Hello
There are two possibilites for this fault. The first one is shorted inverter transformer in the backlight inverter board. The second one is the fault with main board. For both faults, card base replacement is only possible. Check out which board has the short, and replace it.Image of the digital board is given here. Baclight inverter board can be located aty the panel itself, will be fitted vertically at the right or left side of it.i have a 26lb30h proscan 26 - 2_8_2012_5_34_32_pm.jpg

SOURCE: proscan lcd tv model 26lb30h blows fuse on power board

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.

Bought a 26 inch proscan from Costco on line. Tv won't turn on, led light is off as well. own TV approx 2 years wah can i do besides leave TV curbside?


Hi sglassgold,

Here are steps that may help you fixing the problem. You should prepare tools and multimeter.

I'm assuming that your unit is dead set and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I've advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact on the board, don't attempt to touch anything because there somefatal components stored electricity enough to hurt you with a simple mistake only.

The next steps should be done by an expert or qualified technician because isolating the problem on the power supply is technical and complicated. I would advice also to replace the entire power supply for your convenience if finding technician there is not possible.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.



Hope I helped you.



Have a nice day!



Thanks for using Fixya.

The power cord easily falls out on my model, try twisting the power cord where it plugs into the TV until the red light comes on in the front.
