I have proscan 56'projection tv when turn on only have sound and close caption no picture Please some one help1!!! thank you.


check the video connection that is connected to the tv. If you are using RCA style plugs (red, white, and yellow) you can try swapping the colors around (put the red in the white, the yellow in the red, and the white in the yellow on the tv and your other device....cable box, vcr, dvd, etc.) this is a great way to test the cable you are using to send video to the tv. it might just be the cable!

No sound no picture went blank .


Do not panic! Do not throw your TV away like I wanted to! Here is what may be the solution for most of the members who have posted their complaints here recently. I am not an expert, but I followed all blogs from various websites and forums, and the conclusion was the same;replace the convergence board for this model. I purchased it from www.partstore.com and since this Akai is the same model asa comparable Samsung Model, buy the Samsung comparable Convergence board for $77. It came to about $85 after shipping. Call them if you need the exact model #. The Convergence board has two black STK ICs and two colors of wires, a gray kind and a blue kind,all which have 'pins' and can easily be unplugged from the circuit board in the TV. It is basically a complete system that takes less than 30 minutes to install. It is a simple swap procedure, with no soldering.You only need the new board and a screwdriver! Remove the lower backboard of your TV where the cables are plugged in (do not unscrew all the screws for the screen, as it is unnecessary, and might just damage your screen if you are not careful.) It has a u-like shape and comes off easy.Detach the gray wires connecting your old board to the rest of the circuitry, and detach the blue wires connecting the old board to the circuitry. On the old board, there are connectors marked,from left,blue, green and red. Detach those from the old board, and mark the wires so that you may connect the correct the wires to the new board. You then unscrew the only screw connecting the board to the TV,and unhook the board from the TV. Hook the new board to the hooks which held the old board, and screw the lone screw to the board. Plug the gray cables from the new board to the connectors where the gray cables from the old board were,and do so for the blue cables. Connect the multicolored cables to the blue, green and red, just as was done on the old board. Reattach the cover and test the TV. Please do not replace the two STK ICs only. When I removed my old board, I realized that there was a burn mark, where the ICs were, but maybe it was a fuse.You may replace the ICs only to discover that it was another problem.Good luck, and I wish you all the best in the repairs. I just saved about$100 for a repairman just to show up.

Proscan Model PS60680 Will not power up. It would sometimes work if I unplugged TV and plugged back in. Sometimes I would get 25% of the screen with different colors, now it is mostly blank with occasional...


You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

Sound Problems ProScan 61" Model#PS61670


A technician here suggested that I unplug any VHS or CD player as this could cause it. After doing this I had the TV on for about 4 hrs and didn't have any trouble. So far so good. Thanks for checking on me. I really like your Web page it's most helpful.
