Here's the link to the user manual; http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=us&CttFileID=32370&CDCttType=UM&ModelType=C&ModelName=HCN553W&VPath=UM/200310/20031002105141187_P55A_00054A_0410.pdf Check page 28 and 29 for convergence instructions. Give it a try to see if it makes any difference. Check page 27 for the "perfect focus" feature and see if that helps. Could you take a photo of the "diagonal lines" on the set and post it - might help? If you open a menu on the screen, does it also have the lines across, or is it clear as normal. Check page 64 for how to run the demo, and try that. Have you recently unplugged the set from the mains power supply, left it for at least 15 minutes (preferably two hours) then turned it back on? if not, try it and see if you get any change. Check page 38 for the usual video settings - play around with them and see if any significant change? Check page 39 and set the "automatic picture setting" to standard, if it isn't already, and something else if it is - see if you get a change. Check page 40 for the colour tone adjustment - probably won't change anything, but worth a play in case. Check the bottom of page 46 about channel fine tuning - reset at least a couple of channels to 00, see if that makes a difference (long shot). Does the screen itself need cleaning? recommended is just a clean dry cloth - basically have a good close look at the screen when it is both on and off, to see if there are any marks that might be causing the problem - in particular has it possibly been cleaned with a solvent or too aggressively cleaned in a diagonal direction? shine a light on it at a few angles to check, and look from a few different angles too. Check by moving or turning them on and off if any other electric or electronic items near your tv may be causing the effect - speakers perhaps. Move speakers to check. A way to check other items is to totally cut off the electric supply to the whole house for a couple of minutes, except one circuit into which you can plug the TV and a picture source. See if you get a perfect picture - if so, start switching circuits back on 1 by one until it changes. Hope this helps - I think a photo would help a lot :)

What you are sseing is a convergence problem within the light engine of the set. This is not repairable in teh field other than replacing the light engine part. Since this unit is less than one year old, it should be covered under warranty. From the looks of it, one of the LCD panels has shifted internally. Call for warranty service and indicate that the light engine has a problem. With luck, the service company will show up with the part in hand. Replacement should not take more than an hour or so.

I've found the lines caused by the digital board before. Unfortunately it is expensive. I'd recommend running it on HD and it will bypass the faulty circuit. The lamp light flashes telling you the lamp is firing up. As the lamp ages, it will take longer and longer until it fails.

Hi.

Just read your list of problems The first fault (Diagonal lines & picture collapse from left & right) Sounded like either A poor connection or dry solder joint either on scan coils or scan coil plug / socket on main pcb.
If this were the case the engineer that called out should have spotted this & sorted it very easily. But you say it is still the same so what did he do ?
Did he give you a reciept with break down of what he did ? If yes please post it here for me to go over.

The sound problem you describe has thrown me a little so could you please post your tv model number on this page so I can see if this is a stock fault.

The static shocks you are getting is relatively normal & not a problem unless you are getting them off of speaker grilles or even tv casing if it is silver in colour.
I am UK based & have access to samsung technical but I will need your tv model number.

Samsung HLM507W will not turn on Alright so here's the deal....I got this TV for free from a guy on craigslist. He said he couldnt get it to turn on. He replaced the lamp, it still didn't work, so he gave up and now I have it. First thing I did was try and turn it on... The TV powered up for about 5 seconds, and then the screen started to flicker all kinds of crazy colors, and it shutdown shortly after with all 3 lights blinking. I figured this probably has to do with the color wheel, so I bought a new one and popped it in. Once installed, the TV started right up, and worked for the entire duration of it being on (approx 7 hours). Now it will not turn on. Here's the startup sequence: -Push power -A couple of audible clicks, and both cooling fans energize. -Lamp does not turn on, and after about 45 seconds of having just the fans running, the TV cycles off and tries to power itself back on. -Rinse and repeat about 3 times total. -After the 3rd attempt, the TV shuts down completely and all 3 lights start blinking in front. -Pushing power does not do anything with the 3 lights blinking. TV must be unplugged and pplugged back in before sequence can be attempted again. Looking for a possible solution/troubleshoot technique. Checked the fuses and they are fine, triple checked all of the connections. Seeing as the lamp doesnt even attempt to energize, Im thinking it could be the ballast, but I'm trying not to dump money into something that might not fix the problem. Thanks for your help!
