Sanyo vizon lcd clt2054 tv

The tv will not turn on for more than a split second. The screen then goes dark for several seconds, on for a second, off for several seconds and the cycle continues. Attempting all the electrical solutions such as checking cables and unplugging and replugging does not help. What is wrong and is it repairable? The TV is just over 2 years old. 2 other people have posted the same complaint. Solution? Thank you!

Hello,

if the Tv has no power at all you need to test it in series. beginning from the power input to the TV projection circuit.

Open you TV and then check the power input maybe fuse blown out, or some parts it busted. (note: only the expert tech can do this job) however if you can do the job then, be carefull for some high voltage inside.

may this help, melnavz

Lot of possibilities so start with the most common source of trouble namely the horizontal amp transistor , after that is the flyback transformer which is driven by the horiz amp transistor, hopefully both are not faulty !. Bear in mind when testing the transistor with a multi meter ( on diode test ) that there is an internal diode connected between collector and emitter, You could also simply connect your meter ( on ohms like 50k ) red lead on collector and black lead to chassis ! The reading should be over 10 kohms , if it is a lot lower then either it is shorted or the transformer is, See how you go from here !!

Please update me on this

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.

Sanyo Vison model CLT2054 - three years old. Screen goes black shortly after turning it on. Is this a common problem? Is there an inexpensive fix?


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.

Sanyo lcd tv flat


I have researched this problem and it is so common we that own this piece of junk ought to form a class action suit and sue. It is caused by a bad part or bad connections to a part called a backlight inverter. It seems the LCD needs a higher voltage than supplied by the 12vdc power pack so this part re-chops the DC voltage to generate the LCD requirement.

The date of manufacture is on the back of these TVs and all the problems seem to be from those made in 2006 to 2008
