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 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.

    My convergence board died in my PT5598HD.... so I snooped around in the back room with my old AKIA 42" model PT4298HD.... amazing... the convergence boards are the same. The 42" was dead for other unknown reasons... but the 55 is back in action... took me longer to pull the back panel off the TV then id did to replace the unit... THANK YOU!

Hitachi 42" plasma 4 yrs old

I have the 55HDS52 and it flickered like crazy. The firmware was V0101.0001 and I called Circuit City and they sent a tech out with the latest fimware for my TV which is V0102.0001 and now the flicker is gone. I kept my settings all the same and watched the same reference scenes over and over and could not get it to flicker anymore. I'll post if anything changes but it seems that this worked for me. please have a look at THIS very long forum on Hitachi Plasma Noise

I have a 20 year old honeywell quartz air/heating control. I'm not really sure how to use the heater. It has two separate toggles at the top (one blue and one red), a button that you push "up" at the...

The Blue knob is for cooling the red for heating. I would reccomend replacing it due to the fact the age and it probably has yrs of dust built up on the mercury bulbs which can throw the tempurature off. Dust on these old mecury style thermostats is its worst enemy. The bulb is very sensitve and enough dust can throw the bulb of several degrees.

Whirlpool refrig side by side

flickering noises??? are they working at all. or are tehy flickering on/off along with the noiise. id be willling to bet that if you removed the back panel from behind the refrig, youll find a control board mounted on the left side(when lookin at from behind) alongside the compresssor assy in a white box. if thats the case that, that there is a board there and your lights are not functioning and you hear "chattering" when the doors open you have a faulty board, look up via model number and replace it
