Had convergence board replaced. 7months later both top and bottom of screen squeezed in and colors all distorded.Fixed convergenced board again did not fix problem. Now trying to replace power def board. Any help would be nice. TV repair man said worth fixing. Yes if he knew what the problem was.

Hmm very tought to fing your solutions to this problem, since the troubleshooting steps for this issue does not exist for this model on the Samsung website anymore. I can tell you though that not even a Tv repairman can fix it unless he really knows what he's really getting himself into. So it is really up to you now to decide wether if you want to spend a little bit more money on this old tv or just get a new one. Think about it because you know if you really decide to fix it, it will happen again sooner or later because of the age og your Tv. Good luck!

Hi and welcome to FixYa,

Initially and based on your description (squeezed on both ends) of the Samsung HCN529W, it is a convergence problem. This is a known and common issue and should be repairable even on a user level. A complete repair kit that include the replacement (better) STK392-180 (pair), resistors and pico fuses are available from http://servicemanuals.vstore.ca/, pls look for Slinteriors who is also a member of this community. What is good is their repair kit comes with instructional sheet how to perform the repairs.

Good luck and Thank you for using FixYa. Happy Holidays.

From description it looks like a convergence problem again, it would be useful to know if the old convergence board was faulty, if the convergence board keeps blowing it can be a faulty power adapter the cause.

    The only choice is taking the TV to a repair shop, and leave the TV in there to be tested thoroughly, this does not look like a common problem.
    I do not have the schematics to go deep into the problem, but if the convergence ICs, or something else on the C board keeps blowing, it can be a faulty PSU, if convergence board is fine when tested, and convergence setup did not solve the problem, then there are several chips on the main board that must be tested, following the diagrams on service manual. This job take time, it can still be worth repairing, ask a quote to a local repair shop.

1/3 of picture becomes partially scrambled


sounds like you have a frame fold-over fault, does banging the tv have any effect (slightly bang the set on the sides), if it does then its more than likely a dry joint, check all around the frame output chip, hope this is of some help to you
