djreynolds, maybe go look for some clues at YOUTUBE and search for videos that are longer than 6 minutes and use search term "LCD monitor disassembly" and "LCD monitor repair" may turn up something!! Also find a very DULL butter knife to prevent visit to emergency entrance of local hospital when "PARTING" the rear plastic cover from the front bezel. Use extreme caution to prevent damage to LCD PANEL. 12fixlouie

SOURCE: I have an RCA DLP M50WH72S tv. Powers up, picture

Hello; I am John at J D Electronics in Poland Maine. I have had an RCA model M50WH72S setting dead in my shop for over a year now and is now mine. The set would start intermittently and run for an hour and die. Other times it would not start at all and the LED would flash 5 or 6 times and stop. With no support from Thomson/ RCA, I was on my own. The extended warranty Co said to try the light engine first. I replaced the light engine with no improvement, just the led flashing. I was not going to pay 500 to 700 dollars for other boards to try to fix this piece of JUNK.I have since read several blogs that point to power supply caps as being the problem. I took this piece of junk apart for the last time before I hauled it to the dump. I pulled out the power supply on the left as you face the back of set. I noticed 2 Electrolytic caps had " domed shaped tops ,which is a good sign of failure or overheating. They are 1000 ufd @ 35Volts 105 degree rating. They were both bad along with 2 more on the same board ! They are labeled CP624 and CP647 on the bottom edge of the board inside the "c" shaped heat sink. The other two are above the chopper transformer labeled CP641 @ CP639. replacing these fixed the set. Call DigiKey 800-344-4539 part # 493-1588 are ten for $7.00. Don't spend money on a lamp you don't need.

I have a RCA 32" Flat TV that when plug the power light comes on,but not the screen


Try the flashlight test to see if everything is working but the lights in the panel, if you don't know how to do that google LED LCD TV flashlight test and post your results then its easier to give a better idea of what the issues are.

How to turn off internal speakers on rca led55g55r120q tv


You can't normally if using the HDMI cable, although you could check in Settings - Sound. The small 3.5mm jack usually has a mute for the internal speakers.

Your manual doesn't mention it, so no you can't. RCA are inexpensive basic sets.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

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.

Blank screen on LCD TV


either the backlight power board or the power board itself isn't powering up the backlight power board

or your backlights are burnt... this is where testing comes in

Sound no picture


Its a common problem for this model.
1. Is there any flash of light from the backlights (best viewed from the back of the TV with the back removed)?

2. Have you tried shining a flashlight on the screen to see if a display is present when power up?

There are three possible failures.

1. A failure in the main board.

2. A failure in the LCD panel / Tcon

3. A failure in the inverter / backlight system. This could be as simple as a blown fuse.

Thos three failures would mean it needs to be service.call RCA

Bad backlight inverter on 42" RCA LCD


Does the backllght go out after a few seconds? Could still be a lamp or something else on the inverter boards. You could try used inverter boards from the same set with other problems (broken screen), Or a complete working backlight from another set but very delicate operation to swap the LCD display from one panel to another.
