Use a cell phone camera to check the remote control. Point the camera at the remote and try the buttons on the remote and look for a flash of purple light on the camera display. The remote might have some bad pads on the membrane switch. On the set unit buttons, the issue could be the soft pads on the inside of the switch, they use a carbon impregnated pad and it is either dirty or worn out.

El Tv tiene que encenderse primero manualmente.

SOURCE: my rca tv/dvd combo model# 20F514TD will not turn

Could be the frount panel with the remote infered gone out. There is a little I beleave 16 V 1800Uf cap on that board check it and see if it has bulged or it leaked. It also could be a IC intergraded circuit gone bad. Its hard to tell without looking at it.

We have a 46la45rq RCA TV. The input button on the remote bring up the options but it continuously scrolls. The side buttons do not work either (no signal) Do you think it is the t-con board?


Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. In some cases, the remote control might need to clean.

I have a RCA LCD TV and the power button and volume bottons don't work on the tv. Which board do I need to replace? Model number is 46LA45RQ


If these functions can be done by using its remote control, and only the front panel buttons are inactive, microswtches at the front panel board should be replaced. If functions are not available with a remote control too, the main board is faulty. If you wish to get some details; check the site linked here. Pull up older posts.
