After the main board replacement, there are some adjustments should be done. Sometimes, the firmware update too might be necessary. There are service adjustments too. Contact any service technician.

Hi again,

Sorry bout the Live Session.

May I suggest something?
Pls try another signal source other than the indoor antenna such as a DVD or even an old VCR.

It is possible that what you are experiencing is video muting due to dirty antenna signal. If even with a stable known to be good video source (DVD) the problem persist, then it is a matter of checking the voltages as indicated in your service manual.

Hope this be of some help/idea even if the chat did not work out. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: distorted picture on RCA LCD TV

I have the same tv. Had repair man come to my home in late april. Said it is the power convergence board. $225 for parts and labor I was told. Bad thing is part was supposed to arrive mid-may,then mid-june and now mid-july. He say's part is on back order. I'm actually going to contact RCA soon to find out if this is true. This seems to be a common problem with this particular T.V

SOURCE: 5 year old RCA 50 inch projection tv. Picture went off.

If you are using component cables make sure they are all connected properly( pushed all the way in and in the correct input). I have seen the red cable come loose several times and cause no red color in the picture. When you change the lamp it is easy to pull on one of those cables and cause it to come loose.

I have a RCA TV LED39B45RQ - I have replaced both the boards and still get nothing but a red light ! any thoughts ? Thanks


What boards did you replace? Not knowing what you did it seems tv set is dead and that it just may be a power supply issue, a common ailment.

TV has red light but no picture. It appears to not power on.


It probably got zapped with power. Regardless of how it broke, the first place to start is the main power supply board. Some people repair the caps, which without looking more in depth at some of the troubleshooting forums, I couldn't tell you which one is most often the culprit. It looks like the power supply boards are going for about $25 on ebay, and I would feel pretty confident replacing that at that price.
If that does not fix it, something on the main board could be "crowbarring", or sapping power from power supply from where it is needed to boot up, however, that would only be a secondary test to making sure our power supply is a good one.

I have a rca model 40LA45RQ that will not turn on. When you hit the power button the light turns blue but no picture or sound. I tried replacing the power supply board and that did not fix it.


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
