If you have sound and no video, try connecting the TV to your DVD player to see if it shows a pitcher, if not, or if it does the problem is more likely to be your T-Con Board. Get one at shop Jimmy.com

Rca led32b30rq pictures flickers


This is the common problem with this model of RCA TV, the problem is not defective LED strips, but the power supply.

You may purchase a power supply on the net, but you can't guaranty that it is a good one.

This is the trick to make this TV work:

On the power supply, locate the R410 100K resister, solder a 220K/0.125W resistor in parallel with it, this will race up the oscillation frequency of the back light power supply circuit & make the voltage stable.

It is not a proper service procedure, but it works for us.

Tv turn on no picture


If the sound still works normally but the screen is dark then I would suspect the inverter for having the issue. If you dont have sound either then I would check both the power board and the main board.

Show a torch light on the screen (not too close) when the TV and program is running. If you can see the picture, the backlights have gone off. Anyhow, the TV needs attention by a qualified service technician.
