I have a CLT2054 and lost the power cord. I bought a new power cord but when I plug it in the light on cord goes out and TV wont come on. If I un plug cord light comes back on

I found it on amazon. here UpBright New Global DC 12V 4 Pin DIN AC DC Adapter For Sanyo CLT2054 LCD... . I hope I have helped. Cheers

sounds a lot like you lost the video driver or control board functionality. From the 'decay' of your image, with sound still working, and all else being good, you're primed for a new video controller. Are you inclined to do the repair yourself? The service manuals are hard to get online, but the local service center MIGHT sell you one.

Tries Ebay.com,Amazon.com have picture look closely.

clt2054 Sanyo vizon 20" TV
At power on my screen blinked on for a second, then went black for a minute or so, then blinked back on, this repeated. I noticed the external 12 volt dc 5 amp power supplys green light blinked on & off with the TV but it blinked off just before the TV did, indicateing that the problem was a power supply problem. Then I put the PS transformer up to my ear and could hear it buzz as it powered on each time. The buzz increased in frequency rapidly then stopped as the internal heat fuze/thermister er something, shut it off for a minute untill it reset. A person could buy a new Power Supply transformer for $14 to $40, or could try to fix their PS. But I simply hooked it up to a 12v car battery & the TV worked. On the back of the transformer is the pinout for the 12v 4 prong plug that goes into the TV. On the TV the bottom 2 pins a 12v+ & the top 2 pins are 12v negitive. Nails with the burrs filed off fit into the sockets, a strip of thin card board between the pos & neg nails for an insulator, & aligator clip jumpers on them to the battery got me a working TV. So I now know it was a power supply problem. I could follow the advice of others on this great FixYa site & try to fix my PS capacitor problem ? Or buy a new PS, or just put the TV in my 12v veggie oil diesel magic buss, er camper thingie. AND please don't send anyone $19.99 for free advice.
I hope this helps someone in somehow.

Did you bought your replacement AC Adapter on Ebay. well I bought mine on Ebay as well but you know what they're not the exact replacement. I encountered a problem with mine, because of the reverse polarity on the output power. you can fix this though, cut the output wire leading to your TV then connect the white wire with the un-shielded one and to the same on the other wire.

OK you need a volt meter to check the voltage output of your power pack as two things cause this now enough power out the pack to run your unit or the unit has a short both problems will unlight the light so you need to know if the power supply is working right first as it should say like 120 volts AC in and 12 volts DC 1000 ma out so you will need to mesure this with a volt meter. this is a common problem loading the load of the curcuit as in your TV is mor the the power pack is giving out thus shorting out the power pack of any voltage present, as the little LED light your seeing only takes 5 volts at very ittle current to light and dose not repersent the total voltage output of the power pack itself

go to radio shack get a 12 volt 1500ma power supply with I belive it is a N% plug end but any how 800 ma to 1500 ma should run this and the plug end is standard plug with plus 12 volts on the inner side and negitive on the outer case side look at the back of the TV or the old power supply it sould have info on voltags and amprage, and the plug as to inner voltage and outer voltage on the plug any old time radio shack or electronics shop should be able to help you bring in the flat screen if need be as if you know its 12 volts then It wont mater weather you use a 1000ma 1500ma 12 volt ubnaversale power pack as the tv will only use the current needed so more MA is good the only concrn you have is the right mini barrle plug and the right side of +/- voltage on that mini plug being most use + voltage in the inner most circle and - 12 volts on thje outer

Please let me know when I can get the power cord & AC adapter. I moved and lost them and cannot use my television. Thank you R. Werkheiser

I bought one on Ebay and it didn't work because the one they sale on Ebay has a reverse polarity, try fixing this, cut the output wire, the one leading to your TV, then reverse the connection, white to un-shielded wire and do the same on the remaining wire.

power adapter is failing, get a different one and see.
