Hello Sidney, so you comment, your Sansui would have problems in the back lighting of the LCD panel (BackLight)
Usually one or more LEDs are burned, this causes the lighting system and the TV to be interrupted, it keeps the screen dark and with sound
You should replace all the LEDs, to ensure a repair that lasts longer, because if you only replace the burns,
at any time another of the originals is burned and you have to do the work again, with the risk of breaking the LCD panel
I hope you can solve the problem, comment the results
Greetings Franco Dosil
Hola Sidney, por lo que comentas, tu Sansui tendr?a problemas en la iluminaci?n trasera del panel LCD (BackLight)
Por lo general se queman uno o mas Leds, esto hace que se interrumpa el sistema de iluminaci?n y el TV, se queda con la pantalla oscura y con sonido
Deber?as reemplazar la totalidad de los Led, para asegurar un reparaci?n que dure mas tiempo, porque si solo reemplazas los quemados,
en cualquier momento se quema otro de los originales y tienes que hacer el trabajo nuevamente, con el riesgo de romper el panel LCD
Espero puedas resolver el problema, comenta los resultados

SOURCE: TV picture is red.
Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.
SOURCE: Sansui led sty0632 has no picture or sound and horizontal line on the right
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.
