Goodee Projector blue LED on but power button do nothing
If it doesn't have replacement main board it may be somewhat difficult to repair unless a service manual is available and most the time they aren't. I'd lean towards a defective voltage regulator as the short most likely killed the 5 volt supply
Vizio E65U-D3 purple / blue tint on the entire screen.
A main board would never cause the entire screen to have a blue haze as long as you have video and I assume you do. This is a common issue of backlights being over driven and the temperature K value goes up from a cold white to blue purple color. If you order and replace the backlights it will have the right colors again. You can remove the screen and defuse sheets to get at the LED strips, power the set up without the panel and screens in you will see the lamps are blue colored. Best place to get new strips is shopjimmy.com. Fast shipping and the best customer service

CP150 Capacitor Replacement
The swollen electrolytic cap dose indicate defect but, also may mean a run-away voltage from an open zener diode or shorted regulator which regulates voltage. With luck, replacing the cap may do it, but may not complete the needed remedy. If you are not proficient with soldering or PC board work, I would strongly suggest taking unit to qualified service for complete analysis and repair
RCA 52" Menu Keeps Popping Up and Down
I see this a lot at the shop. the front panel buttons have become damaged. The best coarse of action is to replace the front button circuit board assembly... **** there is a temporary fix until you get the part... remove the front panel and take button circuit board out...just use remote to control the tv. This is also a way to test to see if this is the problem.. if you remove the connector to the buttons and the problem goes away then the buttons are the problem. you get get this circuit board at union electronics. You have to get the extended model number off the back usually d52w20yx1 or yx2 or yx something...not to difficult a repair
