Panasonic Q

Ive had my panasonic Q for over a year now, it was fully modded and has played pal dvds fine for all that time. Yesterday i turn it on and got jap menus, this was quickly changed back to english but now it wont play any home made dvd's/vcd's pal region 2 dvd's or pal region 0 dvd's. It says the wrong type of disc is inserted, please insert another disc.

Ive got a feeling the pal mod has gone wrong somewhere, as it doesnt display pcb when it would play vcd's, just says 'no play'.

Anyone know how to fix this or get this fixed cheaply? Its very hard to find any info at all about panasonic q mods on the net.

Thanks :)
