Question about Akai PT5492S 54" Rear Projection Television

2 Answers

PT5598hdi This morning there was a click while watching tv and I suddenly had ghosting, bow tie effect and 2 stripes of color on each side. Looking at the site I figued it was the convergence ICs. Took out the board and still had the same effect. I had 2 new ICs replaced and brought the board home. Put the board in and only had sound. The screen is blank. Turned the tv off and unplugged it. Plugged it back in and now I have just blinking of the red light between 7-10 times and then nothing. Last year I also had the board and power supply replaced. I just spent the last bit of money I have! Great huh. Just my luck. Is there anything I could try now. Thank you kindly for your time all of the sudden I have the same type of problem I think. looks like everything is in 3D. the bowtie effect is going on. I really can't afford to have this fixed. What should I do. Is it just some type of setting or should I just trash the damn thing?

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,PioneerPT5598hdi - 2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

Akai PT5598HDI Rear Screen Projection TV With Blue Shadowing


If the ghosting is like a 3D effect its your convergence ICs , but if its like a blue Halo around objects that usually means your CRT coolant has congealed and will need replacement. The blue is the first tube to congeal for some reason, followed by green. Red seems to be not quite as prone to this. It is a normal occurrence n sets about 4 years old to need the coolant changed.

AKAI PT5598HDI Colors out of line and picture is bowed in on bottom and top.


http://www.fixya.com/support/t1663670-akai_samsung_pt4299hd_convergence Adjust the convergence manually. It's a pain and takes alot of patience. The diagram for the remote buttons helps a lot. If it won't adjust you'll have to replace a part inside the tv. Good luck! Hopefully it'll adjust.

Bow tie looking picture with 3d color mis-alignment


you have lost convergence. First thing to check is to see if you are missing the convergence option in the customer setup menu. if you do not have this option then i suggest reading the article in the tips and tricks section entiltled "the fl231 fuse problem" this is a common and sometime easy repair if you do have it then you might need a convergence power board

the problem is the EW cicuit of the deflection cicuit. this is a component level repair call a tech. the EW or East West correction is apart of the horizontal deflection. IC431 is the pin amp.

Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture


The convergence ICs probably have a cracked solder joint on the foil side of the circuit board. Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. To fix this yourself, you will need to be able to identify the two convergence ICs, have a basic knowledge of electronics and be able to use a soldering iron. You will also have to do an alignment through the service menu.
