Panasonic Viera Tx-32lmd70a intermittent fault

[sordids999]

hello guys

promised my auntie ill try and look at her tv for her so i finally got round to looking at the tv
i know its a old style but its immaculate it can take a few times to work by switching it on and off via the power button,but after 4-5 attempts the tv works
if i try with the remote i just get roughly 14-15 green blinks then goes back to red standby but still does not work

any thoughts

thanks

Update:
I can't seem to get the fault showing up it seems to be when the tv is left off for a long period of time

My guess would be caps - small start up cap/s?
When it is cold warm them up with a hairdryer and see if it fires up straight away

Could be soldering failure on the processor.

strangely enough she told me today it started just before her warranty run out so she just carried on pressing the switch to get it working

Could be on/off switch failure - set is prob 6 years old so given 3 yr extended it has been
pressed a lot?

@selldoor
just before the end of 12 months it played up she said ill wait until its cold then try the hairdryer test
@tom

Yes...
Worth checking if the power supply outputs are OK during the fault.
