The tv turns on normal. These are the voltages. Gnd = 0 Video = 2.3 vlts NC4 = 3.5 vlts SIF = 2.4 vlts NC3 = 0 SDA = 3.3 vlts SCL = 3.3 volts AGC = 3.3 vlts, I think it is not correct. B = 5.0 volts The other two are NC. The TV does not tune channels but cn DVD if the image looks good. Please help

Hello, the tuning voltage (30v approx.) Is this? - In agc without signal it should be 7v. approx.

If it is not correct my contribution excuse me. Pretend I didn't say anything. I am not an expert on these TVs. Not in the others. Haha. I only understand something.

Hi. That tv is not conventional right? If it is not, you should ask the question in the appropriate forum. not commented on if you did self-programming. reading a little I saw that tuner IS 12 pin and more or less carries these tensions. PIN1 15.27V, PIN2 15.27V, PIN3 0.00V, PIN4 O, OOV, PIN5 3.49V, PIN6 3.49V, PIN7 0.0V, PIN8 0.0V, PIN9 0.0V, PIN10 O, O9V, PIN11 0,0V, PIN12 0,01V
