I cannot dislodge the LCD screen from the bottom frame piece. It seems stuck together with the plastic piece along the bottom edge, it is quite impossible to disengage the LCD from the frame piece. LCD Screen looks like it is pinched in that bottom frame.

Is anyone familiar with this model (Aug 2020), and has anyone been able to perform backlight LED replacement with this mode. Please let me know I am desperate.

JeanUM.

I think I can test and replace boards myself (with some guidance) if I know which one is faulty.

Thank you all in advance.

Update 6/8/2024

After a bit of hunting I found the service manual for my model TV.

Here is the link: https://research.encompass.com/SON/rr/XR...

I followed this troubleshooting diagram for the 4x blinking code, but I am getting different results with voltage readings when the TV is booting up, or TV on but blinking 4 times, or off in standby mode.

In other words I get the 3.3V or the 0V at both testing points at different power states of the TV.

So my question is, when am I supposed to be reading these voltages?

While it is booting up, after is has booted and is blinking the code, or plugged in but off in standby mode?

Which pin do I disconnect and ground to bypass six red blinking lights? Board number APDP-209A1 (Brown board). On the board there is the word "Secondary" with an arrow pointing; (CN6401-8) BL_ERR.

I assume this is the pin I want to disconnect and ground. Do I count from the top? Does secondary mean it's on the bottom and not the top of the plug since there are two wires for each position?

I removed the eighth pin counting from the top down on the upper row and it prevented my TV from powering on.

The issue is exactly what is written in the title, the right half of the screen has unsaturated colors.

I dont know when or how this happened as I bought it off a guy.

I've tried factory reset, software update, tweaking the settings. Nothing works, so it is a hardware problem. But I need to know exactly what is causing this so I can replace it.

The first image is how the colors should look and the second is how it look on the TV.

I have a Sony Bravia KDL-42W705B purchased Jan 2015.

When I turn it on I now get a full screen of blank light Blue and no sound.

Sony says you may reset the TV settings to the factory default but I can,t as there is no menu or home button due to No picture. Anyone help as SONY say it is out of the one year warranty and they are not liable for any repairs.

Its a disgrace, I will never buy SONY again and will advise others to follow suit.

Surely A TV should last more than 18 months

I have tried a power reset without success Jayeff thanks though.

I have attached a photo of the blue screen Oldturkey03,

Hope this helps

Sony Bravia Model No: KDL-47W805A

Only yesterday a number of horizontal lines appeared on my TV screen, only the lower 1/3 portion of the screen though. They intermittently flicker between 1/3 of the screen having visible lines to only the top three of four lines.

I have attached two pictures below which I hope go some way to demonstrating the issue.

So far I have:

1: Switched the TV off for a period of time and then switched it back on - The lines still appear.

2: Removed all the connecting cables (Amazon, HDMI, Cable) and then switched it back on again - The lines still appear.

3: Conducted a factory reset - The lines still appear.

4: Applied pressure along the edges of the TV where the lines appear - No change, the lines are still visible, no distortion to them. Although this might seem strange I read somewhere that if there is a loose connection along the LCD connectors applying pressure might confirm this is the lines change with the application of pressure.

5: Given up :(

Sony Bravia Model: KD-55X7400H

Software version: 60434,

Btw, the TV is 5 years old. And the repair was not done at Sony service centre.

My TV (Sony Bravia KD-60X690E) suddenly doesn’t turn on. It’s only about 2 years old. When I try to turn it on the only thing that happens is the stand-by light flashes red twice. I’ve already done some research and saw that this is usually a power board issue. I got myself a multimeter and started reading voltages and this is what I’ve found so far:

With the TV plugged in I have 5v to standby (expected)

I don’t have voltages to anything else until I try to turn on the TV, then I have voltage for about a second or two before it dies off. All of the voltages looked fine except in 2 areas

1. None of the areas that should give 12v to tcon (there were 3) had any voltage being sent. So looking at the image that would be the smaller bottom plug number 3 and 4, and the 1 tcon 12v on the larger plug
2. The LED was suppose to get 155v, but was getting 120v

What does this mean? Is the power board need replacing? The board was a little dusty but didn’t see anything else that looked wrong (but I haven’t tested any of the components) Thanks
