Akai 5598hdi convengence

Hi sreekidu, 1st of all thks so much 4 helping out all of us who cant afford the in person repairman. I have an akai 5598hdi. like to many other buyers, I have a contengency prob also. I bought 2 amps and replaced the old one refer:( cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html ) after the replacement/heat sink, i turned on the tv w/no results.. I was unable to do manual adjustment what so ever. I then called samsung and asked for the replacement board..they said they discontinued that board for the akai.I then asked that if so many people are having the same prob after 3-4 yrs, why would you discontinue the board? well after a bit they set me up w/J&J Inernational,Inc they had a replacement board BP95-00142E w/2 ic's stk for $96.00. Well i greatly thanked them and ordered the part..I get the board and replace the old one and still I'm unable to adjust the convergence manualy or auto... the tv remains the same as before. Am i forgetting something or is there a process? I have no svc manual and figure I've spent enough on the tv.. Pls help if u can... Happy Holidays.. email if needed:banditlee07@yahoo.com...many thks bandit

    Thks troylove11 for the help,if I had replaced the board w/a new one,should'nt all the fuses be good 2 go? you said(fuses open in that area)or do u mean fuses in other areas of the tv? My contengency board is a newly seperate standalone board. Its just wierd doing these changes/replacements and i cant adjust anything..thks again...

  • ted lee sweitzer Dec 26, 2007

    can anyone pls snd me the adjustment codes or svc manual pages under contengency. If I had done a factory reset on my akai some say the new contengency settings must be installed in the mem ..How do I do this and Thk you all for the help.. Bandit

    Thks Terryfic, My contengence board sets seperatly by a single screw above the main cir brd. The one I ordered was complete w/the two amps attatched. I just disconnected the old one and replaced it w/the new. The description as listed on the invoice:(J&J International, Inc): ASSY SUB PCB-CG AMP/WITH 2 IC'S STK: PART NUMBER BP95-00142E. COST $96.53.Reading most fixs here, they say they replaced the boards/stk's and did a manual adj.. I'm not able to do this so i assumed there is something Im not doing... most said code mute 183,adjust then save.. but nothing happens in my case. when attempting perfect focas i get (check factory data) oh after replaceing the new brd and no results, I did factory reset. hope this info helps .. well let me know I'm stumped... thks again Bandit

The B+ voltages to run the convergence originate on the main PC board,power supply area...there are soldered in fuses to be
checked with an ohmmeter.....another related procedure is to
measure voltages with a meter, but that is normally done by
a qualified tech with service manual in hand..............T.

    Bandit,

    I verified PC board correct for your model, but I have a ?...

    What does " A REPLACEMENT BOARD ...W/ 2 IC'S..."

    mean ? Were the IC's seperate from the board or already mounted on the board ? What quality...? ..brand....?

    warranty....?......................................T.

  • Vista Electronics Jan 02, 2008

    Bandit,

    Service entry is with power off....mute 1-8-3-power on...adjust

    and save.....And I never do factory reset,usually means get the

    service lit. so you understand what to do step-by-step.....T.

  • Vista Electronics Jan 04, 2008

    Time to get the service literature....try

    manuals.electromaniacs.com ..................T.

  • Vista Electronics Jan 04, 2008

    Try.............retrevo.com servicemanuals.net ForFinds.com

    ....................T.

    I still think it is BEST to install PANASONIC IC's.....I use them

    for STK392-040 in whatever brand I am repairing........You could

    rebuild your original board with..Part # C5AA00000107......about

    $30.00 each....if it works you could send the new circuit board

    back for defective refund...........T.

When amps go bad most of the time they cause fuses to open in that area. They also will need return resistors replaced. Unless you have done all of this then, you should not replace with new ones, it will only damage them also. You may need schematic to find the fuses and resistors.

    You will definately need the old codes before erasing what is on your EEprom in set. I don't have a list of this but if you get it I can assist.
