Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....



  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Colours are distorted. The screen convexes towads towards the sides, and top and bottom. The 3 main colour filters -- red, green, and blue -- do not line up with the picture image.


you have a convergence problem and nedd to replace the convergence ic's i think the part # for the generic replacement is stk392-110-there are 2 of them. you also need to replace( check 1st with an ohmeter) the 4 fuses associated with the power supply going to the convergence ic's-they are solder in fuses and you have to know the value to put in the correct ones. unless you are a technician, i would suggest call for service ont this, but feel free to give the tech this info.

resolder the vertical IC that is whats making the CRTs go blank. Its a safety issue where the CRTs blank when there is no vertical deflection. Just resolder the output IC that should cure your problem

Samsung hc-p4741w flashing red light


That sound is made by the power supply who's gooing in protection mode due to some overcurent in secondary. Could be many reasons: conv. amp. IC's, video amp.IC's etc. In my opinion more then 70% chances to be the STK for convergence. Need to be troubleshooted by a tech.

Pincussion/Geometry/Convergance Problem


If you can not correct the convergence with custumer settings is because something went wrong inside the tv and it has to be diagnosed and corrected by a service technician,you are correct there are setting you can access with the remote but are usually adjusted after you have replace a major component.I would suggest you call for service,I do not believe is a problem you created or you could have prevented.
