how many blinks does the red light give in a row? This would be an error code?
The problem for 7 blinks would be an Interface board. Apparently there is a glitch in the interface board that sends signals to the television.
Basically the glitch shorts out the board and the t.v wont turn on and
you will see the power light blink 7 times pause then 7 more. You can
replace the board with a new one and update the software on the new interface board.
If is isn't 7, let me know and I will help you out with this
First thing to do is reset ( see link below) and see if it resets otherwise if problem continues it will need some work
Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. There are some common breakdowns in the High Voltage circuits in this set. One is the flyback transformer. Another is a small high voltage capacitor in the sweep corrction circuit. There is a cap that goes open in a high voltage circuit (C6532) which needs to be replaced. Support bulliten by sony Thread on your model
The blinking seven times is a fault code to locate which area of the TV has developed a problem, this is a protection mode to prevent further damage. I would need to know what model of TV you have to try & give you an idea of which section of the TV is at fault. This could be a power start up or scanning fault.
Hi, Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number... A1085447A* LAMP BLOCK ASSY XL-2200U It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.
Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.
7 blink error is 8.6 volt error on that model. usually tied to y sustain board located on left side of set looking from back. disconnect y main from power supply and power on and if comes on verify power supply primary voltages located on label on pdp itself. if voltages present you would need to replace that board as not designed for component level repair. however if you find failed components like swollen caps or burnt ic's you could replace those. also when replacing the y main board there are two y buffer boards to left of main board that also would be recommended to be replaced at same time as they work as circuit and replacing one board without other could cause failure to other boards still in set
You have a 8.6v supply error according to the 7 error code being displayed, what you can try is when the set goes to blinking disconnect the Y sustain board (if looking at the tv from the back the board on the left) from the upper left side of the power supply, if the error code stops then you know your Y sustain board is pulling down your power supply and causing the error, if the error code continues you have a probelm with your Logic Board (located under your Small Signal Board) disconnect this from the Y sustain board and see if the error code stops if it does you know that the Logic board is bad, if the error code is still blinking then the 8.6v supply line from the Power supply is faulty and the Power Supply needs to be replaced
