My tv 32ld550 use to take awhile before it comes on now it dont show no picture r sound the red power light just blinks

SOURCE: power light blinks red - tv will not come on

I bought one of these tv's at a thrift store and it had the same problem, orange light blinking and static sound coming out of the speakers, no video at all.
The problem was the power supply board, this power supply has multiple outputs that feed the circuitry, 12V, 24v, 5V.
There was nine electrolitic capacitors I had to replace to fix it, all of them were bulged they are easy to spot, I measure one of them that was supposed to measure 1000uF but measured only 65uF. you can buy these from digikey for about 50 cents each, they need to be rated at 105 deg c and the profile has to be below the heat sink otherwise they will hit the top of the heat sink, the spacing between the leads has to be 5mm so they fit in the pcb. I replaced 3 1000uF/25v, 3 470uF/16v and 3 1000uF/16v and that fixed the problem, I bought this tv broken for 100 bucks fixed it with 6 bucks.
Good luck, don't perform repair if you are not familiar with dangerous AC voltage inside the TV.

SOURCE: tv turns on but no picture just a red blinking light stays on

Red light blinking means there's a problem in the TV....

What kind of tv is it?

SOURCE: TV won't come on - get a blinking red light instead

Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you the flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
