Not in any service bulletins I have seen, nor on the internet.
What is common is that the laptop may have been dropped, or an object left inside when the laptop was being closed, or eventually the hinges just wear out.
A loose, or defective hinge will put a strain on connections from the laptop, to the Display Assembly.
Damage, or a loose connection, can occur with the Video Cable.
(Video Cable from motherboard to Display Assembly, and cable to Inverter)

Left-click on Display in the list.
Scroll down to the third photo.
Under - 8. Lift the display out of the cover
No.3 - Display cable pull tab - shows the video cable (Display Cable) connection to the motherboard.
See if this connection is tight.
The Display Cable is an FFC.
Flat Flex Cable.
It has NO connector on the end. It is a flat cable composed of individual wires, laid flat next to each other.
Each wire is insulated from the other wires.
The end of the FFC has bare contact pins for each wire.
The connector on the motherboard is a ZIF connector.
Zero Insertion Force.
The FFC is slid into the ZIF connector, in the PROPER alignment, so that the contact pins in the cable, line up with the contacts in the connector.
(OBSERVE which direction the FFC was installed before removing it. Some are installed twisted over one time. It MUST go back the same direction it was originally)
The ZIF connector has a blue Lock Tab.
This lock tab is brought straight up at a 90 degree angle, to unlock the connector, and free the Flat Flex Cable.
In the photo I pointed out above, the blue Lock Tab is in a vertical position. The position for removing the Flat Flex Cable.
Not a loose connection at the motherboard?
Check for obvious signs of damage to the sheath of the Display Cable.
The sheath could have been stretched, which in turn can stretch the wires, and possibly break them, or cause an intermittent connection.
No obvious signs of damage?
Next check the connection on the back of the LCD screen.
Not loose?
Remove the Display Cable.
Use a multimeter, and check each wire for continuity. (Ohms check)
Have a helper gently wiggle the cable, and see if there is an intermittent reading on the multimeter.
(Break in wire/s)
Check connections for tightness to the Inverter.
Report your findings back in a Comment.

This is a common fault as the set on ageing deteriorates in the connections. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.
The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.
Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.
Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.
This is can be due to poor connections in case the set works on some occasions. If not the main board is a suspect.
