Question about Samsung HCM422W 42" Rear Projection Television

Samsung SP42W5HFX colour misalignment

A couple of days ago my nephew (little git!) hammered on the screen of my tv and now the colours are out of alignment. It seems to be mainly the red which goes off to the right with a bowed effect. I've read a few posts on here which refer to the convergence board, which I have seen advertised for around £70, is this easy to replace? The TV is a few years old now so I don't want to spend too much putting it right... I paid £1600 for it 5-6 years ago, but you can buy new now for £500!!! I had an engineer look at it, but he said as an independent Samsung won't sell him parts or provide a manual! Any info/suggestions would be very much appreciated. Thanks.

    Hi Chris,

    Thanks for your input re my TV, I tried using the covergence menu ,but I couldn't get any of the crosses to line up at all!!! Presuming I was doing it right, (by no means a foregone conclusion!) does that mean the convergence board needs replacing? I don't want to spend £70 for nothing but it would be nice to get it going again reasonably cheaply, cos I'm using a 14inch portable at the moment!!!!

    Many thanks for your help

    I have had exatly same problem. Bought my TV July 02. The colours will not converge and I have no control over then in the set up menu. The red is most affected, when you look at a blue screen there is a red line curving in the top left hand corner disapearring about 2/3 to the right.

    Did you get this fixed, how much was it ??

Hi. Did the ngineer say that it was problem with convergence pcb ? To be honest the lil git hitting the screen is more likely to damage the screen than convergence. Try going in to the menu then convergence & adjust red & blue to try & get the crosses white with no coloured halo around. Post on here with results your model of tv is pretty straight forward I work for an indepedent tv repair shop the manuals are easy to get hold of thats if he even needs one. Chris..

    The board wont need replacing just the 2 ICS & possibly resistors.
    £70.00 is not a bad price at all to have the work done the 2 chips can vary in price from £15,00 to £30.00 each depending on there exact number.
    If I were you go for it & get it repaired there will be some setting up that needs to be done by the engineer after the parts have been fitted.

    Regards Chris
