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

Passmark Memtest shows multpile faults on test 11. Memory is itentified as 2 modules Samsung M471A5244CB0-CWE, which are available as standard so-dimm. Is it possible to desolder memory from such module and solder it on the MB? How to identyfiy which one on the MB is faulty?

by SpudgunHello 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...

by b-slayerHello.
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... -
by brispussPurchased 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),... -
by nrj1982Hello all,
I have a Lenovo Ideapad3 laptop, that has recently stopped working. When pressing the power button, the led is going on, but nothing else is happening.
I have checked the 3.3V, 5V and 20V - all of them seem present (checked with multimeter and oscilloscope in order to verify that they are stable).
I have checked the voltages around PU1901 - 0.9V, 1.8V, 5V, 2.5v, 0.6V and 1.2V - all of them are present.
Now going further in the debug, I found that the CPU voltages produced by RT3662AC (PU5901) PWM driver are missing. I can see that the 20V... - Loading...
