Re: analog pwr board smoking

On this model there were two power boards used, i would look at the srp# on the power board and see if it is the same as the replacement. If you put the wrong one in it can burn up, but usually there is no damage to the rest of the set, just put the correct board in and power up. Hope this helped.

Set worked fine when turned off. Now nothing happens when pwr button is pressed. Timer light does not come on. If system reset button is pressed, pwr led flashes for 60 secs. System is still dead. Status...

If your tv is around 2-4 yrs or used 6000-8000 hrs,never replaced the lamp before it could be time to replace it.If you hear strange noises like buzzing or humming noises it could be the color wheel which is a little disc that has a gamma of colors and spins at high rpms.When the light of the lamp goes through it creates the colors on your tv.The other most common failure is the board that powers the lamp,which is called the ballast.When its bad it will make a clicking sound or like wanting to turn on. For parts you can find them in or God bless.

Check if this happens in analog inputs ( connect a DVD player or any other component uing RCA cables white,yellow,red ) then check if the bars are showing on digital unputs ( connect using HDMI cable )

if it is just an analog problem - replace analog board
if it is just a digital problem - replace digital board
if it is a problem with both -replace DMD board

A chip on the circuit board started smoking

The component sounds like a resistor, and the fact that it was attached to a heat sink means its a power handling resistor. You said it was burning, so this means that whatever it is attached to is drawing too much current. From what you are saying a component on a board is drawing too much current and is causing another component (the 1 ohm resistor) to burn. My question is what board is this (I am suspecting the deflection or the HV power supply). Please post a picture of the board in question. That way I have a visual guide as to the board and if I can find the schematic, or if you can supply the schematic I'll be able to at least give a better diagnosis of this problem.

Thank you,

Good Day, Butchilee,
Sounds like you have patience, hope your TV has some trace left. Hit recommends that you replace the originals with
STK-392-150's and the resistors. Replace said items with care then back down on the screen/ focus controls and gradually bring the screens up until you have pic, adjust focus. Go into customer menu and adjust color down, set brightness to 50%, contrast to 100%. Then go back and adjust the screens for proper, black/white, tracking. AND It's best to double check the soldering connections.
Good Luck, Big Irish.

Green Plaid then Vertical Lines, Failure of hard controls, Analog Board?

You are absolutely correct, When anyone complains of vertical lines or bars, the next step is to see if it happens on only digital inputs ( digital board ) , only analog inputs ( analog board ) , or both ( DMD board ) .

Analog board can be purchased at ,
