My samsung hdtv (model # hcl552w) displays a blurry screen

SOURCE: Diagonal lines on my screen(samsung 55" projection HDTV hcn553w)

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 :)

SOURCE: my samsung projection tv #pcl5415r don't want to perform perfect focus adjustments

perfect focus functions are based on service mode setup...or factory settings. if the alignment of these setting are loss then the unit wont perfect focus. does the unit have a complete loss of convergence. a complete loss of convergence indicate possible failure of convergence amps.

hello,

Thats need an over all cleaning in the circuit and resoldered all loss components and this will fixed the problems.

Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

SOURCE: I have a Samsung HL-N4647W 42 inch HDTV DLP TV and

The tv have a problems known as a convergence problems,it dead.The tv have colors lines R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
