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

1 Answer

AKAI PT5598HD The TV has a ghost image of different colors. There is also a couple of bowed lines on top of the screen. The middle of the screen is perfectly focused but as you move sideways (both directions) you start to see double images. I tried auto focus, manual focus and all other adjustments on the menu but without any success.

Your set has what is know as "convergence problem" because of the bowed lines and ghost in different colors,is really not an easy solution,the set should have 3 amplifiers(one for each color)and they need to be replaced with an exact replacement,sometimes just by replacing them the aligment should be close but soemtimes you nned to get into the service menu to do some adjustments,the amps(IC's) are mounted on heat sinks and all 3 have the same part number on its face,they normally read STK--- ---,every set uses different amps,If you are familiar with tv service you have now a place to start working but if you are not too familiar be safe and call for help from a servicer.Let Us know if you need more information.

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Check the cables, connectors and connections.

this is a convergence issue. it is caused by one of three things
1. a bad convergence board
2. a bad fuse feeding the convergence circut
3. a bad relay feeding the convergence circut

whatever the one it is they all have the same result, an inoperative convergence curcut. needs service .

if it is still under warranty, great. If not the parts can cost up to $300 and labor can be the same

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


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,Pioneer2_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...

*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

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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
