Finlux tv showing black screen after switching on by remote. standby light is flashing buy mo picture or sound


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

No picture, just sound on Etec Flat Panel 40A99


Video circuit is separate from the Audio circuit. The main controller may switch to Audio, but if the unit is damaged from a power outage; part of the circuit board may not function. Needs professional servicing.

A brief history: fixya helped me change my bulb (been receiving a "replace bulb" message for awhile until my picture went black). The picture now is snow, not black which seems to me to indicate the bulb...


Since you do have sound but snow for picture is your TV 54J or 54U chassis the PT50DL54J chassis shows 4 tuners also Have you look for Leaky or Bad capacitors if they are puffed up on top they are Bad 2200uf 25v 1000uf 25v Look for bad capacitors on tuner Boards, and I have seen where they are on Power supply board that will affect Picture.

Audio only, no picture


Audio without video is usally a vertical or horizontal deflection problem with the DPTV chassis and Mag 1 chassis which is what you have. You may need a new deflection Large signal board. If you would like a link to one of those boards let me know.

Tv has sound but no picture


Sounds like you have lost video somewhere in the video circuits. Possibly the picture tube could have gone bad or lost filiament voltage. You can check to see if you have high voltage by holding your bare arm close to the screen. The hairs will stand up if you have high voltage. Absence of high voltage will also cause a black screen,but the sound might not work either since on some sets the power for the sound is supplied from the same circuit as the high voltage. Stargazer

Video will not turn off; "I2C-BUS STOP MODE" error at power up


Nope a very easy problem .. What it is is the relay is stuck on or closed so when you plug in the set the power comes up But the micro hasent told the rest of the set to work yet. So when you hit the power button. its just like you hit the power and it activated the relay and the rest of the set. Now in some rare occasions the driver transistor for the relay was shorted But most of the time its the contacts that weild shut, but you cant just clean them as it will work for a while, but in a month or so you will be in the smame boat. But if you not a tech this repair shouldnt cost you to much because if your not an experienced tech you can not only cause harn to the set but also you yourself BE CAREFULL and take the set to a pro!!!! Good Luck
