Re: HELP Please with faulty TV
Sorry, forgot entirely about this post.
Red hue slowly fading is T-con or panel, or perhaps the supply voltage to the T-con.
When the hue appears have you tried pressing the bonds? On the IC as well as the bond->LCD and board->bond areas?
Also, try slowly and carefully heating them with a hairdryer to see if you can get the effect to occur quicker.Leave a comment:

Re: HELP Please with faulty TV
Ok, so I tried looking at the tabs and no help.
I thought that if I uploaded a video for you that might help?

Re: HELP Please with faulty TV
The tab bonds are on the edges of the LCD panel itself. The operation is difficult but typically achieves over 90% success rate.
Different faults, but same base cause:

Re: HELP Please with faulty TV
Ah yes "K" my bad. Its not actually my TV but said I would fix it, thinking that if I replaced all the boards as I have done with others that would sort it. But no joy
How would I fix these "tab bonds" and where are they situated?
Thankyou for your time too, really appreciate it.

Re: HELP Please with faulty TV
There should be an additional letter before "V".
Looking at the menus I'd say you've got a Vestel built Toshiba (if that letter is a "B", "D", "S" or "K"), which is the same as a Bush or Alba or any other supermarket cheapie. (You would be right to be disappointed if this is the case.)
A lot of bad panels on these models, due to tab bonds. It is usually fixable though.Last edited by tom66; 02-24-2013, 05:02 PM.Leave a comment:

HELP Please with faulty TV
Hi,
I wonder if you can help I have a Toshiba 32V500B. After a while of being on 1 min or so, a red hue appears on the screen and gradually gets worse.
So far I have changed the inverter, power board and output boards.
What else could it be?
I will attach 2 pictures to show you before and after 1 minute of being on.
regards
Berts

Hello esteemed members. I appreciate that my question will strike some as being somewhat childishly simple, but it genuine perplexes me! I have repaired several laptops before by removing a faulty capacitor that was short-circuiting the motherboard, whereupon the laptop would then work. For me, it begs the question that, if the current can bypass where the capcitor was when it has been removed, why didn't it just bypass it when it was present and faulty,? I can't get my head round the premise that if the other side of the capacitor is connected to ground, then why doesn't the current simply bypass... -
Hello.
I have an Acer Aspire A317-53 laptop with faulty onboard ram modules, after online searches, I have only found two options to get it working :
- first one is to modify le bios to disable the onboard ram.
- second one is to disable the onboard ram by desoldering some components on the mainboard.
so after some hours google-ing, i have to give-up the modified bios option, main reason is I couldn't find anywhere a such modified Bios, alternate reason is that if windows update makes a bios update, the problem is always here...
so i found that my motherboard... -
Purchased a Ryobi 36V 6Ah battery pack maybe just over a year ago.
Battery pack had been used on about 3 or 4 occasions for powering a cordless lawnmower. I was wanting to use this battery pack again recently, but on checking the battery charge state via the battery pack test button, there was no LED indication at all of charge state which suggested the pack was fully discharged.
I found this to be odd as I usually fully recharge battery packs shortly after use. So either the pack developed some sort of fault which completely discharged the pack cells (after recharging),... -
Hello everyone,
I've been encountering some perplexing issues with my ASUS ROG STRIX GTX 1660 Ti Gaming OC and am seeking insights or potential solutions from the community.
Symptoms:
Initially experienced a gradient-style black screen from the top.
Poor performance: ~10 FPS on the lock screen.
Encountered artifacts followed by black screens.
After addressing a PSU-related problem, still observed a performance drop (~10 FPS).
Upon using GPU-Z:
Memory size shows as 0MB.
Unknown bus width and bandwidth reported.... -
I have a Tekram P6PRO-A5 Rev. 1.01 which has an issue with one of the memory slots and with the floppy port.
When a memory module is installed into the slot which is closest to the north bridge, the board will beep and won't post. The same memory module works in the two remaining slots.
Also, the floppy drive does not work regardless of bios settings.
Please help me to identify the possible cause of the faulty memory slot and the floppy drive port as well.
I have examined the board under my digital microscope and did not find any broken traces....
