Question about Samsung HCM4215W 42" Rear Projection Television

1 Answer

White tint/haze Not sure exactly how to describe the problem I'm having with my tv. It's kind of like a white haze on the entire screen. All three lamps seem to be working properly. One piece of information that might help diagnose the problem is that when I attempt to utilize the Perfect Focus feature, it gives me the following message at the top of the screen "No Sensor Data." Please let me know if you have an idea on what the problem is exactly. Thanks

Re: White tint/haze

Check any/ all pico fuses in power supply. PVAT! Look for evidence of CRT coolant leak. Since Perfect Focus is a function of convergence,you might consider replacing convergence IC's,then perform alignment in servicer mode,then finish w/Perfect Focus.

I have a phillips rear projection tv model no 55PP8620/79. Its showing a a red haze and poor picture quality. How do I fix this?

If the red haze is not convergence---that requires parts.

The set has three picture tubes---with set unplugged and back cover removed clean the three large lens that are topside---as for the red haze a quick way to know what is wrong is with set on turn the color to zero----what color is the screen? Should be black and white--if red to some degree tracking or screen controls may need adjusting inside the set---Yellow picture in that situation is a different issue.

I have a 60 inch Philips tv and the picture is kind of blury and a little red. What is tha caused from?

THREE possible reasons for this:
I will list each and describe for you:

1.) If redish picture go to a black and white channel; is the screen somewhat red or black and White? This is adjustable from inside the set.

2.) If colors are skewed or look like they have a red outline it may be a convergence problem. See attached photo.

3.) Some of these sets develop a problem with the coolant which is used to keep the face of each of the three tubes cool; it is called Glycol. You would have to remove back cover and with set on look into each of the three lens (red,green,blue) to see if you have a clear red, green and blue picture.

Which best describes your problem?

PICTURE PROBLEM(white hazy picture)

hi, symptom is caused by mis-adjusted focus, theres mechanical adjustment on lenses, and theres electrical on focus block, if tv was recently moved I would guess it`s mechanical, I strongly recommend you get a tech to do this, good luck video-tek.

Blue tint on rear projection tv

If this is a crts model , then one of the crts had blown, if it is a lamp rear projection, then it is a fault on the video circuit.

Blue haze spot-yellow tint

I have the same problem with blue haze that just spread out on model 55VS69A ,
tv is almost 2 years old. i called hitachi and they advised to call a local repair center to check the tv...they confirmed Optical Block (light engine ) replacement light engine cost $1400 and labour $400, so i called back hitachi and they said they will provide light engine and will have to pay labour!....this is not right paying out of pocket for a tv less than 2 years old....I am not sure if the issue will resurface again...more likely ....Hitachi is supposed to issue a recall or atleast like sony did to cover all cost for there defective TV's....I will NEVER buy hitach again.

Hitach SUCKS.

TV Image not bright enough

I'm not sure if my answer will help much, but it is free. My experieence with this site is that without paying for premium service, you won't get much help.
I had a similar problem with a different model Panasonic projection set.I got no answer on this site, but I did from an outside repairman.
Turn your color all the way down. If it looks black and white it is probably not a bulb problem. If you see a tint (blue, green, red) over the screen, it probably is a weak bulb.
The entire bottom front of my model was held on by velco and could be pulled off.
Behind this was a removable black panel. Behind this were adjustment screws for the three bulbs. This will probably only help temporarily if the bulbs continue to weaken, but it might buy you some time as the replacement bulbs are quite expensive. Good Luck
