Chosen Solution
Hi all, My sony bravia ( 4 years old)was giving me picture disortion, ghosting and horizontal lines in the upper side of the screen. I will add a picture of this. it is a sony bravia kdl40hx850 serie This is what i did : i did a self test : was ok. then i took a look a the main menu : the picture was the same , so lines and disortion trough the menu as well. ( so i asume no BAPS problem? ) i opened the back panel and moved ( gently wiggeld ) the lvds ( lcd ) cable that is connected to the T con board. the screen turned a little pink, but still the same problem. I checked the golden thin flat cables connecting the lcd panel as well , but nothing changed. i ckecked all the pcb’s for leaking chips or transistors and condensators ( or blown condensaotrs) but no visible damage. after doing this , i tried the tv to power up. i didn’t get picture only 5 times a blinking red dot at the stand by dot ( in the service manual i read that it could be a t con error, lvds cable error or a p_id_err panel: eeprom 12 c nack error ( so a reading error on a chip i asume? ) ( i tried to check the diodes but it didnt work.. no measurement… did i do something wrong? ) than after all this i checked the voltage on the g6 board ( power board or static convertor board) i measure 4.2 variable ( between 3.0 and 4.2) volts dc on the powercable tot the t con board. this has to be 12 v dc. here stops my knowledge… is there a solution or does someone knows what caused this problem(s) did i do something wrong? ( diode check.. or ..) if i take a look to the troubleshooting page in the service manual i see 1 possible problem and this is the lvds cable.. but all the rest have to work than .. ? the spare parts for this are ridiculous expensive in europe.. i don’t know why… ( a t con board about 300 dollar ( 278 euro) and a g6 static convertor ( 190 euro ( about 210 dollar) and the lvds cable 100 dollar.. thanks in advance and sorry for my incorrectly english..
