Hi, I have a Samsung LN40A550 LCD TV which I have had for just over a year. ... I was watching TV yesterday and all of a sudden the picture went all. ... started makinga very high pitched buzzing sound with no picuture coming on. We did have a bunch of green vertical lines, but now just a black screen.

John, I hope you know that changes of this nature should be IMMEDIATELY referred to YOUR Physician. If you are taking DuoDart and this change has taken place, there is something effecting you adversely. CONSULT YOUR PHYSICIAN...

Sounds like an inverter problem. On some of these sets, the inverter and the power supply are on the same board. These boards tend to be quite pricey, $100 + range. I've worked on your particular model with the same problem, and it was a bad inverter/power supply board. I would recommend you get a diagnosis to be sure.

Most of these sets have two tuners--one for main and one for PIP.

If main picture works fine but PIP is bad or Green? either the PIP tuner or the PIP board is bad---these were known to have the PIP have problems but it was more rare than their sets made before it.

He is probably not an expert (just kidding, of course he's not..) First, try connecting the Cablevision Box to another TV (if you don't have another HD TV, use the yellow/white/red Composite connection.) If there is still no picture, the box is no good. If there is, then try a different output from the Box or other inputs on the TV. Are you using HDMI (HD connection) out of your Box? Is the TV 720p or 1080p? Set the Box up (from the menu) according to the specs of your TV. Hope I helped.

id take it and have it repaired. people on here can tell you what they think it is but no one knows for sure what is causing the problem. a repair shop can guarantee the repair.

If your pic is in the locked mode (Green Key Icon). Bring up picture. Press menu. Press (Playback Menu) and hit OK. Press OK again and it should bring up the pic with option of off or on. Hit off to unlock and you should be able to delete the pic.
