I have a Polaroid 323b I have power on half of board no stand by power.can some one help,
The R0804-0901 is extremely simple in regards to operation and outputs. Unlike most TV power supplies its only standby circuit produces 24V and those can be measured at any time - on or off - at connector CN3, where the first three pins are ground, the second three are +24V and the last one is used to turn on the secondary power source for the back lights:I check and no power for standby.Where power plug's in there is a small round black (250V 15A ) is this a fuse ? T5 0Al/250V

You can check that the power supply is getting power from the power cord. then check the fuse on your power cord. Last you can check the output power of your power supply. You can get parts from www.interliquidparts.com

Samsung un40es6100f with no sound video or backlight. Would you agree this would be a main board issue?


Do you have a standby indicator in the front of the TV?..if you don't check the standby voltage, if its missing replace the power board, if you do test the PSON and see if its ok, if it is then its the power board if its not then the main. The PSON or it could be PWR-on as is the signal coming from the main board telling it to enable PFC and go to work basically, without that the set is dead but if you see that voltage then its a power board issue as the main is telling the set to come on

LG SMART TV 55 INCH 55LN5700 Which board to relpace


Sounds like the main board is going out. It tells everything when to do something and what to do. It even tells the power board to send power to the backlights.

Lg 47lw5700 not powering on, red standby light blinks. Removed back panel and tested power supply board.


3.3 is the right reading on the power switch on pin...so the main is telling the power board to turn on like it should be, your power board is bad.

I have a Vizio E50-C1 Model #LTCWSKAR Power supply # (X)ADTVE2420AD4 Main Board #GXFCB02K009050X


You need to find out which board the led driver resides on. The main board sends a signal to the power supply board to turn on the LED's Look on the power supply board for swollen capacitors. They all have to have flat tops. If any are bulged, they have to be replaced www.shopjimmy.com. TV Parts Universal TV Stands DLP Chips ShopJimmy These guys can tell you which board you need.

Phillips 39" tv problem


a power surge can do alot of damage but does your model have a fused plug? as would check this. if you have changed the power board for a know working one then the main av board has gone this is the board that tells the power board to turn on.

I will tell you that there are many screws involved in getting to the boards. Suggestion I will tell you about

Keep the screws separate. Take the legs off first, then the back panel. this will expose the boards. The board on the top is the power board, below that is the main board. on the 32" vizio there is one plug that is located "left off center" that is very easy to break when removing from the board. Just beecarefully

Power light flashing once


Ouch...ok a one blink code could be either the P (power board) or the SC (scan board)...only a service tech call can tell you for sure. Ask around for some quotes first.
