Philips 55" 55PUT5801/56 Horizontal / Vertical lines Can't Post

My Philips 55"PUT5801/56 TV has horizontal and vertical lines. 6871L-4286A is the T-Con board. Following are the T-Con voltages.

  • vdd = 16.66

  • vgh odd = -6.8

  • vgh even = -6.8

  • vst = -6.8

  • vcom1 = 5.5

  • vcom2 = 5.6

  • vcc = 3.3

  • vgl2 = 0

  • vgl1 = -6.9

  • hvdd = 8.1


Findings: Two components on the T-Con ( GH16C which i believe a voltage regulator) and an IC RT5043 getting extremely hot.

I am a newbie to TV repair and trying to understand what could be the real cause. Could anyone help me with the above voltages if there is anything unusual in the readings ?

Thanks in advance

I have a similar problem with a similar TV.
Changed tcon with no positive effect. I noticed that the 2R2 and 1R5 inductors looked like it they hæve been extremely warm, so I am waiting for spares. I'll let you you know if this fixed the problem

Hi Dane ,
Thanks for your comment. I was assuming the problem could be with the T-Con and placed an order on e-bay and waiting. These two components (2R2 and 1R5) you have mentioned belongs to the power supply or the main board ?

Please give me an update here if you make any progress with the repair.

Thanks in advance
Ajith

They are located on the main board.
I have not been able to locate any errors on the power supply. (doesn't mean the are not there though)
