IC4011 INDICATED CIRCUIT FAILURE

I need more help with this problem. Does anyone have model specific experience that can guide me to this transistor and cap? Are there any other parts I should change? If I had a list of cheep parts I could order and change all of them. There is no noticable damage to the board. posted by Rhino-AE on Feb 08, 2008 Report abuse

No Video or Sound. Power Light Blinks 5 times = IC4011. Where do I go from here?

This trans sister and cap is going to be close to the hot which is high voltage be careful !!!!! the hot is a big red some times black with red thick wires, the transistor will have a silver(or black) heat sink with this larger transistor attached to it. the cap is going to be right by it

Powers on blue screen,no picture,some red lines virtical yellow back round,where is the reset button ?model WD62526 HDMI.


You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections.

The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad.

This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced.

The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

Vertical amp chip needs re soldering.--- very common !
Vertical amp chip has failed and needs replacing !
Failure of electrolytic capacitors in vertical circuit
Failure of resisters that supply volts to the vertical circuit
Failure of deflection yoke ( not very common )


Also it might be a convergence board failure. Changing one board will not necessarily fix it. It is recommended to change all 3 boards in the unit. many try this as a DIY and fall afoul because it is a specialist job to retune and reset the parameters. The cost then becomes greater than if a tech did it correctly the first time. Be advised it is not a simple DIY.It requires soldering and desoldering skills, specialized tools and a knowledge of circuit diagrams.

Was watching tv and just went completely quiet no sound at all? dont even know where to start looking......just had to put new lamp in it not even a week ago.......what is wrong with it?


Sorry to say the AC cord is causing the problem. Heat is the enemy of electronics, and these sets operate hot. You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on with sound and continue to operate component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. I suspect a problem with the audio circuit. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment.

52 inch panasonic projection tv won turn on and flashes what appears to be a diagnostic code?


The most common error codes are when the set does not turn on the power light on the front blinks in a sequence---most common is 3 blinks, a pause and 3 blinks etc

If you have to, unplug the set and try to turn it on again and see what the sequence of blinks is.

Let me know what you find and I will try to tell you what it means.

Horizontal output transistor failure


check b+ comming from p/s. also check for blue flat caps in line with h-output circuit. if blown out the side. remove them from circuit. also might have a HVT goin bad. I believe this is also the model that might have a mod for h-out running too hott that requires adding a resister in the h-drive circuit. also try a heavier duty h-output.

Repairing Circuit Board


Q553 is a mosfet transistor NTE2973 ,caps1200pf 2k volts c552 is probly good, you might also have to replace STK-392-110s if so you will have to do complete convergence alinement. you need someone who knows how to solder,and do set up alinement for this does have to be done by someone who knows how if not done correctly you can shut set down,then you will really have trouble!!!!!!

Won't turn on


The 5 flashes of the light on this set means there is a problem in IC4011 or the surrounding circuit. Not a job or the inexperienced. Call out a pro to assist you in this repair. Good Luck
