Philips 42PF5521D/10 Screen

[dick_barton]

Hello,
Currently the on/off led displays - 1 slow green flash, 2 fast green flashes which I believe reading through the forum is a PSU fault and is generally down to SMD capacitor C2508 requiring replacement.

However the the screen has got a noticeable scratch and my request for help is :-
Has anyone successfully polished out or minimised scratches on the screen and if so I would very much like to know your method(s)
Regards

C2508 replaced and the set now up and running.
Still interested to know if anyone has a successful method of reducing the appearance of a deep scratch.
Thanks

Plasma front protection-glass (Have to stop myself calling 'em implosion-glass) are usually coated both sides with a thick plastic film.

On an old 50" LG some time ago, I removed the outer film from the glass itself, but this does cause certain safety issues should the glass be broken.....

As to the issue with your set, it can be lessened by the use of Brasso and then after cleaning well, a mix of oil and wax carefully applied and polished out will minimise it further.

Awesome How ever I really do urge you to replace the primary transistors on that Psu and all the Smd lytic caps. Seen the transistors explode and was a nightmare to flipping repair the board.

Alastair , does this also apply for the 2010/2011 Panasonic models? I got a Panasonic where the coating has been damaged. How did you remove the coating?

Possibly newer Pdps (2010-2014) the screen on the front is actually the PDP glass with a layer over it. What Tv is yours ?

Hmm , think so to. Its a sort of coating.

I use a 42PZ80EA for testing purposes. Bought it for repair but after repair the glass hit the backside of another tv. ( cooling block from power supply ). And it left some cuts in the coating.

PZ80 have a separate front glass which you can remove I have also had to clean the 42" glass Think they didnt add enough foam to seal the edges which lets dust fall in.

The cuts were to deep to successfully remove. Tried brasso, vaseline, even used uPVC cleaner which is very mildly abrasive.
These may work on minor scratches but didn't work for me.
