Hi check your PSU secondary voltages on startup then check them again when the screen comes right
could be caps failing

Hi Chrissie: Go with Sabre's suggestion, check the voltages & check the Electrolytics on the secondary side of the psu with an ESR meter.
Or to narrow it down use the old Hairdryer / Freezer trick.

Chassis model Vestel 17MB12-3
Check SMD Q-862 on PSU (BC-848) temperature sensitive
