Without image and with sound In my case, I had to replace several components on the tube board, I replaced the c706, it is 22/50v, the d777 which is just below this capacitor and an r736, it is 330r smd, and on the main board only the r346 is 220r, it It is at the output of pin 21 of the ci 301 which goes to the cn of the rgb.

Closed horizontal I replaced the c 610 and it started working normally again, the interesting thing is that I had two more, but 20 inch ones that didn't turn on, I mean they kept the red light on the front blinking, same model, I went to test the same capacitor, and the defect was also him. bf.colatino
SONY KDL-32EX405
This LCD arrived at the workshop not turning on. Check all power supplys ok, but the panel LED blinks 7 times I checked the manual which says it is the temperature of the bal plate, I went to check the heating of the ci's, I found out that the regs on the right side of the processor were heating up a lot, I followed their output and checked that they were feeding the ci sii9287bcnu which was also heating up, I removed said ci from the pci and the TV worked!! BF.COLATNO
TV SONY KV-5159B
This TV works normally but the power supply is low causing a difference in width wsound it would have to be 115v it has 100v hence the problem, I have already changed the capacitors (c410,c411,c622,c623,c624,c626,c603,c613,c614 of the power supply and nothing. Resolved r605 2r2 changed replaced and the TV started working normally again. BF.COLATINO
