How do I fix a Samsung LN37A550P3FXZA that has flashing red light and black screen cycling on and off?


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Color is distorted/washed out is it worthwhile fixing if DMD module is bad?Samsung ln37a550p3fxza


The DMD boards were used in earlier DLP sets but I do not think this set --model is a LCD set uses that but has a main board instead---you may want to do some research on possible boards for this model which should be LN37A550P3FXZA and not IN.
