Question about Sansui DTV2760 27" TV

2 Answers

Sansui SV2918 has no picture and audio only a blue screen

When you switch on the television, you only get a blue screen. No audio and no picture. I have tried to surch for channels but there is none. It is not brand new and has the channels already programmed onto it but recently lost the picture. Please inform me on what could be wrong.

My SANSUI tv model SV2918 pictures are waving right to left or left to right. Kindly let me know the fault I will fix it. I love Sansui. S. Muyambango, Zambia


Glad someone loves SANSUI...cause I don't, In my opinion they're a poorly engineered TV with lots of issues. What your describing sounds like a pincushion issue, if you have the service manual check various voltages in that circuit, without seeing a picture of what its doing that is only a guess however..

No heater for tv model no.SV2918


Check the continuity of the CRT heater [pin 1~8]. If it is found open, no need to proceed. If it has continuity, check the AC voltage there when the LOT works. Should have about 6.2VAC. If not, check all the solder terminals and series resisotr. connected to this bus. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

I have a sansui tv model sv2918,it doesn't play


The TV has some firmware defect. Seek tech support.
Unplug it from AC mains wall socket, and plug it again after 5 minutes. This must make it a hard reset.
