20 Most Recent Akai PT5598HD 55" Rear Projection HDTV-Ready Television - Page 2 Questions & Answers

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.

sounds like your convergence board has failed ...there may be a kit at tvrepairparts.com..there you can search your model number for a convergence repair kit...you will need to have someone with electronics repair experience install the parts if you do not know how yourself...these kits range from 40.00 to 100.00 and usually come with a cd or dvd to aide in installing these components.

check your leads are pushed in properley especially your scart leads

Try website like Remotes.com to buy an exact same as ur original remote or very close to it. From $30 to $40 dollars plus shipping depend how rare is ur orginal remote are.Best prices my opinion.Universal remote control have very limitations and codes programming is a head aches.

You are going to have to look for open PICO fuses along with bad bias resistors close to the ic's. You should have close to +27 and -27 volts of B+ on the chips to start with. That will ensure the fuses are good. Then trouble shoot the convergence circuit from there.

Do not panic! Do not throw your TV away like I wanted to! Here is whatmay be the solution for most of the members who have posted theircomplaints here recently. I am not an expert, but I followed all blogsfrom various websites and forums, and the conclusion wasthe same;replace the convergence board for this model. I purchasedit from www.partstore.com and since this Akai is the same model asa comparable Samsung Model, buy the Samsung comparable Convergence boardfor $77. It came to about $85 after shipping. Call them if you need theexact model #. The Convergence board has two black STK ICs and twocolors of wires, a gray kind and a blue kind,all which have 'pins' andcan easily be unplugged from the circuit boardin the TV. It is basically a complete system that takes less than30minutes to install. It is a simple swap procedure, with no soldering.Youonly need the new board and a screwdriver! Remove thel ower backboard ofyour TV where the cables are plugged in (do not unscrew all the screwsfor the screen, as it is unnecessary, and might just damage your screenif you are not careful.) It has a u-like shape and comes off easy.Detach the gray wires connecting your old board to the rest of thecircuitry, and detach the blue wires connecting the old board to thecircuitry. On the old board, there are connectors marked,from left,blue, green and red. Detach those from the old board, and mark the wiresso that you may connect the correct the wires to the new board. You thenunscrew the only screw connecting the board to the TV,and unhook theboard from the TV. Hook the new board to the hooks which held the oldboard, and screw the lone screw to the board. Plug the gray cables fromthe new board to the connectors where the gray cables from the old boardwere,and do so for the blue cables. Connect the multicolored cables tothe blue, green and red, just as was done on the old board. Reattach thecover and test the TV. Please do not replace the two STK ICs only. WhenI removed my old board, I realized that there was a burn mark, where theICs were, but maybe it was a fuse.You may replace the ICs only todiscover that it was another problem.Good luck, and I wish you all thebest in the repairs. I just savedabout$100 for a repairman just to showup.

On the power supply board is a tyrisitor and high voltage capacitors 2k most of the time Poor Solder Connection right where AC line connects,you will see it on that board.
Resolder everything and set should come on.

Hi,
Is it Akai PT-5598HD tv as PT5508HD is invalid model number.
Regarding sound in speakers, go to menu and make sure tv speakers are On/ Enable
If tv speaker option is On but still no sound then unplug tv from wall socket for minute to get it reset, replug back in and turn it On and check.
Still problem not solved then connect amplifier/ receiver in TV Monitor/ Sound output RCA jacks to get tv sound in receiver speakers, this will confirm that sound processor is working but sound amplifier chip in tv is not working for some reason, replace sound output IC to get sound in tv speakers, sound output chip replacement is job of tv repairman as soldering work is involve.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

it will show you in your owners manual or in the menu portion on your TV. Remember you only have about 15% ability to do this and the tech has the rest in his ability to adjust.

yes but you will need a vidoe input to see it on the screen also you need to choose a channel to setup on.

needs a new lamp...just replaced mine with the same symtoms as yours and its like brand new now..good luck!

The tv have a problems known as a convergence problems,it dead.Yes,try website like Tvrepairworld.com to buy a whole rebuild convergence board for the replacement.The Akai/Samsung use the same tv convergence board.The board around $200.
