Transistor C5707 Equivalent Part Number

By on August 25, 2008


I got lots of emails asked about the substitution part number for C5707 transistor that were used in many LCD Monitors. I normally asked them to buy online as original part number is still the best part for replacement as it is not easy to get a replacement for this transistor. For your information if you have the C5706 transistors you can replace it with C5707 and i have tested it and the LCD Monitor worked perfectly okay. To some that can’t order the parts online and can’t get it from local electronic suppliers, in fact you can try this part number as replacement.

Try use TIP3055 transistor as recently i came across a website that says that it can be use for replacement for C5707. The TIP3055 is bigger in size compare to C5707 but with some adjustment you could easily fit into the board. However i haven’t try it before because i could get the C5707 from the local market. Try it and please let me know about the result. By the way you can download the C5707 transistor data or specification from this website-please click HERE.

    Hi Jestine, While building some small projects I sometime can't find the exact transistor to use so I need a replacement, do you know a website I can use which I can type the trans No. and I could get an equivalent for it.

    TIP3055 transistor must be installed on the contrary with c5706/c5707 one. And it doesn't work properly ( tested on VE710b ) - display starts but 2 seconds later the backlight is go by dick off. so then reflow 2 5707 transistors - working fine about 2 16 minutes.
    Thank you for your attention! Best regards from Russia!

      HI Voyager,

      Check to see if the tuning cap have problem or not. it is located nearby the high voltage transformer.

        Is the Tuning cap the 450V 100uF, located near the AC input transformer?

    Hello Justine, C5707 can be replaced with C4242 (2SC4242) because i have tested many transistors but only with this one lcd monitor worked okay.Best regards.

    • Jestine Yong

      June 23, 2012 at 9:56 pm

      HI Darkmen,

      Thanks for the good info. My side here I will use back the original number since I could easily get them. If the readers can't get this number they can always try the number you have suggested.

      HI Adm,

      It can be bulged e-caps, dry joints in the transformer, one of the high voltage transformer have problem and one of the backlight weak.
