SOURCE: Green "halo" around the bright white images

I have a Samsung HCM5535W rear projection TV that had pretty much the exact same problem-- a green halo around bright white images. I researched it on the net, and determined the most likely problem was with the convergence STK-ICs, or the convergence board. I bought a replacement board with the STK ICs and installed it, but no luck, the problem persisted. I decided to mess with the manual focus adjustment on the green crt (i was seeing a green halo), and that fixed it. As it turns out, no replacement parts were necessary to fix the problem in the first place. Hope this helps somebody out there.

Ok try turning the tv of for 40 minutes by the power point and back on. that way it will reset picture - and should go back to normal please let me now how this goes ((By a rating

Make sure you un plugged it by the power point for the 40 minutes
also make sure there is no speakers or anything magnetic within 60cm's of the tv this can also cause the picture to have strange colors in the screen - if that happens simple do the above

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

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!

Mitsubishi WS-65511 Rear Projection Big Box TV resets with a green flashing light every 5 minutes, Then works fine for 5 more minutes (perfect picture). Acts up worse when cold. Warm it up Works hours It's NOT the DM board caps. I've already replaced the DM caps twice. Not the problem. No repairman will look at the set. Too Old. So am I. I could repair it with help. The power supply must have a safety circuit that will shut down & reset if too much draw. I DON'T have a diagram. I'm not sure how to trace it . Which board? If I unplug boards one at a time, Will it damage other boards ? I know it is NOT the 7 DM board caps everyone keeps telling me. I see no burn't parts, No bulging caps. Tapping on components doesn't reset. What kind of component would act up when cold , But not overdraw when warm? This set has the best beautiful picture when it runs. If you can get past the resetting every 5 minutes for the first hour, You can watch it sometimes for 20 hours. I've left it on at night & it is still on the next morning. Change the channel Or raise the volume, And off it goes. Once or 10 times, Keeps resetting. Then on for 4 or more hours, Maybe. I can't afford a new one. It works GREAT ! when it works. I've notice that even when the set is turned off, The green light starts flashing (resetting itself while it's off) , Then stops. Once in a hundred times it will kick off the breaker & you need to push reset with a pin on the front panel next to the green light. It's probably a 10 cent resistor OR a $ 1.00 cap. If I only had someone with more knowledge than me to help. I know how to use a meter & read a schematic. I built a Heathkit 25"TV in the 70's & all my novice ham gear. I'm 64 & not familiar with digital circuits. Can someone help PLEASE ?
