Akai PT5598HD 55" Rear Projection HDTV-Ready Television - Answered Questions & Fixed issues

T'Con board fault. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

Its a DLP that uses a lamp, lamp is possible but I would also look to see if fans are on and running, a fan stopping or even slowing down can trigger the set off also.Average lamp life is 2000 hours or two years and set if lamp a bit dim may shut set off.

Replace the convergence amp board and that should solve the issue.

In the customer menu first look for convergence--if this is Akai it is made by Samsung.in the convergence menu will be either a grid of lines or several crosses--examine and see if your red line is out of position there.If it is it may just require with the remote adjustment in that menu.Cleaning will not resolve a red line.let me know what you find.

send a email to customerservice@tvrepairworld,com they can assist with diagnosis.

jreneaua44,

Replace the main board. I have a tip at http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs for help.

Thanks for using FixYa and for the great rating.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Replace R858 and R859...They also go bad frequently when the STK chips fail.

For everyone else...

SOLUTION

You can get the correct parts, step by step photo instruction guides, and support from www.TvRepairKits.com or click here

If the perfect focus isnt working its caused by failed convergence. You can get the convergence board from www.tvrepairworld.com its under the Samsung / Akai circuit boards.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Sorry this problems u describing it is not good.The tv having a buzzing sound mean the tv FBT-flyback tranformer is dead and it is not giving the tv anymore high voltages to the tv screen.Also the deflection circuitries board have some dead components too.Sorry can't give u a price,because this tv have to get an estamate prices by a tvs tech. and trouble shoot major sections of the tv circuitries and replacing parts.It vary from shops to shops.Must call many tvs shops get an estamate and compair prices.

The television has Dual HDTV component-video inputs. Not HDMI but a lower level HD input.

Make sure it's plugged in.

the reason this is because the convergence needs set these tvs should be serviced ever 3 years or so this is definitely the problem i fix these all the time a good tv repair man will do it for under 120 pounds and its worth it your tv isn't broken don't worry the convergence settings are adjusted by dials in the back of the tv inside the case its not for a user to do it will just become worse id advise to have it done and it will be like new again and the person will provide a warranty and a good tip is maybe 2 years after give it a shake and hell have to fix it on warranty covering you for another 3 years of viewing if you don't believe me do a search and ull find out please make sure and make the payment for my help thanks and good luck any more questions don't hesitate in contacting me

check you bulbs they may need replacing and your speaker wires may be wore out

The tv problem is call convergence problems,it dead.Tv have convergence colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts must replaced on the tv convergence board to solved the tv picture convergence problems.Try website like Tvrepairworld.com might still can buy a whole refurbish convergence board for the replacement.The Akai and Samsung DLP tvs used the same convergence board.Or the shop,will cost u like $300-350 for parts and labors.

Hi,

Ok, you probably have a failing convergence stage. This is very very common in older projection TVs like yours - maybe the #1 problem.

The TV has three color tubes in the lower half of the cabinet that project an image off the main mirror and onto the back of the screen. The convergence board processes the signals to the tubes and adjusts the light beams so that the red, blue and green images all line up. When the board fails, the light beams don't line up and you get the '3D' image with the separated colors and bowing near the edges.

The board has two main components called convergence amplifiers (some call them STKs or convergence ICs). They can fail. It is also common for some pico fuses or fusible resistors on the board to pop. If all three colors are off, then the STKs are probably bad. If only one color is off, then it could just be a pico fuse or other small component in the signal path.

You have three choices.

1. Some people have fixed the board themselves but it is not a job for a beginner. The parts are only about $70 but you need to know what you are doing. I can point you in the right direction but you need to have a good understanding of soldering and troubleshooting basic electronic components. You would need a DMM and soldering tools. Here is what is involved - it will give you an idea: http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html

You can buy the kit for your TV here: www.tvrepairkits.com

2. You can try and find a rebuilt board. This would probably cost around $300 and you would need to pull the old one out and put the new one in.

3. You can have it professionally repaired. This would probably cost around $400-$550

I'm sorry it isn't the best news.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

all in one day my screen started by showing a u look at top and bottom. all three colors kind of separated from each other and therefore made shadows on all the writing and double and triple vision on people and images. then it drawed in from sides and showed some black. then it popped in the back and no picture. the sound then came back on with no picture. so i shut it off and unplugged it. what do i have to get to fix this? thank you, Robert Hopkins

the 3 tubes inside can have enough dust on them to make it dim. but with this set it is caused by age. you are better off to put you money in a new set.
