Tcl #l32b2500

[SEAWOLF]

I am servicing a TCL L32B2500 with no screen light.When I press the remote
to switch on the television there is a dim flash of light on the screen and there is no picture. When I look to the back of the tv there is no led light.I do not have a service manual for this tv but the voltage on the cable which goes to the
LED backlights is 45v and I do not know if this is correct.

Is this your schematic Your photo's are to out of focus to be able to compare your board with the schematic.

Looks like you have bad backlights. Change out all the strips at the same time. I fixed a few of these in Trinidad.

I also believe that the backlights are bad.Where did you get the backlights from?

Re: Tcl #l32b2500

Crack open the Panel and see how many strips and how many LEDs per strip. I normally buy 32" strips with 10 LEDs per strip and have them as my stock. These strips I use on every backlight replacement I have to do and even up to 50". I usually change out all the strips as the seemingly good originals fail after a short time. There are 32" strips with 6, 7 and 8 LEDs per strip. I buy them new off e-bay from a China supplier.

Do you have the link to the seller? Thanks.

Re: Tcl #l32b2500

No. I don't have a direct link to the Supplier. I just type in the search box on e-bay 'Universal LED strips' and all the different suppliers will come up. I have bought four (4) times from four different suppliers. All prices are about the same, I just look for the least expensive supplier at the time and place my order to them via e-bay
