Yes, I do not need a purchase and find out what voltage is on the connector circled in red. And you bought me where to buy immediately. It is better to write where and how many volts on what legs or pentacles that's what I need
Yes, here I am restoring bp after a short circuit and I wanted to know how much voltage should be. Only it is unclear from the mine to measure or without it?
Because eq. KDL-42W650A have LED strip T42-40-L (left) / and T42-40-R (right)
All strip have 40-Led"s , each LED Uf=3-3.6V
... that is, the voltage must be at least 144V

Panel: T420HVF06.0 xxxxG
LED backlight: 74.42T35.OO1-0-DX1, T42-40-R and T42-40-L
tell me the Sony TV kdl42w706b sony I put the lane there from kdl42w817b and that you need to change the firmware, change the size of the matrix. If you change the firmware, give the firmware or the link where you can download it
I have been getting this problem put the lanes on 42w817 kdl on kdl 42w705b TV blinks times ripples may sound then appears error 9 tuc.When you disable the t-con and run all the rules and if you pick up on the hot t-con it shows.Flash tried not sewn. I understand from Mein 817 3d and 705 normal as you can correct in the service menu to change something??????
The discussion revolves around the required voltage at the power connector for the Sony KDL-42W706B LED TV, specifically concerning the LED driver model 14STM4250AD-6S01. Users inquire about the voltage specifications needed for proper operation, with one participant noting that the KDL-42W650A model requires a minimum of 144V for its LED strips, which may be applicable to the KDL-42W706B as well. There are also questions about whether the LED driver can be tested independently of the main board and how to address issues related to firmware and compatibility with other models like the KDL-42W817B. The conversation highlights the complexity of servicing these models and the need for precise voltage measurements. Summary generated by the language model.
It's impossible, let's see, after the signals necessary for proper operation of pcb inv.
