Bush LCD27TV006 / Maxim and models with similar power supplies. I have found the following problems!
(1) PSU blown up! stby i.c. FSD200 s/c + 320v print to it burnt out.CH & Son do a kit which i have used and this work very well.It includes i.cs and all items needed,but it is listed under Maxim 11-54. The kit no, is Mod kit 63.
Also i change the following D326(1N4005)/stby opto i.c.

63V 105C used.
(2) FET T300 S/C Dry joint pin 1 chopper tx TR30 (So much for lead free solder!!)
(3) Stby LED flashes & pulses (tv wont start),Check 1000mfd cap is not bulging,i think its on the 5V sw line.Sorry have not got circuit. Note new cap gets hot, in fact every one of these PSUs faulty or new get very hot
