Question about Akai PT5598HD 55" Rear Projection HDTV-Ready Television

1 Answer

AKAI Rear Projection TV PT5598HDIX has sound but no picture

The red convergence was way off, so replaced the two convergence IDs (STK392-040). Now the TV has sound but no picture: the three bulbs to not light up when the set is on.

    Hi Doctor Video.
    I checked for bridged solder connections with a continuity checker. Found 5 pico fuses - all good. All connections seem to be ok. I appreciate your help: any other thoughts on why the three bulbs would quit working after replacing the convergence ICs?

    I too just went through the same repair. I even replaced the whole PCB board with a new one I ordered and my TV still has sound and no picture. Any other ideas on what we could have knocked out by replacing these items. Thanks

Red, Green convergence lines are wavy


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Akai 55


I used" Silerado 1st" solution. I have an Akai pt5598hdix/sms.
I had ghosting.Like 3 colors side by side.
Silerado said with TV off press "mute,1,8,2" then TV on.
I didn't see anything like a menu.He warned to write down any setting you saw before you change anything.But for me nothing came up. So as he said the next step try with TV "on" press "Mute,1,8,3" this is another set of adjustments for finer detail. I lined/overlapped all the lines up or down or side to side useing the channel and the volume buttons and then held the enter button down until the TV flashed 3 times.Then I shut it off and when I turned it back on It was perfect.

Picture is suddenly "bowed" and the convergence is askewed at everypoint but center.


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.
