Rear Projection TV convergence

That depends... It is normal for a rear projection TV or monitor to slowly drift slightly out of convergence as the CRTs age. If any sudden drastic change has happened the there has been a component failure on the convergence board. Usually it's the large ICs and maybe some caps and low wattage resistors as well. If the TV has just slightly drifted, there should be a large amount of controls on the convergence board which can be adjusted, or it may be done through the menu, depending on the model. If it's done by controls, most manufacturers attach a long extension cable to the convergence control board so you can stand far back from the screen while adjusting all the controls.

Hi Kelly,

Some of the older units have a slide out convergence PCB with a load of pots. These are a real PIA but after a bit of practice you can get good results. The more modern units use a remote control (usually lost by the arcade center) that you use to converge. What ever you do never reset the storage data (some have no warning) as it will take ages to re-align the screen all square again.

What chassis and games do you have? I have access to most Mitsubishi and Toshiba service info.

thanks Wes, i will look up model #'s tonight! i have 3 games with 50 inchers in them.....Virtua Cop, Alpine Racer, and a Time Crisis.

i don't remember seeing any satelite/remote board hanging around but will check again. all these came out in mid 90's(94-96 i believe)!

thanks for the posts,

Kelly

If it's pots it takes practice...with the remote, once you get the idea what is being asked of you, it can be a fairly smooth ride. JVC even offered customer convergence adjustments in their sets a few years back. Good luck.
