Re: Toshiba 55g300u. Picture goes on and off but sounds remains
Hello Again. I'm sorry I've haven't had the time to resolve this issue earlier. aaronwt6, i opened the back of the tv and did reseat all of the connections on the inverter board on the left side. I've attached some pictures for your reference. The inverter board i checked is to the left side. I also reseated the connections to the tcon board shown on the top part of the lcd.
To the right of the lcd, there is also what i think looks like an inverter board underneath the main board. I have not found any...Leave a comment:

Re: Toshiba 55g300u. Picture goes on and off but sounds remains
tom66 there is a glow on the screen so it does not turn completely black as when you turn off the tv. when the picture goes off, there are like 3 spots that start from the top and turn into lines as they go down on the screen. sorry, a bit hard to explain.
aaron, i will open the back and check out the connections.
i appreciate the help!!!Leave a comment:

Toshiba 55g300u. Picture goes on and off but sounds remains
I just bought an used toshiba 55g300u. when i went to buy it there were no issues. i haven't really used it much, but it just started making a high pitch sound and the picture comes on and off in no particular sequence.
i have tried to use the different hdmi and cable inputs and it happens to all. the picture goes on and off but the sound remains. if i tap on the back cover the picture comes back or turns off. if you are on the menu and the picture goes off, you don't see the menu either.
i just need a general idea if the tv is toast, or if its an inverter, a bad... -

Re: Samsung LN52A550 Vertical Lines on 1/3 of Screen
yea i put the rubber like you had your foam. probably 1/4" high on all bonds. it wouldnt close cause the rubber was not as giving as the foam i guess. i cut it in half, put the metal frame and it was still giving me the lines.
i took them all out and started to push each one individually. the middle right is probably the culprit. i put the rubber and secured it with electrical tape and it works but i get a single line now that i can't get rid off.
i reseated the t-con again and pressed the other connections,...Leave a comment:

Re: Samsung LN52A550 Vertical Lines on 1/3 of Screen
ok i have it face up. i didnt have to unplug the wires. just put the frame to the side with wires attached. i have a rubber with adhesive that stands up to 176 degrees farenheit. it was the only thing i could find. i do have electrical tape that stands up to 220. should i just use the electrical tape instead of the rubber?Leave a comment:

Re: Samsung LN52A550 Vertical Lines on 1/3 of Screen
Hi again. I'm almost done removing the bezel but i'm stuck with these wires. they are connected to this board and i can't remove them.
Also, once i remove the bezel should i turn the tv over to work on the tab bonds and also be able to see the picture better?
Thanks again and again. lol...Leave a comment:

Re: Samsung LN52A550 Vertical Lines on 1/3 of Screen
Hello Debom3. Just a couple more questions before diving in.
I see that you placed the tv flat on the floor. Did you find its better to work flat rather than leave the tv with the stand and work on it standing up? I'm a bit worried about the back of the tv being open and laying the tv down were something might get crushed or shifted without the protection of the back cover.
Oh and can I buy those foam pads out of a regular hardware store like Lowes and or Home Depot?
Thanks again...Leave a comment:

Re: Samsung LN52A550 Vertical Lines on 1/3 of Screen
Hello there. This question is for Debom3. Unfortunately, I bought this tv through a craigslist ad. I went to check the tv and when I saw it, the picture was flawless. Needless to say, I got it home turn it on and after a few hours, the vertical lines started showing up.
I open the back, reaseted the t-cons and worked for a few minutes until the lines returned.
Being looking at your threads, and it seems that you were able to work out the solution without having to buy super expensive thermal pads like tom and budm....Leave a comment:
