My RCA TV 52inch HDTV makes a sizzlin sound and shuts off by itself

this model does not use a bulb, but has 3 picture tubes. Most common problem for this is bad solder connections under the high voltage transformer.

My friend had the same problem. There is some display bulb that is on its way out. They aren't cheap. Find a 2nd hand TV parts/repair shop, They usually have cheap used ones from discarded units, and will know what you need!

The tv main Tuner signal board have problems and the causes.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

Your model uses CRTs instead of a bulb. Its usually the deflection board which causes that. Thats about 180.00 for a replacement board.

Sounds simple but check your sleep timer is off.

Here at my shop we see this problem with these rca sets. The processor is seeing a command from the keyboard or the ir sensor. The most likely cause is a faulty keyboard cuircit board. And replacing is the best coarse of action. To make sure its the problem I remove the keyboard cuicit board and see if the problem goes away. I just use the remote to control the tv, u can also do this until the part arives To get the part you need to know the entire model number. It will be on the sticker in the back in small letters hd52w56yx1 or yx30 or something to that extint. i get most of my rca parts from union electroncs or just let me know and i can look up the part number for you
