SAMSUNG HCM4216W has a verical line

I have a samsung hcm4216w I have taken in twice to get the convergence fixed. The last time the power wouldn't turn on so I took it in to get fixed now there is a vertical line that runs about 1/2 of the screen. The repair guy said it was the red picture tube and wants another $400 to fix. any suggestions

The vertical line has nothing to do with the picture tube,Some component in the horizontal circuit is causing that problem,most likely an electrolytic capacitor

Samsung hcm4216W turned off by itself loops.


Instead of typing model number of your TV (that located on right hand side and on the back of TV) you published here part number of your TV's remote control. LOL.
Anyway... If it is LCD/plasma panel that you talking about - than power supply have bad electrolytic capacitors that have to be replaced. You can recognize 'em by bulged/swollen tops (instead of flat tops of good capacitors).
This repair required soldering skills.

Sounds like your convergence circuits shorted and took out the resistors. This is fairly common.

This is a common problem. Its called a convergence failure.

Problem #1) Convergence

Symptoms:


  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms

  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

Red and Blue convergence issues cause triple-image


This sounds like your convergence chip is bad. If you are good at soldering you can order the replacement kit from www.tvrepairkits.com and do it yourself.

Red blinking light


It's most likely convergence -- the small board up and to the right inside the back of the TV, which has two large amp Ic's attached to it..
Unplug the +/- 20v line on the fron left corner of that board (red in color) and then try and power on the set... If the set comes on the board needs to be repaired and it's an easy unplug and two screws that mount it inside.

The most common problem for those symptoms are convergence amps. That unit takes two stk392-040 Sanyo Ics and will most likely require that several low ohm resistors (3.9 ohm-2w) be tested and possibly replaced.. There is one last thing also, a pico fuse at Fd102 (3.5a) that sometimes opens and would need to be replaced..
The convergence board in these is easily removed, so an in-house service call could be done...
Hope this helps

Blue and Yellow doubles


Well, fortunately the television that you purchased has an auto-convergence feature. What is happenning is that your color lamps are misaligned, did it get moved at all recently? Anyway, in your menu you should see a "Convergence" menu, and inside that menu, a section called "Perfect Focus". Run Perfect Focus in this sequence: Green --> Red --> Blue After that your picture should look great, if not try tinkering with the manual adjustments on the "Convergence" menu.
