Question about Samsung HCM4215W 42" Rear Projection Television

HCM4215W Green convergence problem

On my Sanyo TV the green convergence is out of whack. The verticle green line when adjusting auto focus is bowed no straight. You can adjust it on at the top and bottom, but its WAY off in the middle. The red and blue look OK. I Have the service manual for it, but no experiance with rear projection and don't want to put much into it.
Thanks
Greg

Hi Greg,
Sounds like you have a bad convergence chip in the convergence board. Unfortunatly, about 80% of the rear projection sets I work on have this similar problem. I suggest that you change both chips ( there are 2 of the same ) and remember to use heat sink compound as this is why you not have the problem ( excessive heat destoys electronic components). Good Luck

Green verticle line on right side of image


Your color convergence is out of adjustment. You can adjust yourself with a service manual telling you how, or take it to service shop and pay about $400.

Mitsubishi Convergence issue


If the screen is out of focus you probably need to adjust the focus on the focus block it is usually located behind the front grill, there are 6 adjustment screws on this block, leave the screen controls along just adjust the red, green, and blue focus screws. When converging a set everything is converged to the green, the blue and red are suppose to come to the green.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Hitachi 43FDX01B green is out of whack


The green is not adjustable in the customer menu because it is considered the 'master' color. It is adjustable in the technician mode however but if it is curved it won't even adjust properly that way either. The problem is the convergence ampifier responsible for green convergence has failed. The convergence output IC's need to be replaced.

Is there a manual convergance on 53udx10b


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.
