Looking For Advice on Testing TX36PF10 CRT Tube

[Mike-s]

Hi Looking for some advice have a Panasonic TX36PF10 CRT television
When switched on no picture the background gets brighter and brighter then the left and right sides of picture move in towards the centre and television shuts down although audio is fine total time about 5 seconds and power led on television flashes 2 pulses every couple of seconds

Does not switch on by remote afterwards but can be switched off then on via main power switch and will follow the same procedure each time

Have included picture of screen Looking to see if it’s the CRT and a waste of time and money or a cheap repair

Have electronics experience although not on TVs my background C&G 224 control systems and HNC electronics have most test equipment except a high voltage probe looking for a service manual or some test points and expected voltages waveforms to confirm if it’s the tube

Would appreciate advice or comments

Regards Mike
