Re: Toshiba LED TV, blank screen

Hard to resell led tvs around my area too, argos the minute are doing 32in hd ready proscan sets £139.00 so trying to sell any repaired sets for a resonable mark up is hard imo at the minute.

There is still no remedy, for this problem?
There is a TV on CL and I'm not sure, if I should pick it up or not.

If you're not prepared to take the risk then you should probably avoid it. LED TVs are proving real hard to fix due to LED array failures and LCD panel faults. I've also found that, at least around where I live, they don't command that much of a premium over conventional LCD TVs, so they're not worth much to me either.

For future reference, it is much better if you cut the flexible wire on the plug rather than the pin on the socket - wires are much easier to join back together again.

In this case you will need to get a whole new socket if you wished to rejoin them.

Re: Toshiba LED TV, blank screen

Well I cut the lead that goes to pin 15, and the problem is still there. Any assistance would be GReAT

Can you please report the DCV Voltage readings of all the pins?
BTW, if the BL-ON (pin 16) is not present, removing pin 15 (dim) is not going to make backlights come on.

Re: Toshiba LED TV, blank screen

Can anyone confirm if firmware fixes this issue? Do you have to first pull or cut a wire to get it to stay on to do the firmware?

Re: Toshiba LED TV, blank screen

Hey guys found this post and thought I just insert my experience.

I like others have tried all the fixes listed above, pulling the #15 pin and then switching #15 and #16, DID NOT WORK! (for me anyway)

so I pinned all the wires back to there proper places and was gonna call it a night. Before all that I tried powering the TV on one more time. Saw the Toshiba logo and then darkness. The back panel was still off at this point, so I pulled the wires from P803 just to see what would happen..... nothing happened...... and with out thinking I plugged the wired into the P804 port and noticed light coming out of the screw holes from behind the TV to my surprise the unit was on!!!

I powered it off and tried to start it up again and it crapped out on the red logo and went dark.... so while it still had power I snatched the wires from P804 and plugged them into P803 and the screen came on again.

Im gonna try the firmware update and hopefully that will make this stick.
Now before you techs rip me a new one im well aware of what potential damage I could be doing to my TV but since its already pretty much Dead to me at this point im willing to experiment.

with that said !!!!!PERFORM AT OWN RISK!!!!!

spend a little money and fix it the right way Mine was garbage up until about 30 minutes ago

Re: Toshiba LED TV, blank screen

Did you get it eventually fixed? I'm having the same issue. I've tried to PM you, but it won't let me.

I think you need a few posts before you can PM people

Re: Toshiba LED TV, blank screen

I received a Toshiba 46L5200U on Friday where the Red Logo would appear for 2-3secs then the screen would go black. I cut the yellow wire, and bam it fired right up. After letting it play for 24hrs continuously, I powered it off and tried to power it back on. It would flash the logo and go blank again. I went to

https://web1.toshiba.ca/support/ceg/...?docid=D000050

and downloaded the newest firmware for the set, and installed it. It seemed to fixed the blank screen problem, and enhanced the picture quality tremendously! If all else fails give this a try!

Re: Toshiba LED TV, blank screen

Having similar problems with my Toshiba: 32C120U. Problem -- TV comes up and shows the red Toshiba logo every time, then you see a slight flicker and everything goes black. Have had some success getting it to turn on every now and then by a combination of unplugging and plugging it back in several times. Seems that once it does work it works. Have tried a number of the ideas in this thread but nothing has worked.

Not sure if this is what you are needing. My TV is reassembled and working great, so I don't want to mess with it anymore. This image was from one of MDluffy's original posts and I simply copied it and added some highlights to show which pin I clipped.

Thank you, so much. I pulled that wire and taped it off with no results. I believe its time let this TV go now. I'm glad you were able to get your TV working again.

Re: Toshiba LED TV, blank screen

I have been following this thread for a few months now and have tried switching wires #15 & 16. I've also tried pulling and taping off wire #15 at the PSB. Is it possible for a picture of the connection to the board to be taken? If not, that's understandable, I'm just extremely close to just giving my 2 year old TV away.

I've purchased and replaced the backlight inverter already, this is so frustrating. Yes, I've been a lurker, sorry. Thank you to each and every one of your responses to this common issue.

Re: Toshiba LED TV, blank screen

Using the information in Post #32 as well as Post #35, I was able to pull the #15 pin out of the connector housing on the PSB and clip it off. I left enough length to insert it back into the connector housing, but not long enough to reach the female connector when attached. The tv is now working brilliantly.
