Question about Samsung HCM4215W 42" Rear Projection Television

2 Answers

Picture issues, not sure what the problem is, photos posted

My last post had the wrong email, etc. Have had this television for the past 4 years, just suddenly had issues with the picture that can't be solved. Convergence doesn't work, similar issues no matter the channel, etc. I have attached photos that may help with diagnosis and if someone else has seen something similar. I am thinking this might be the convergence module for the easist fix. I looked and don't see a good resource for getting this part, does anyone have any leads as well as part numbers? thanks... jeremy

It looks to me like the green is sagging down at the top, and this means that one of your convergence IC's has stopped working. Instead of replacing the whole module, locate the convergence IC (Samsung typically uses the STK392-040 IC's) that handles Green Vertical (GV) and replace it. Sometimes there is a fuse next to the IC that looks like a small resistor that opens up too. If you do not have experience changing convergence than have a qualified tech handle it for you.

Mitsubishi dlp dark in the courner

To begin with remove lamp and make sure nothing happened there as if the light is partly obstructed it could cause this

You can post a photo here or contact and email them the photo to forward to me.


I worked on a lot of these sets when they were new but do not think I have seen or heard of a issue quite like this---too odd it happened shortly after a lamp was replaced.

By the way I am sure you know or knew not to touch the face of the lamp with your fingers.

Picture is warping and colors are seperating giving a picture that looks like a 3D picture without the glasses

you need to replace both convergence Ics. Post the model number of your set and I will post the correct IC numbers as well as alink where you can get replacements with free instalation instructions. Respond to this same post so I will have access to your symptoms when you post the nodel number.

MISTUBISHI VS-50501A - top 3/4 of screen displays ok, rest does not

Check the vertcle yoke pins for solder cracks. Check verticle output circuitry resistors and transistors. And also check for Coolant leaks from the CRTs this happens alot. Check capacitors for any signs of sweeling or heat as well.
