Question about Emerson EWL3706 37 in. LCD Television

2 Answers

I still have not solve my problem. I know the lamps are still okay. I need a opinion what's causing the shutdown when I power on my TV. I have a Emerson LCD color tv, M/N-LC320EM82 that when it powered ON remotely or using the key, the green light blinks 4 times and I see the screen with the "DIGITAL TELEVISION" writting on it but it will go back to standby mode. I did contacted FUNAI 3 times for any inputs to no avail. Perhaps if I have a way to pin point which boards are the problem, I can just replace the board. I am not a electronic technician that can test every single parts to pin point the problem to just unsolder and resolder parts. If someone had experienced same symtoms and they fix the problem, I would be really glad to know. I checked Shopjimmy.com for parts but unfortunately he has every components of my particular unit except for the "power supply/ backlight inverter" with part #BA71F0F01042.

    I've found a Service manual that I paid 10.88$. The service manual don't have a troubleshooting guide. it consist of wiring and schematics, some warnings and parts list. I don't think this will help me at all. I acquired the service manual from NY TECH TV repair, INC. is this common to Service manuals? I thought a service manuals consist of everything to fix or service a particular unit.

Hello, if your a slight bit electronicaly and mechanicaly inclined then its a matter of finding your tv's service manual. in this manual you will find the cuase of the specific model codes 4 blinks .
since all tv's have different component they are different to trouble shoot not all codes mean the same thing to all tv's,. each company has there own trouble shooting codes.
basically you will have to find the manual it is downlaodable at service manual sites or parts zone
then you will have to read a bit to get familiar with your tv's circut shutdown procedure
it should be a board if your getting blinking codes thats a good thing your tv is servicable.
dont pe impatient take your time and locate a manual.. when you know what part to exchange according to the blink codes then you go on ebay or any parts site and find the part its not to hard just a bit complicated and it takes time to find a inexpensive usable part but it will be rewarding.
i am a electronic tech and i still have to get the manuals before i start to fix a set i have fixed a few of them and the rewards is seeing it go back to life without spending as much as a new tv to fix them like electronic repair shops they want 400$ just to look at your set and exchange 1 part so do your math and get the manual first.. ..

then you will know.. good luck best regards

Replaced the lamp in my Samsung DLP Model # HLN507W know I have no power except the blinking green and red in front of the tv


Did u leave fingerprints or natural oils on the lamp? Wipe the bulb off clean. A dirty bulb especially with fingerprints will overheat and will shutdown as a failsafe. Make sure the lamp is the correct part for the tv.

Benq MX761 stays on for only 2 minutes and then shuts down after genuine Benq lamp replacement. Picture flickers colour just before shutdown. Lamp timer has been reset to zero.


Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If you see any, replace them all in the power board section. Check to see if your TV is still under warranty first though.

Sounds like you have something causing your set to go into "shutdown". A number of things could cause this! Possibly you have a bad solder joint which causes an "over voltage" condition. Stargazer
