Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and also check the power resistor, if values are not exact you have to replace them. These ICs are located behind the black heat sink; you can see once you open the back off the TV. The convergence board should be checked for cracked solder joints and please make sure to check the resistors as if they are shot the ICs might blow again. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. Please also make sure to turn off and unplug the TV for at least 1 hour to drain off the current from all the components especially capacitors before you perform any repairs. Also note that the TV consists of very high voltages even when it is in off condition. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Nothing comes up on tv when i turn ps3 on and controllers wont connect


Read this very carefully. Turn off your ps3 from the back. Then turn it back on wait unit the light is red. Turn on the system through the front keep holding the power on. You will hear a beep one time that just tell you that the ps3 is powering on keep holding the button until you hear the second beep this will rest your video setting. If that dosnt work call me at sony

RCA 32 in TV no picture no sound just a beeping noise TV power is on


Hello cote,

This indicates a problem in the power supply either the low voltage switching supply or the High voltage power supply. The sounds you hear is the shutdown circuit activating, I would not suggest that you try to repair this problem because of the dangers involved. I would suggest that you take it to a qualified TV repair shop. This problem should not cost you much, however it is the best choice for the problem you described.

I hope this helps,
Thank you,

My TV shut off and will not come on


This is an issue with one of your power supplys wether it be high voltage horizontal power supply or the reg power supply. The beeping noise is letting you know that it has some power but not enough to start the high voltage needed to create the picture on your tube. I would seek professional help for this issue.
