This is how I approach this problem: I check for menu appearing on the screen: If it has menu, I look at connections. If it does not have menu then I check voltages from the power supply. I check for the following voltages. VSCAN, VS, VE, VSET and VA. If only one voltage is there, then, the PCB that needs to be replaced is normally the SMPS and/or the Logic. If all the voltages are there, the Digital PCB should be replaced. If it is missing one voltage, I disconnect the Y Main and X Main from the power supply and check if the voltage reappears. This symptom is normally caused by one of these two boards having a short on the missing voltage line. The defective PCB and/or the Power Supply (SMPS) need to be replaced. If you are in need of a technician, contact Samsung at: 1-800-SAMSUNG If you have any other questions, reply to this post and I will respond.

Dear Jimmy, I have a 50PA4500-UM from LG. It has sound but black screen.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

My Samsung SP-P4231 has sound but no image. How can I fix this?

Go to eBay and search for BN96-01217A.

That is the power board used in SP-P4231 and the most common reason for the problem you have.

(not guaranteed, just statistically most likely one; if you care to check measure the Vs voltage at the power output - shoudld be about 87V and will probably be much less, say 30V)

Hope this helps!

Samsung HC-P4741W has no picture and no sound

Doubt it is the convergence board. It is in shutdown mode caused by an overcurrent or overvoltage condition. It will take some troubleshooting to pinpoint the part(s) that are defective. Could also be a cracked solder joint.

My samsung TV won't show any picture/sound.

When the TV is on, need to check the back light is on(go back side & look into through)

If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)
