HCN4727W Convergence issue

HI,

I have a local shop and I am having some problems with the convergence board on a HCN4727W. Quite a few components are burnt up and I can't tell what value they are. I was hoping you might have a schematic and be able to help me out. I need to know what STK's it needs. Locations: RZ142-RZ145, CZ141and CZ140. My email is KC8LQU@hotmail.com. Thanks in advance.

Repalce STKs with 392-040 resistors should be 3.9 ohms,also you might want to join Repairworld it is for members who have TV shops over 7,000 different shops / lots of good techs there.They will not put up with anyone just looking to repair there own tv .Sorry unable to help with cz140,141.will do some checking you also can order whole convergence board.

"Perfect Focus" problem on Samsung HCN4727W


You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Thats a convergence issue. you will need to replace the two Convergence IC and quite possibly a few of the 6.8 ohm resistors. You can get the phillipd DPTV305-DPTV345 convergence repair kit from www.tvrepairworld.com the kit works for your model also and it includes the ICs and resistors plus the CD with detailed repair instructions.

HCN4727W with Convergence issues


Mike,
The ICZ designations on that board are two Sanyo STK392-040 amps used for convergence. Rz142 through Rz145 are the yoke return circuit are 3.9 ohm 1/2w resistors. CZ140 and 141 are two electrolytic radial 22mf/50v caps in the feed circuit for those amps.
My question would be - and I've NEVER seen this, in my 30 years in electronics, what caused such a domino failure? The amps are basically LV fed by a +/- 24v line input. If the yoke(s) were to short shouldn't cause enough feedback to destroy the convergence board in the manner you've indicated here. That's a P58A chassis used in several models of the Samsung and Akai designs. Only trouble I've heard of with those boards are cooling and most techs have taken to installing cooling fans directly on the board, driven by the +/- 20v line. That drops the temp several degrees and allows the amps to operate at a much cooler temp. We rebuild those boards here on a daily basis and add the mods for greater reliability. But other than that the P58A is considered a bullet proof chassis.
Hope this helps!
