LCD, LED, OR PLASMA.
If plasma, you will have to replace the Y-sustain board buffers.
Else, need to trace the power supply to XYZ

kcs36dd, Lcd TV's also have, just like LCD monitors, an AC to DC voltage power supply. It is called a "switch-mode-power-supply" and generates the DC voltages required for all the other important electronic circuits inside the unit. 98% of all 14" to 22' lcd panels have backlighting provided by "cold-cathode-fluorescent-lamps" (CCFL) that produce WHITE LIGHT so you can see all the pretty colors that the glass LCD PANEL produces on the screen. The INVERTER circuit requires 12vdc to 20vdc from the SMPS to convert into 500 to 1000v ac to light-up the CCFL's. IF the SMPS detects a FAULT CONDITION with itself or the INVERTER it will go into what is known as FULL or PARTIAL SHUTDOWN MODE to try and save itself from a catastrophic, nonrecoverable failure. e.g. sparks, smoke, fire. lmistyrel on aim.com I could give you more assistance if you had provided following informatiom.
1. How old is the unit? 2, Approximate total "ON" hours unit has? 3.Has unit failed within the WARRANTY period? 4. Will SAMSUNG do a cash+old unit swapout because of PREMATURE FAILURE? 4. Do you know enough to do a unit TEARDOWN and inspection to possibly determine ROOT CAUSE of SMPS/INVERTER failure? 5. Can you handle a soldering iron and solder to make DIY repairs to unit. 6. Since your unit is just a little more complex than a LCD MONITOR, have toy viewed on YOUTUBE short video clips of "LCD monitor disassembly" or "LCD monitor repair" for the most common cause of BLACK screen complaints? If further assistance is required do additional post to original. 12fixlouie aka louie12fix on fixya

No picture, no menu, black screen, no raster, sound ok


From your detailed description, it sounds that the main chroma processor IC has damaged. Raster means nothing, but the lighted screen that appears, when a TV is switched ON. For some brands, there will be a blue screen; when there is no signal input, and some others will have a bright white screen with some snow.
I advice you to contact any service technician, to get this TV repaired. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

Picture tube


what kind of display have, totally black or only a raster?. if you are watching a local channel then only a raster with sound, it could be a tuner problem. now if totally black screen you need to check if the flyback transformer has high voltage coming out at the anode cap. and then the tube has heater light. this case can be hand held with a trained technician if you don'y have an idea on how to deal with it just leave it to the tv technician for safety reason. however at least you have an idea what to expect if you decide to hire for somebody to fix.

No picture, only sound on LG 47LV5500: how do I get picture back?


Definitely odd for sound to come through and not sound, especially via an HDMI connection.

I would contact LG for support, your TV could be defective.

Good luck

Lg 37le2r will only show black and white picture. Checked antenna ok.


I've encountered that experience before it needs some technical knowledge because the raster for rgb on your lcd is going bad and the video signal out put cable is mis aligned get someone to re align the raster and your video signal output cable
