The image is suffering from solarization. I'm suspecting the AS19-H1G chip.

can you post a picture of the fault a bad main board can cause solarization too sometimes.
on the tcon there some gamma test points can you test them and post the voltages usually 1 to 22 test points

I will not be surprised if it has bad GAMMA Voltages.

Philips T.Con Part Number 996510018929. Gamma IC fault is very common with this board. if you are looking to replace board match the bar code number 35-D024023 any other board will not work correctly. If you are thinking to replace the IC, preheat back of board before applying heat to the IC makes life easier

Hello Flocko & Budm,
Thanks for your advice which is appreciated. Hopefully someone can shed some light on the readings I've just taken to confirm if it is a bad Tcon board. I have included the picture being sent from my laptop for reference.
Regards

yes defently bad so you either need to change the chip yourself (or find someone willing to do it for you if you havnt got the tools/skills ) or look for another tcon that there willing to accept returns on if faulty.

Hello vinceroger69
Many thanks for your diagnoses. I may try and change the AS19-H1G chip myself having had a steep learning curve on a previous Tcon recently not realising that the chip base was soldered to the board. Won't fall for that one again. Thanks to everyone for their help and assistance.

Too be honest ive never tried to change one so wouldnt know, although i have read various post and peoples opinions of how too change them.

Go for it ,You will never know until you try, the worst that could happen is you will damage the T.Con board, and it faulty anyway. So just take your time, good luck let us know how it goes

Hi all,
The set is now up and running after a friend replaced the AF19-H1G IC for me and he did a neat job.
Thanks to all for your help and advice.
