supply, that will be the first place to look.

The sound proceesor may have gone out or the power amplifiers that drive the speakers may have gone bad.
Try this first to narrow down the problem, try hooking up powered PC speakers to the Audio line out RCA jacks to see if you do get sound there, if it is OK then you have problem in the power amplifiers section, if you do not get sound, then the sound processor has gone out, both the sound processor and the power amp are on the main logic board, You do do get sound from RCA jacks you may want to keep using it that way since the main board and the labor for repairing LCD TV is not cheap.

Enter code 8202. Master password. This cannot be reset so make sure your children do not find it or they will be able t disable any code you enter.

The standby 5vdc power section is working but the rest of the power sections (5vdc, 12~16vdc, and 24vdc) may not be working.
That will be the first place to look, look for caps with leaking/bulging tops.

I got a tip for this and in this tip are codes you can TRY, now the sky universal remotes are senstive to tv codes so you need to try the manufacture codes if that does not work then you need to ditch the sky remote and get a remote that works with the sky box and the tv as a solution. IN my tip there are remote solutions as well, please do not shoot the messenger I am not sky or the manufacture I am just helping for free,
