Question about Akai PT4298HD Rear Projection Television

1 Answer

Hourglass shaped red

After 2 years I turned on my Akai PT4298HD and the projected blue coloring was shaped like an hour glass on its side. Red and green were fine. I tried to manually adjust convergence (assuming that might be the problem) but it had no affect on the shape of the blue pattern. Can someone tell me what this might be ?

Seeing double image in three colors


Its a convergence problem for sure ,,,if you cant move the red or blue (green is stationary) then your problem lies on the convervence module.. requiring ....mostly new output ICs like STKs your going to need a tech, for convergence is a common problem with rear projectors and requires patience and a expert to get it back just right. good luck

Tv picture shaped like hour glass


The link you posted has been deleted, so I cannot see the picture you posted. If the sides bow in like an hourglass and the red, green and blue colors are still aligned then there is a horizontal width or pincussion problem, but if the sides bow in and the 3 colors have separated and are no longer anywhere near aligned then you have a convergence problem, both of which should be serviced by someone with experience in servicing projection TV's.

If you have a good picture except for a missing color all the various circuits are working OK. Most likely you have a bad solder joint or component in the red circuit. This would also be indicated by the fact that ocassionaly the red pops in. If you have the experience remove the boards and inspect for cracked or cold solder joints. Resolder anything that looks suspicious. If this does not fix it you will have to troubleshoot the red drive circuits from the CRT back to the video IC. Another possibility is that you have a bad/intermitant red crt. I doubt that you have the equipment to check this but you can test it by moving the green crt board to the red crt. If it now works the red crt is OK. If all this fails you will need to find a reputable repair shop to look at it. If the unit is more than 5 years old it may not be worth fixing. Good luck.
