ESA/Akai PDP4294LV1 plasma
in beautiful condition powers on and has sound but no picture
i opened up back and found a blown 250v 4amp 5x20 fuse ..it was located on a board to the rigfht back of the tv and had one harness coming from the power supply to that board...not sure what the board is for...i repalced the fuse and still no picture and the fuse does not blow....very weird...
any ideas??? all the caps on all the boards look fine......i checked all other fuses on all the boards and all were good
tv power on fine no blinking lights....just no picture..
if anyone has any ideas please email me at dcxguy48080@yahoo.com
i also need a service manual
thank you
Get the MODEL number from the pdp (display panel), and the number from the board with the blown fuse (probably ysus or zsus sustain) and search for repair info on that panel/board. Possibly a bad STK module (under the big heat sink) on ysus, could be many other things.

yes well the blown fuse was located right next to the power calbe coming on the Z-sustainer baord
and like i said when i repalced the fuse the fuse did not blow but the tv does the same exact thing...no pic or onscreen menu ..just sound and everyhting seems to function when i click the input button it seems to cycle throug as does volume etc...
i then just unhooked the power cable to z-sustainer baord and the tv did the same thing..powers on fine but no pic ..just sound....to me it seems that the power to the z-board or the z-board is just dead.......is that possible?? and also soeone said it could be bad stk on the z-board is that possible ....to me if theyr were bad then the fuse would blow everytime but im not an expert so......
i appracite any help you give me...i really want to fix this tv....i can get a z-board for about 125.00 but i want to make sure what the source of the problem is first......and by the way i get no flashing error lights...the tv has a solid green light when powered on....and stays that way.....with sound...i hooked a dvd player up to it and it sounds fine..jkust no pic at all
thanks
I have an esa/akai pdp429lv1 as well. Sound but no picture. Seems a common problem for this TV.

Plasmas are only made by 3 companies essentially even though you see many name brands. Typically your set is an LG, Samsung, or Panasonic inside. The power supply and signal reciever, tuner and av inputs might be made by akai, or zenith or someone. But the guts of your plasma are only those 3 makers.
But if you get absolutely no picture...as if the set is not on. but you get sound. That is usually the z-sustain board. Don't go based upon your model if you look for it on ebay or other sites open your set in the back (leave it unplugged overnight before) and check the exact part number for your z-sustain.
Before you go buying boards look at your power supply. Had the same problem with my LG Plasma and after looking over everything I had 8 capacitors that were bulged or leaking on the power supply board. I replaced them with ones I bought from Digi-Key and my TV works like brand new. It cost me about $12 in parts shipped (I ordered extras).
hello i have questions for esa plasma tv - model PDP4294LV1. i have a red, sort of psychedelic-looking snowy picture. I can hear the sound just fine but no picture... can u help? have had unit about 4 years & would prefer fixing the tv if possible. thank you
A/V Main Unit Board is bad is what I was told by a Tech, chip under heat shield.
I have an ESA model PSP4294LV tv
For a while now the screen would just go black with sound then in a few minutes or after turning it on and off it would come back on normally
Recently it has gone multicolored with sound and then will shut off blinking a green light
I unplugged it, waited and then turned it back on to have it do the exact same thing
Ours was one of the first plasmas and about 10 years old
We were told it had limited hours of tv time in its life
Is this the end or should I try to fix it?
Thanks for any help or advise
