My tv is a magnavox and we bought it about 3 years ago and it is now showing like a double picture the color is hazy and pinkish looking the model is 51MP392H/17


The problem of your unit is the convergence. Try to adjust it using the original remote control in the setting menu, then goto the convergence section adjust the red and blue convergence, you should move red and blue UP, DOWN and LEFT or RIGHT, if you cannot move them far enough the convergence IC is defective, replacing this IC will restore the original setting of your tv. This convergence IC is attach to a large aluminum plate it is the heat sink this IC has a marking of STK-#### followed by numbers, remember be careful when replacing this IC you may accidentally tampered or damage the PCB and cause much damage to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards. Try to check this link for the convergence http://www.google.com.ph/search?q=convergence+ic&hl=tl&sa=X&tbm=isch&prmd=ivns&bav=on.2,or.r_gc.r_pw.&biw=798&bih=472&ech=1&psi=JZdtTvDCPIe4iAe72sTABA.1315804977740.3&emsg=NCSR&noj=1&ei=MpdtTpa4OKKSiQfBpcjGBA

Green & Blue Ghosting Convergance problem


Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.

Did you replaced 2 IC convergence as well or just 2 resitors 3.9 ohms ? if you did replaced 2 IC then you might have probelm in convergence drive it is1 of the PCB mount vertical on the left side from the rear view under part BP95-00415C you need to readjust the convergence by using your remote control just follow in the servive manual

I have a 65 inch toshiba projection tv about 5 years old that has a problem with the picture. the red blue and green lines are not aligning, giving it a 3d looking image. i was just wondering what it might...


Greetings fireftr2001,

You may need to perform convergence on the unit. This is something that needs to be done periodically and especially if you have recently moved the unit. You can normally find the convergence option in your menu system.

Thanks,

Resetting convergence daily on Toshiba 43h70


Hi Mark, tough call without putting a scope to the circuit, either the convergence IC`s are going bad, signal from DCU is going bad (digital convergence unit), or possibly bad solder somewhere in the convergence circuit, I`m afraid your going to need a tv tech for that problem, BMW Rider

How to do convergence on a PT-53WX53


Hello Yann,
Please be advised that doing the convergence in service mode is a very complicated process. This could mess up your TV even more. The best TV tech out there finds doing convergence a Headache. Doing convergence is part of the repair that most TV tech fears. Email me if you still want it. I will not post here for the general public.

Best regards

Pioneer rear projection 51inch tv


moving big screens around may throw off the convergence, look to see if you have red,blue or green or all.. ghosts or edges in the picture. you will need a tech manual ..not owners manual to fix it, I would call a local tech and hear what he thinks for just a service charge. good luck
