I have a LG LED TV 55LS4500UD that no longer works after a storm. It won't turn on and no standby light. I have pics of the circuit boards. I would like to know which board to replace?


Power Issues Troubleshooting
*NOTE* LG & Vizio TVs must be plugged in for 5 minutes before it will turn on*
1. Inspect ALL Ribbons and connectors. Any tears or bad connections between boards must be replaced FIRST
2. If you have any of these boards, it should be the first board to be replaced
A) T-Con Board - Video Problems (No Video with standby light on, audio but no video, grainy, distorted, or color problems in screen)
B) X or Y Buffer Board (Plasma TVs only) - Standby light is on but no power
C) Backlight Inverter / LED Driver - No Video with standby light on
3. Main Video Board
- Standby light is on but no power
- Either video or audio does not work (if no T-Con in TV. If audio but no video it is T-Con)
4. Power Board - No power AND standby light does NOT turn on. If standby light is on try other boards above
5. Panel - No power, distorted picture, lines, slow motion, half screen, faded in / out. Panel problems are usually not worth replacing the panel.

No color


Does it have a video input? Does it have color when playing a vhs tape or dvd into the video input?

Does the set show the raster lines? Is there any snow showing on the raster?

If the set does not show color with an a/v input either then it is likely the main power supply section feeding the deflection system or the video processing is bad.

RCA sets more than a few years old are not good investments for repairs, unfortunately.

Let me know the answers to the questions above and I can give you a more precise suggestion.
 
 Good Luck

I replaced both backlight boards but still having problem with LCD TV...it is too dark and color distortion.


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.

Lg tv initialization on screen and not going on


most likely power PCB,( look for those leaky capacitors) could be the mpu , but still requires the power PCB.( check your voltages on the PCB.) Could also be the I/O PCB.

50' philips plasma tv has sound but picture is distorted


I sugest you to change the video resolution settings on the PS-3 to see if TV sets to any one resolution...if you have any other video out (analog from PS3)...connect the out to TV and check video at different resolutions. If PS3 has Deep Color settings turn it OFF.

Sony trinitron 32 in. pip no video, (raster, with audio)


What you have described there is a classic example of the jungle IC failure. Ic301 Sony p/n 8-752-101-04. A pic with no color, and lines or grainy texture in the picture. Not a project you want to tackle if you don't have the proper soldering equipment or skills. And not a costly one at a good repair shop.. Only real hurdle is getting that heavy monster into the shop. To answer your question, yes what you described there is raster. Even the salt & pepper looking screen with no real decernable image is described as raster. In fact any image generated on the CRT is raster. And yes, these sets are prone to solder joint problems, usually ring cracking in circuits that generate the most heat.
