Protron PLTV 4250- wont turn on-
Had the same problem with one here- The 110v end of the power supply board was found damaged, The following items may need to be replaced:
Fuse F1 (soldered in) . 6.5a @250v time delay
Mouser 576- 021506.3HXP – note this style is for a fuse holder instead of solder in- I added a fuse holder on the board
RT4 & RT5 inrush surge suppressors - I used shintron 8d-18 power suppressing thermistors
BD1 bridge rectifier - Mouser 627-D15 XB 60H Shindengen
If you want a little more protection modify the board as follows:
1.replace only RT5 in its original location & move RT4 into the other ac input line in front of the bridge rectifier. (cut trace & drill solder holes)
2. Add: MOV (metal oxide varistor) across ac inputs of bridge rectifier.

This arrangment is copied from a samsung power supply.
Be careful when plugging in the I/O box on the outside cover, if any pins are inadvertantly bend loss of picture will result.
I have pics if anyone needs them .
