AKAI MODEL PDP4298ED1 BLACCKI BAR ACROSS SCREEN NO PICTURE OR SCREEN NO RF SIGNAL . R5106 IS RUNNING HOT ON THE Y BOARD WIL OPEN UP IF LEFT ON OVER 3 SECONDS. CHECKED D5027 LLEADING FROM THE R5106 RESISTR,CHECKED FOR CAPANCES ON *** COMPONETS IN THE AREA CHECKS OF BUTDO NOT HAVE EQUIPMENT TO CHECK FOR LEAKS ON TRANSISTER OR CAPACITORS. [email protected]

It appears you have one of two problems. The lines across the top may be horizontal. And you may have a black horizontal bar across the top as well. If this is the case you have a vertical IC that needs resoldered or replaced. The capacitors near and next to this vertical IC will need replaced. This would be the powersupply board. It would be the board with the the flyback transformer ( it looks like a distributor cap with four sparkplug wires coming out of it). On the other hand, if you are concerned about colored lines not lining over each other correctly. You would have convergence ICs that are bad. You will need to replace these and any low ohm (below 10 ohms) two watt resistors. Could be two or three of these that are bad. And not to discourage you...there may be two capacitors that are bad. The convergence board in this case is also the signal board. It is the one with all the RCA jacks and RF connectors. I did not go into more detail,as your answer is not detailed enough. Thanks for asking and show a few hands of support.

You definitely have bad solder grounds. I have repaired a few of these. You will need a TV tech pull the boards out and resolder them. The worst board would be the one on the left [signal board, has rca jacks. rf connector]. And they may as well solder the second board. You will have a restored TV when completed. Thanks for asking and show a few hands of support!

There is no invertor board on a plasma tv. The fault is the X address buffer board. This is located on the bottom of the screen and runs horizontally the whole width of the screen. If you remove the heatsink plate that covers the x address boards and you need to look at the screen ribbon at the same position as where the bar is (in the middle).Vary gently lift the Xbuffer ribbon lock and gently take out the ribbon.Clean the contacts very carefully with a fibre pen or an electrical cleaning fluid.Insert ribbon back and heatsink and check.Here is a picture of the board and ribbon


a 1 inch bar is associates with 1 ribbon fault. So if the bar was 3 inches in from the left of the screen, the faulty ribbon will be 3 inches in from the right working from behind the TV. If cleaning dont cure the fault, then the Buffer IC will be blown and order a new centre buffer board (you can buy off Ebay)

Are you under warranty? Chances are real good that you need the signal board....the one with the rca jacks and rf connectors. This may be pricey $$$$$ but will surely repair the problem.

THERE MAY BE SOME CONDENCER LEKAGE SOMEWHERE IN THE HORIZONTAL SECTION

This is power supply issue, one or more of your filter capacitors either bursted and/Or over heats (this is why it becomes better when system cools down after turning it off for 1/2 hour..You have two choices.1. buy a replacement power supply may set you back a couple hundred dollars but it will be plug and play. 2nd you can replace these filter capacitors make sure the can handle 105 deg celsius not the 85 deg. celsius, if you know how to trace the bad ones and desolder and solder new ones on the power supply board, or hire a techinician to replace them for you. Good Luck...

I just had that problem. Check the terminal board that is on the left if you open the back of the TV. There is a thing in there with the number aa93-something. If you check under that board there should be some solders that have come loose. I just fixed this problem last night!!

Horizontal lines are either caused by the main logic board, a dammaged screen or by the main x and y drivers. Hard to determine which one it is, but somthing is getting hot which is causing the problem. My guess is the main logic board.

try lightly tapping the top of the tv where the bar begins. not on the glass but on top.

sounds like a loose cable inside the set, if not it looks like a logic main board
