I don't see that in the service manual. You should give some symptoms and details about the power on LED, fans PSU etc. You need to verify the PSU is good before you get to the logic board.

This sounds possibly like a power related issue. If you are using a simple power strip to plug into, consider replacing it with an Uninterruptible Power Supply (aka Battery Backup, UPS). AC power related issues can cause screen waviness or shaking. Be sure to obtain the proper capacity unit for your needs. These units are rated in Volt AMPS and come in sizes from 300VA to 1500VA in the consumer product line. APC, Belkin, Triplite, CyberPower are some popular brands. The VA capacity to choose should be considered over price alone. Buying the cheapest one vs the right capacity can result in not having a unit capable of protecting your devices plugged into it. Understand these have 2 primary functions, 1. surge-protection 2. battery backup during a power related problemThere are 2 different banks of receptacles on these units. 1. Some for surge protection AND battery backup2. Some for surge protection ONLYYour computer would be plugged into the surge AND battery backup receptacles. When a power related incident occurs, the unit quickly switches the devices plugged into these receptacles off of AC power to the batteries, until the power issue is resolved. The time on battery is limited based on the VA capacity mentioned earlier in this solution. So buying the largest VA capacity unit you can afford will simply give you more available time on battery before the batteries are exhausted and must be recharged. On the other hand buying the smallest VA unit could result in an immediate and unexpected shut down of the computer if a power related issue occurs and the battery backup cannot handle the devices plugged into it. NEVER use these units for battery backup of Laser Printers or other high curent devices. These can destroy the battery backup.I hope this helps with your screen issue.
