Toshiba 55 55S41U Black screen no back light no picture green power light


have you checked for dry joints or blown capacitors , with a power surge depending what kind voltage or amperage the circuit received it might have even blown screen connect it will certainly fry a lot of components ,have you looked for holes in capacitors ,resistors or burnt tracks between components . that's about all I can think of to check also some power panels have built in fuses to stop surges if you could obtain a circuit diagram that should help you also you could google your query and see if you get any assistance it costs nothing and you could get your TV up and running again . All the best .

Dynex dxlcd32 tv not working


No, DX-LCD32 has a known problem with both the inverter and the CCFL lamps or, to be precise, the connections of those lamps, which tend to rust, desolder and break contact.

Doesn't mean that's the problem your TV has, but I am just noting that it is not the main board they are known to have a big problem with.

And the symptoms you describe would rather suggest a functioning main board than a bad one.

Lack of sound is probably simply because you're not having the TV on the right AV input.

Turn tv on. green light solid display, no picture or sound


The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

My LG HD tv screen suddenly went green. sound is


Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

Convergence


Did you remove 1 leg of each resistor out of circuit when you checked the resistors? sounds like thier is still one resistor open or maybe one of the new IC pins need abit more solder.
