Your printer is a cartridge printer and the print heads are installed there. Cleaning them won't do any good because they have a chip, if you want to clean them you can use an ultrasonic bed.

Where did you connect the fan? If you put thermal paste on the processor, one theory is that it starts up like crazy because it detects overheating.

You must reconfigure it again: Insert the product CD into the CD/DVD drive or download and run the product software package: WF-2650: epson.com/support/wf2650 (U.S.) epson.ca/support/wf2650 (Canada) WF-2660: epson.com/support/wf2660 (US) epson.ca/support/wf2660 (Canada) Follow the instructions on the computer screen to run the setup program. When you see the Select Your Connection screen, select one of the following options. options: - Wireless connection Have your network name (SSID) and password ready. - Direct USB connection Make sure you have a USB cable handy (not included). - Wired network connection (WF-2660) Make sure to have an Ethernet cable handy (not included).

Possibly the screen flex is not making proper contact, press lightly on the bottom of the screen on the protective plastic and see if that stripe in the middle is removed.

Did you try another cable? Check if the charging port is dirty, a drop of WD-40 and a needle can clean it. The charging pin may be damaged and may need to be replaced.

Any new disk that you buy, you have to initialize it, use a pendrive with ubuntu and format it from there so that it recognizes the machine, it has worked for me many times. Good luck and greetings.

Buenas noches, los puedes encontrar facilmente en EBAY.

En una Macbook, tienes que formatear el disco nuevo necesitas tener presionado Comando + R, para que te salga los discos y particiones que tengas, si no te aparece necesitas el USB o disco de instalacion para que lo puedas ejecutar. Saludos

Hola. Tienes que desarmar todo la computadora, sacar la motherboard e ir cortando los contactos plasticos que sujetan el teclado con el cover, es sumamente sencillo. Saludos
