How to remove glue holding down capacitors?
Powering on issues from cold is a capacitor ESR symptom. As the capacitors warm ESR is lowered, so a marginal capacitor can become operational when the TV is warm. If marginal, warming the caps gently with a hot air gun/hair dryer aimed at the caps can prove it, the fault will appear to go away if so and allow you to power cycle.
