This is a bad vertical section. Probably just capacitor(s), but it will require repair.

    If you are good at soldering and can figure out where it is located on the board without a schematic, or have a schematic, then it's not that tough. The capacitor in question is the in the vertical retrace path. Usually, it is in the feedback loop. It starts to leak and allows dc to pass, reducing the retrace voltage, and thuse the amount of deflection of the beams. This results in a smaller picture, top to bottom.



    If you're scared now, I understand. A tech can easily fix this and a projection TV is most likely worth the effort and money unless it is too old.

Samsung HL-R5688W DLP TV Screen Burn


I don't know where you got the information that burning could not happen but that is completely wrong. If it is a monitor, tube tv, LCD/LED, DLP or any other kind of viewing device it can burn. With that out of the way if the lamp warning is coming on then it is time to replace it but your image problems are deeper than that. The screen appears to be separating. By that I mean there are three layers and sometimes more depending on the manufacturer that display color. Think of it like saran wrap laired on top of each other. As they get old or of poor quality they start to separate and show some pretty funky imaging. Without the TV in my shop I most certainly cannot 100 percent say for sure that this is it but I would strongly consider this as not fixable.

My room mate spilled his drink and a little went on the bottom left corner. i dried up as much as possible, but now there is a dark shadow spot on the screen in the bottom left. how do i remove the screen...


liquid is never good on those screens-
there are 3 layers to the screen, from inside out, a fresnel screen (etched circle pattern), a lenticular screen (ridge lines top to bottom), and a protective screen ( "Diamond Shield" tinted plexiglass).

the fluid will wick up btween these layers, turn black, then very very slowly recede leaving a waterline mark. It can take months for it to become un-noticeable.

cleaning is possible, but beware, any type of cleaning fluid or spray is going to simulate the exact same problem but to a larger area.
also introducing dust, lint or hair into the layers when separated is almost impossible to avoid.

these pieces, especially the lenticular screen are extremely fragile nylon plastic and is apt to split under its own weight when handling, so beware the project you are about to get involved in...considering the large size.

but it can be done.
Remove all screws around the screen frame from the back of TV and the lower sides. There will be a wiring harness that goes to front buttons- disconnect it. The whole assembly will come off the front of the TV.
Lay it on the floor face down. Remove the screws in around the inside of the screen. The screens are now ready to lift out, one at a time.
IT IS IMPORTANT to not attempt this by yourself. The screen are fragile and large and scratch so easily which appear as a white opaque area when reassembled. Have a helper. Wear cotton gloves while handling as finger prints will be noticeable after you reassemble.
ALSO IMPORTANT- these screen are oriented front and back...in other words they go together in a certain direction...on each screen layer there is a small sticker on its outer edge. Make note of its orientation and reassemble accordingly.
Clean with a cotton cloth and very very little "plastic glass gleaner" (if needed only!).
WIPE EXTREMELY GENTLY in the direction of the grooves on each screen layer- much like cleaning an old vinyl record.
The lenticular screen is the biggest worry as rubbing on the grooved side is so likely to cause damage. Perhaps rubbing should be avoided if possible.
Let them lay out and dry before reassembling. A bottle of compressed air is good to remove debris when layering them back together...a dust free environment is recommended.
Reassembly and installation is just the reverse of dis assembly- remember the wiring harness connector!

It works & sounds great but there is a curve at top & bottom of screen where color is off and there is a double image in that area


Good Day,

This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem.
If you want to repair this concern yourself: Contact: B&D ENTERPRISES,
1-800-458-6053, www.bdent.com and ask for KIT10 for your Hitachi TV. It will include what parts are needed and where tey are located.
If you want some else to do the repair for you call an Authorized Service Center. Cost around $450.

Good Luck, big IRISH.

Screen appears curved on top and bottom


One or more colors can't be adjusted when when using the convergence menu. Screen is bowed in but stationary.

Solution: 

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.

Samsung Rear Projection TV - SP43H3HT


There is a problem with the self focus function on the TV set.  We have had ours replaced twice. Once under warranty and once out of pocket.  After you get it fixed, if you do, the self focus option needs to be set to "OFF" and only focus the TV when necessary.  Ours is going out again unfortunately. You would think paying what we all did for this paticular TV  we would or received a higher quality project.  However, Samsung only hymns and haws about it and offern absolutely no help other than TV repair people in our area that they know about. (which seem to charge absolute top price).

We tried to get the screen replaced while under warranty and were unable to Samsung wouldnt cover it.  Now we cant even locate the top layer screen and pay for it ourselves.

I dont think I will ever purchase a Samsung TV again.  Never again.
