What can I do?

⟐ Answered September 06, 2020 at 0:31 MST

• Intermittent white vertical lines flashing/flickering, especially during scene changes.
• Picture corruption only; audio remains normal.
• Issue occurs with regular daily use and resolves temporarily if the TV is left unused for one to two weeks

Troubleshooting already attempted:

• Factory reset.
• Power cycling (short and extended).
• Software update.
• Tested with a single input source (DVD player).

Based on the symptoms, I suspect a failing T-Con board, but it may be something else. Looking to find out what I need to source and where to source it.

The strange thing is that once the TV is on, the remote works fine. You can change the channels with it and volume and so on. You can even turn the tv set off with the remote. But once off you cannot turn it back on with the remote.

I thought that maybe the remote was the issue. But before going out and buying one I downloaded a remote control App on my old samsung phone that has IR capabilities. So i set the app to work for the Seiki TV and it also wont turn the TV on. But again once I turn on the TV using the power button on it. I am able to change the channels volume and even turn it off using the app on my phone.

Does anyone know if it may be the IR sensor on the TV itself that can be causing the problem or can it be something else? The TV has no issues once on. I have used it fora few hours and haven't seen anything else wrong with it.

This is the IR sensor it has.

The diode thing looks to be melted. No writing visible on it.

This is picture of the logic board for reference.

Hello,

I have a Daewoo tv, model DPP-32F1, after plugging in the power the standby light starts blinking without stopping and the tv doesnt start. I opened the back cover to check the boards. After some testing I saw that the AC-Det is 4.1V instead of 5V. Is that a possible problem and how to fix the tv? Also there are no blown capacitors or visible damage.

Like in the title, I changed the backlight for the tv, now it only flashes Red, green, Blue, Black, white. Ive tried power cycling it but to no avail.
