I need a manual for a flat screen Protron TV?
SOURCE: Protron flat screen tv
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
make sure the remote works first!
one way to check it out is using your cellphone camera and point the remote to the camera and see on the camera for any light that come from the remote.
make sure you have good batteries
