Greetings yoreparo friends I have this fault, this TV came unlit with a short in d807 and r815 change these components the tv turns on but with this novelty. I tell you that D807 was an Rgp15j and replace it with a uf3002. I don't know this fault since I don't have much experience I hope you can help me.

the tv is in video function, if you want to see an air signal, you must change the function, an air signal .... greetings.

friend. In addition to what the UF 3002 diode tells you, it does not appear as a replacement for the rgp15j diode

Magnificent observation of manolo, although the diode at the moment is not the cause of its failure, it will be later, I replace a diode although it is also ultra fast and corresponds to the amperage, not so to the inverse voltage that is only 70v, change the diode for another equal or higher .... greetings.

"Turn on but don't give image"
You show us a photograph of the TV, where you can see that the OSD indicates that it is in VIDEO mode.
Do you have a DVD connected? .... Is the audio heard ?.
Does it look normal by TV Air mode (ANTENNA)?

It is correct to turn on osd and there is also audio but the image both on video and antenna look the same. Already change the diode place egp20j and also change the EPROM if results.

The processing of the video signal, both of ANTENNA and that of the EXTERNAL VIDEO input is done internally in the ICs ... polarization around it and the Q701.
Observe on the card or mainboard that there is no loose or damaged connection element or track, RECTIFY WELDS of doubtful appearance or in poor condition.
Finally, place a new EEPROM previously recorded with the parameters of. the brand and model

In the photo, I notice the entire screen illuminated in a blue tone.
Does it look blue or is it dark?

Now yes, it is better appreciated and with more details ....
Does it look the same with those diagonal stripes in A / V IN. ??
We change course and go to the synchronism, oscillator, driver, horizontal output and AFC separator.
Check the good condition of the components in the AFC line as they travel to the respective pin in the jungle IC.

Ready friend thanks for your input the fault was in transistor q801 a KTC3205. I was short, I replaced it and tried the competitors around and that's it.

Thank you for sharing the Q801 solution: KTC3205 = Sw-8v-Reg (8v switch).
Congratulations !!!

Hello Friend. if the fault is the cause of the fault, place any of these egp20j or you can have the k, mur260, mur280, her208, her206, sf207, sf29, sf27, ru20a, ru30a, rgp30j, egp15j or with k bym36c, by299 all these are diode replacements rgp15j. Cheers

Ok I'm going to change the diode, I think that in air it also looks the same. I appreciate your help. I change it and tell them.

Friend Manolo already change the diode and also the EPROM memory forget to tell you that I have audio and the fault is presented in both video and antenna.

colleague: raise the screen a little and see if it illuminates the screen ... the screen is the potentiometer q, it is on the bottom of the fli-bak ... turn it a little to the right and see if the screen illuminates .. .If it does not give results measure q, tension has on pin33 (ABL) of the lc (101) must come about 3.5v .... measure tension in the cathodes of the tube R910-911-912 ... measure q, tension you have on pin8 of the fli-bak ABL .... exit the video option and see if you can enter the option air channels or catv ... see if all the options appear in the user menu ... OSD. ..Cheers!!
