Re: Toshiba 32d1333b flashing red and green

I have this problem too on the same Toshiba TV model: Vestel power board 17IPS11 and logic board 17MB95S-1. Previously repeatedly cycling the power got it to work eventually, but not any more. All the capacitors look OK on the power supply but haven't had a chance to get my multimeter out yet. I'm suspecting a faulty logic board, which will probably cost more than a second hand replacement TV... Interested to hear if you ever found a different solution though!

Re: Technika LCD 32-270 - stuck in standby

Can report that a new logic board fixed it. Unfortunately the screen got cracked moving house so it's now a write-off, but good to have found the solution to the problem! Thanks all for your help.

Re: Technika LCD 32-270 - stuck in standby

Thanks for your message budm. Just tried triggering PS_ON myself with a resistor to 5VSB, then:

24V rail measures 23.4V
12V rail measures 11.8V
5V measures 4.8V
5VSB measures approx 5V

These look OK to me, so seems the problem is outside the PSU?

Re: Technika LCD 32-270 - stuck in standby

Changed C7 but ReeceyBurger was right - it didn't fix things. I'm wondering if it might be a logic board problem, given the corrupted video and sound beforehand, but power supply components are cheaper than buying a new board so worth ruling them out first! I guess I should be checking ICS1, ICS4 and Q5 (in pic 2) in terms of transistors?

Re: Technika LCD 32-270 - stuck in standby

Thanks guys - I've ordered a replacement for C7 - will let you know how I get on!

Hi there,

I've got a Technika LCD 32-270 (aka. M32/57G-GB-FTCU-UK), which is currently stuck in standby. When the power supply is on, it simply lights the red standby LED, and shows no sign of life when I press buttons on the side panel or remote control.

Directly before this happened, the TV picture was replaced by a bright green distorted mess and the sound by loud white noise - this lasted a few seconds before it turned itself off and went to standby. The same thing also happened a few months ago, after which I left it turned off for a number of weeks, and it miraculously...

Hello! I'm a physicist with a faulty LCD TV looking to repair it on the cheap. People on this forum seems very helpful, so thanks in advance for your assistance!
