20 Most Recent Sanyo AVM-1909S TV Questions & Answers


Hello
The buzzing sound from your TV indicates that it LOY [Line Output Tranformer] has damaged. You have to open your tv and must have some knoledge in electoncis to retify this fault. Whe LOT said above is replaced, you have to replace its drive transistor also. Whe LOT getd damaged, the transistor that drives that will also get dameged. Therefore, when we replce the LOT, we have to replace the drive transistor also.
You just replace the its drive transistor first. After replacing it, just switch ON the Tv for a short time, say about 30 seconds or so, swtich it OFF, unplug it from mains supply, and check the heat of the above said transistor by bare figure touch. It may get warm, but not hot. If it overheats, it is an indication for you that the LOT is damaged and must be replaced wit same type annd number.
The horizontal out put transistor can be located very nere to LOT, and a three terminal component, look like a power transistor screwed on to a metal plate to radiate heat away from it, will be very close to the above said LOT.
Replace it first, and see the effect. If you wants further assistance frome me, get me through Fixya. Ok.

I had a problem like that so I disabled the tv's onboard tuner (input source)and now we use the cablebox's video and audio out to the video and video in jacks on the TV this will work as long as you have a cable box or sat reciever for your video and audio source and of course your TV must have video and audio inputs so it will work.

Good luck Rich

Hi I read your problem with the Sanyo PLV-55wm1. It sounds to me like a power supply problem. Like most new electronics devices, they use a switched mode power supply (SMPS)to supply the voltages to the rest of the set. Many of them use a current feedback loop to sense a short in the circuits that it powers. I would check for a shorted diode in the high voltage section of the tv. If any one of the components is shorted around the high voltage circuit, The current control line will be zero forcing the regulator to shut down.

probably you need to replace the picture tube or maybe theres a loosed connection in the high voltage circuit or the video circuit due to the fall. if the picture tube is the problem, you better buy a new tv coz replacing it is not practical and economical. but if it is only loosed connection just bring it to a qualified technician for sure he will not charge you too much for this problem. good luck!

Again;The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
