Smoking y buffer board

I think that the TV set is giving you the message that it is junk and will cost more to repair than replace
Smoke is a pretty good indicator that more than one component and board will be rubbish

It is possible that the buffer board will fix your problem, but try removing, cleaning and reseating the flex cables between the buffers and the panel first. All it takes is a little bit of dirt or oxidation to open a connection and cause a line-out condition. Use a lint free cloth and a little bit of alcohol to clean them. Make sure to fully insert the cables and center them perfectly in the connectors or you will have even more lines. If the original line is still there after cleaning, then try replacing the board. Buy a board from a reputable dealer that will guarantee no problems with the board. If you still have the line even after changing the board, then the plasma panel has failed and the only fix is to replace the panel.
Always let the tv set for an hour unplugged before attempting any repair work. There are dangerously high voltages in plasma tvs that can cause severe shocks or even *****.

Looks like you need a new board.

here's the link to the replacement power board.

Ur tv have 2 long buffer boards that help the Plasma screen panel to have a backlight to produce a picture.Those 2 long buffer boards either one it is dead or both 2 long buffer boards are dead.Those 2 long buffer boards it is the causes.U must have some mechanical skills and some basic electronic skills,like to take out those 2 long buffer boards out and have test and replaces those ethier long buffer boards it is dead or both 2 long buffer boards.If u have no mechanical skills and electronic skills.Best just call and take estamate of many prices of those tvs shop in ur cities area for the best prices and pick one tv shop and get ur tv repair.

Hello, I hate when this happens to my tools. This could be a number of issues. I would think that the transistor that controls the motor speed is shot or the motor itself is loading the transistor causing the smoke, or the brushes internally of the motor are worn and causing the overheating, hence smoke. Is the unit new or well used?

1. Check for bad capacitors and transistors both through mount and
surface mounted in the vertical section of your TV.
2. If no problems are found focus your attention on the tuner check
for broken connections wiggle your coax connection to see if the
problem clears also check for open inductor coils.
3 Check the vertical and horizontal output chip if they read shorted
replace

U have a dead power supply board,burn componnents parts on the power supply board.Replaced the power supply board,u will get ur power back as normal function as before.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

NEED REPLACED MAIN Y ASSY AND Y BUFFER UPPER ASSY AND Y LOWER BUFFER ASSY

Time for anew one.

It sounds like the power supply transistors have failed. You'll need to pull the clamps and get the numbers off of the transistors. It's also possible that the 47 ohm gate resistors have failed. After removing the old transistors, you need to check the resistors individually.

Since you're new to repair work, read the following page.

Basic Repair Introduction

Post the part numbers if they are incomplete and you can't find the correct replacements. mouser.com is probably the best place to buy small quantities if you're in the US.

You also need to check the output transistors to see if any are shorted. If they are, the repair will be more difficult (especially if there is damage to the driver board).
