Question about Samsung PCH521R 52" Rear Projection Television

1 Answer

Convergence is completely messed up and Audio drops

I have a Samsung Tantus PCH521R since 1999 and now every time I turn on the TV, the top half of the screen is completely messed up. After about an hour, it clears up - but the top potion still is not 100%. Both speakers work, but only one plays most of the time. Sporadically, the audio shuts off and I have to raise the volume really high for it to come back.

The convergence problem is more of an issue and I would be grateful if someone knew exactly what needs to be done. Can it be a convergence board replacement or something of that sort? Samsung is no help as they only want to send out a technician which will be an arm and a leg. If I know what to replace, I'm technical enough to replace it myself.

Can someone help me?

    Hello Dorothy - yes I have been able to configure the convergence myself (mute 1-8-3). I've done it numerous of times and now I think the TV convergence is just shot. I am unable to straighten out the top (2) lines - it has a constant jitter and is slanted. Plus the BLUE lines are no longer available to setup in the convergence mode. I'm only able to fine-tune the RED and GREEN. The entire top half of the TV has this jitter as well when I first turn the set on, so I know it has to be something much bigger.

    Greetings slimice,



    Have you been able to perform convergence yourself via the setup menu on this unit? Or is the problem of much larger scope?



    Awaiting your response,

you need to general service the whole unit. this will include re-soldering and changing some defective components from the board, which has been damaged through using from past years. my advice is to have a quotation from service tech and then think about repairing it..if it is better to buy a new one..
