Question about Projection Televisions
While watching tv - the colors went out of alignment with each other. What could be the issue? We have turned off and turned back on after 5 min
my rca 52 in has the same problem. but seems to not auto converge . and even when i manuel converge the screen is still looks like a 3 d movie.
i have tried every thing.. and its only a year old..
I have the exact same problem. Its showing 3 different color lines. Mine is only 2 years old. I bought it for $900 at Walmart but I kept my receipt. I called so that they could fix it but they said they dont make that model or the pieces for it I guess so Walmart issued me a check for a full refund 2 years later. On top of that, they said i could keep the 52" so now im trying to get it fixed somewhere else & get another tv. But if i get it fixed will i have the same problem again or another soon on these particular model tvs? Im trying to figure out would it be best for me to get it fixed or just spend the money on another tv?
The convergence circuit is the problem. If you can solder and are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, you can fix this yourself. First locate the convergence ICs which are large black ICs attached to a heatsink that will be marked STKxxx. Try resoldering the pins on these ICs first. If that fails to resolve the problem, replace the ICs. Please note that there could be additional small parts that require replacement as well. Start with the ICs and let me know the results.
