I need the outer screen for my Samsung HC-P4752W. Mine has a red line that seems burnt into it. Where can I get one?


It sounds like the RED CRT is cracked which will cause a red line. You can verify by looking into the lens of the Red CRT with a flasnlight if you see a line the CRT needs replacement. If no line then chances are the Convergence IC may have a problem.

Short red line in center bottom of screen on a samsung hc-p4752w. I just replaced the stk392-010 with stk392-040 due to failure and the red line was present before replacing the stk's. Convergence is now...


if the ic have been replaced, it may be necessary to refocus the rprojection tubes, this is done by moving the rings near the bottom of the tube, determine which tube and by focusing the lens .. be careful when doing so high voltage can kill you!!

I have a Samsung HC-P4752W and see yellow and bllue halos.


Have you tried to use the convergence function on the TV? If that has not fixed this issue then you have bad convergence IC chips. These chips are microprocessors that align the blue and red tubes with the green (which is stationary). This converges the three tubes to create the image that you see. Failure of these chips (usually from heat over time) is a common problem with projection  TVs. The chips are not very expensive; from $35-60 for the pair. Replacing them involves some tedious desoldering of the old ones and soldering in the new ones. If you have some experience with electronics and soldering it is not hard. Shops will charge $300 and up for this repair. If you want to do it your self post a comment bnack here and I can assist you further.

I have a samsung hc-p4752w and I'd like to find out where I can get an inexpensive blue picture tube.


The blue tube will cost $150-$200 from a Samsung parts distributor. Keep watching Ebay. Did you change the coolant by any chance? The coolant fogs really bad on the blue tube on this model and it looks like a bad CRT.

Samsung HC-P4752W 47" projection TV distortion & yellow?


I think you have a fault on the chroma board and on the picture frame board. If you can trace it yourself try these two locations otherwise call out a competant technician. hope this helps.
