Sharp aquos went out and I have no picture just sound


The board that controls the picture is in the middle of the screen when you remove the back of the TV. It has 2 flat ribbon connectors going down to the bottom of the screen. Make sure all the voltages on the power supply board are present, then take off the metal cover to expose the board. Look for obvious burnt parts. Sniff the board to see if there is a burnt smell. If there is then go to
TV Parts Universal TV Stands DLP Chips ShopJimmy to get the replacement board.

its better if you replace the whole power supply board rather than replace the burnt surface mount parts because commonly if the surface mount parts burnt out there are some shorted parts that cause that burnt and possibly repeat the problem..

Please rate..

Philips tv smokes


Do this only if you are a qualified service technician:

This problem can come if any moisture has entered or is formed inside the TV.

Switch of the power outlet, and remove the plug. Open the back cover and check what are the parts burnt visibly. If it is in the SMPS area, you may require a thorough check on the load and replace all the burnt parts by looking through a Service Manual. Anyhow, this might require attention by a qualified service technician.

When power on u can see the screen for 4 seconds then it turns black .. Can anyone help me!!!...PLZ...???


This can be due to a protect on the board as it trips due to a short or malfunction within the main board.
Also it is important that the voltages be measured +B to the circuit secondary side.
Finally check for heating components or burnt component which can lead to the suspected part. A faulty IC within the processing drive circuit cannot be ruled out. So a need for a schematic check up.

Dead set. Smoke came over the TV.


The smoke is usually came from burnt resistor cause of short circuit or shorted parts inside..

Try to open the back cover of your TV and look at the resistor burnt..and replace it..also try to find shorted parts connected to burnt resistor or behind it..

My television shuts back off when i turn it on.


It may thing there is short circuits, so the power supply shuts down to protect itself from further damages. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
