I want to fix my Power supply television. After I compare all the component with a new board used special tools, they have different value. I want to order in DigiKey. But which one component I choose. Can somebody help me?
All the blue color capacitor want to change.

Your larger round component is an MOV. Kindly see the below option from Bourns:
MOV-14D751K Bourns Inc. | Circuit Protection | DigiKey
For the smaller round component here’s an X1Y1 Ceramic Disc Capacitor:
DE1B3RA471KJ4BH01F Murata Electronics | Capacitors | DigiKey
For the square block film capacitors, what is the measurement of the spacing between the legs on those?
Are you sure @Kristof_2649 MOV-14D751K is It 750V?. Cause it is power supply for TV. How about picture number 1?. If I search on website. It doesn’t have a data sheet.
@Kristof_2649 is definitely correct about the MOV. The marking on the part is quite clear. Note that the 750V rating is a typical varistor rating, not the operating voltage of the device.
The last items. How about this @David_1528 or @Kristof_2649 ?

Hi Axeda_Studio,
To pick out an appropriate match, you will need to measure your caps and then look at the parts in the links I provide below for ones with the same lead spacing (pitch “P” in diagram below) and, if you have other space constraints, the width, height, and thickness.
The left capacitor in your image is a 1uF 10% tolerance 450Vdc Metallized Polypropylene film capacitor. Here’s a link to caps that meet those electrical specs. Note that higher voltages are just fine and would just add a level of durability over lower voltages.
The right capacitor is a film type 0.47uF 10% 275Vac X2 type safety capacitor. Here’s a link to caps that meet those specifications. Again, look for parts with the same lead spacing and then other dimensions if you have space constraints.
