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.

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.

When turning TV on it would click a few time, then you would hear a hissing sound, but no picture. Would have to unplug TV, as it would not power down. Unplugging and plugging in would eventually get...


The hissing sound could be high voltage leaking from a tripler. Observe in a dark room for blue arcing. Look at tripler and connections to the projection tubes. If the tripler is leaking replace the tripler.

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.
