    I get green blotches on my Samsung 42" HDTV. When I turn it on it, the whole screen goes green, then the picture comes on but with green blotches running especially where white color should be. Anyone can help?

You need to repower the cable box. That should fix it.
Good Luck

SOURCE: green screen

Try doing a "factory reset". This will "burp the baby". Turn the set on and ignore what you see. From the side control panel, push the volume+ and channel+ buttons in synch. This will take you to a base OSD (on-screen display) that can best be compared to the BIOS on your PC. The real goodies are here.

On the OSD, you'll see "picture", "audio", and "advance". Using standard navigational input on the remote, go to "advance". Tab down to "clear all". The set will appear to turn off, but the front LED will remain blue. The set is re-formatting the on-board memory and will restart in a few seconds.

Your panel should now restart as normal, but will be returned to factory "burn-in defaults". Your color and audio adjustments will be lost, so you'll have to do some fine-tuning in the regular OSD menu. Cycle power to the TV after you have made the desired adjustments.

TIP: Perform the factory re-set a second time, then select "picture". Toggle down to "video format". You might find it set to "Pal". Change this, using standard navigational input on the remote, to "NTCS" or "AUTO". Cycle power to the TV after you have made the desired adjustments. The TV will now perform at a refresh rate of 60hz, the American standard. "Pal" is 50hz, the EU and Asian standard. The improvement to image quality will be noticable very soon, as both your eyes and the set adapt to 9.94 hz improvement. NOTE: You may need to fine-tune the TV again after making this change.

Tv does not turn on


If green light flashes more than 8 times, it could be as simple as repairing or replacing the power supply. Unplug the TV ,remove the back. Look for bulged or leaking capacitors on the power supply. Do it yourselfer? only if you have soldering skills, or purchase replacement board. remember, used boards are just as old as your failed board, buy new or rebuilt, Good Luck

House struck by lightning and no picture in tv


I am so sorry but you should have claimed that on insurance. The amount of damage to all the solid state items in that set would mean that you are going to be replacing everything.

My Magnavox TV give sound but no picture. When I turn it on the light in the bottom right hand screen goes green, then flashes to yellow and goes back to green. The screen does not change it is constantly...


You need to replace your backlight inverter.

Check that all voltages are coming from the power supply as they should. The power supply will be stamped with the correct amounts, and you just read with the multimeter to confirm.

After those check out ok, you will need to replace the inverter to "light" your screen again.


You can hear sound because the tv is ON, but the inverter isn't lighting the screen!


Hope this helps, please rate!

Screen goes black but still sound


This is inverter or backlighting problem. Can you try switching it on and off quickly for a couple of times and tell me if these '2 seconds' get any longer'. If picture stays longer and longer before shutting down, one lamp needs replaced-if not, please replace inverter board

Green power light comes on, the turns right back off. No picture. Please help


I'm not sure what TV model you have. But, thing I can tell you is the most common problem.
Most of the time with flat panel TVs, the power supply for the screen fails. And the TV normally turns itself off to protect other parts in the TV from being damaged. Basically " Protection Mode".

You can try leaving the TV unplugged for 30 minutes so the TV can reset itself; then try again turning it on. If it doesn't work after that, it's time for the TV repair shop.
