I was just given a samsung hcp4752wx/xaa. The blue picture didn't line up with the other colors creating a double image. The previous owner took set apart and opened the blue lens dumping the fluid out. first can you clean the lens and replace the fluid or is it just junk and what caused the original problem? Thanks, Matt

    where can I get the convergence chip, and can I replace the fluid in the lens? The tv is just for the basement to get the kids out of the living room. Thanks for the help, Matt

OK, Its always best to replace the lens assembly if its not preforming well. never dump the fluid. just replace the lens. As for the double images and the misalignment of the blue convergence line, this is caused by a faulty convergence chip that is located on the convergence board. you will need to replace this board in order to restore proper convergence performance.

    hi, the individual chips are not available at this time. they have been discontinued but, you can order a refurbished board with the chips already on it. use the Link below to order the replacement conver board.

    concerning the lens. it is good practice to just discard the old lens and purchase a new lens that is pre filled. we do not recommend refilling the lens cavity.

I have a Samsung Hlr5667wax/xaa DLP TV and the screen has gone green/green plaid pattern.

when the color wheel stops the picture will be all over the place. and you will have lines when it starts to fail as its not going fast enough for the picture. wining sound is it wearing out.

I have a samsung hlp6163wx/xaa I replaced ballast and bulb. Color wheel sounds good but just a dark blue picture and perfect sound what could it be?

Some things to be aware of here--if the color wheel turns too slow set will shut down---if you hear a fan like or high pitched sound it is the wheel.

If a uniform blue and dark it is likely the DMD which is the box the wheel connects into and can be purchased by itself (forget that as for about 50 more than it costs you can buy the entire light engine that comes with it)

Bottom line: Likely a bad or damaged optical light engine.

I recently had my tv repaired for diode problem,it is a samsung LNT4066FX/XAA flat screen.Now instead of clicking sound and not turning on the power bar at bottom stays blue and the picture has color...

Well the capacitor problem usually causes power up problems. If your tv comes on now it sounds like you dont have the same problem.Vertical lines are usually caused by bad flat panel or dirty ribbon cable contacts on flat panel connections.

Sound like one of two things: A test screen, or a broken TV. More likely than not, your television is broken. Try hitting TV/Video on your remote, and if that doesn't work, power the TV off, unplug it, and plug it back in. If none of the works, it's time to call a repair man.

Used samsumng hcp4752wx/xaa is showing triple vision

Not too familiar with this exact model but am very familiar with Samsung DLP. If this is a Rear Projection (3 CRT's R.G.B.) it is surely the convergence chips ($12 each X 3). If this is a DLP (Color Wheel @ 7000rpm) this is not good news as a DMD board for Samsung DLP is around $400 (not retail either, warranty part price).
