Sharp LC-60LE650U
I have a Sharp LC-60LE650U that shuts on and off with only Sharp logo displaying before it goes off then repeats. When the tv is powered on the standby light is blinks once then goes off for a count of 2 then then repeats same. I could use a schematic for this model if available.

Re: LG 55LV5500-UA no picture or sound
I thought I would give you an update on the tv repair. The tv is fully working now with no problems. The main problem was the BCM (IC101) was whiskered (wouldn't give the 3.3V on the output to the LVDS on pin 7) & needed a reflow. I preheated the board to 200 C & then slowly increased the temperature on the IC until 220 C for 15 seconds.

Re: LG 55LV5500-UA no picture or sound
The t-con fuse resistance reading was 12.87 kilo ohms. Does that mean it is bad?

Re: LG 55LV5500-UA no picture or sound
After finding the board service schematics I did the additional tests as follows.
1.) Checked stand by voltage on (P501 pin 9-12 +5.5V) GOOD
2.) Checked micom voltage (IC602 pin 48 +3.5v) GOOD
3.) Checked (P501 PWR_ON 1-pin 3.3V) GOOD
4.) Checked multi voltage (P501 2-pin: 24V, 17-pin: 12v) GOOD
5.) Checked (IC501: 0.9V, IC504: 2.5V, IC505: 3.3V, IC508: 1.5V) GOOD
6.) Checked (Q507: 12V) NOT GOOD BURNED WITH A BUBBLE ON TOP
7.) Couldn't check inverter control P501 pin-18 because of previous...

Re: LG 55LV5500-UA no picture or sound
I found out the part is a "P-Channel Enhancement Mode Field Effect Transistor" & is located in the "panel power" section on the main board. I do not have one of these on hand to replace to see what will happen.

Re: LG 55LV5500-UA no picture or sound
I will check the ribbon cable pins under magnification & will report back. The menu doesn't show either. I did find one possible cause though when I was searching the back of the main input board. I found a burned 3-pin chip with the markings (X75A) with (16) written under it. I will upload a picture of it tomorrow.

Re: LG 55LV5500-UA no picture or sound
I went back & made sure the ribbon cables were properly seated & still no LG logo displayed on the screen. The backlights stay on but that is it.

Re: LG 55LV5500-UA no picture or sound
I disconnected each ribbon cable going to the screen & nothing was displayed. The backlights stayed on & now the LG logo no longer shows on the set when turned on.

T-con smd fuse both sides 10.91 V
Starting from the lower left power ic:
1.) 12.50V at turn on then 1.6V
2.) 12.50V at turn on then 1.5V
3.) 12.50V at turn on then 1.3V
4.) 12.7V at turn on then 1.3V
5.) 12.8V at turn on then 1.3V
