Question about Projection Televisions

1 Answer

I am unable to align the red convergence on my Samsung HCM4215W rear projection HDTV. The factory "perfect picture" has displayed "no sensor data" since the set was repaired in 2004. The set had worked fine for the past 4 years after that repair and just failed suddenly after we returned from a 2 week vacation.

Samsung HCN5529W 55in Rear Projection can't Perfect Focus


hello What you have is a convergence problem. There is 2 modules inside your set that aligns the colors to have the same geometry and superposed . It is a common problem in rear projection tvs ,
You don`t have to worry about your blue tube , i`m sure it is perfectly fine, it just needs to be aligned through the convergence circuit.
Most often the problem is with those convergence modules that are faulty and need to be replaced.
Hope this will help good luck

Color alignment problem


You will need to put the unit into wahts called service mode because it will have to totally realigned since you change the whole module you changed the chip that had you stored memory setting for convergence called an EEPROM. here in the shop I would unsolder the old EEPROM and put it on the new BOARD. Also on most models you don't have adjustments for the green you have to move red and blue to match green. Imay want you to describe again to me what you can adjust now with the new board in the unit can you move all colors left right and up/down

It probably is see if you can align the convergence manually or auto if available, you can order just the convergence ic's or the convergence amp board, whichever you prefer. check pricing and availability. also check Blue crt for faded picture, usually dirty crt fluid, makes picture dark and discoloured. If it is you may need to replace the blue crt also. this gets a little expensive, again check pricing hope this gets you started RFT
