After having problems myself and discovering many other people had same problem with the SAMSUNG SP43W6HL (quite a few on this site) and using XBOX 360 AND PS3. I too had the Blue Screen when using VGA HD Cable and couldnt get it to work in HD. After a bit of research I discovered these TV's aren't HDready despite displaying the logo on the front. You cant use and XBOX360, HD DVD PLAYER , PS3 etc with them in HD mode. They dont have an HDMI socket which they must have to be HD compliant., and all those people struggling to get there games consoles to work in HD are wasting their time cos they wont. I sent a complaint letter to Currys Customer Care Department explaining all these facts and they had breached numerous regulations by selling the TV, and within 4 weeks they rang and apologised. They were very apolgetic and willing to solve the problem. They blamed Samsung but regardless they were willing to give me a new tv. The same day I went to my local Currys to see what was available for immedaite delivery after the woman at Currys Head office (Liz) told me to see what I wanted ,and was able to spend ?900 on a new LCD HD TV, they even let me have the stand as I obviously didnt have one with the Samsung having it own built in. Dont worry about time limit on your purchase ours was over 3 years old yet they know they were at fault or Samsung were. I sent a few photographs with my letter showing the HD Ready logo, 1080i logo etc, gave them the place of purchase and approx date (Month and year). They have customer records so they can pass on your details to TV licensing. So if you havent got the receipt dont worry. Also if you purchsed an extended gurantee I'd ask for your money back or a free one on the replacement TV.
So hats of to Currys (Makes a change..LOL) for solving the problem and those with the televison even if you aint got an XBOX 360 or PS3 tell them to have. I told them my wife had bought me a PS3 for xmas and I wanted to play in HD. I have got the XBOX360 so know it defo doersnt work and had tried my mates PS3. They did offer money as way of compensation and for me to keep the Samsung till I told them I wanted a TV that was HD and not the usless box of nuts and bolts I currently had.
If any one wants an edited version of the letter (I'll leave in all the legal jargon) and they can insert their own details (address and purchase details etc) and personalise it a bit so we're not all sending the same letter then email me at ANDYSJ3@GMAIL.COM
and I'll happily send them it. It worked for me and will hoepfully work for you.
For the record: This product clearly does not meet the standards under EICTA Regulations and its HD logo in which it was sold, as HDTV must accept 50hz/60hz@720p/1080i to meet these regulations. Also must have at least 1 HDMI slot to be HD ready
