Question about LG 32LG30 32 in. LCD HDTV

Open Question

I have an LG Jazz 32" Full HD LCD TV. The problem is that the TV does not switch on(no red LED light) and the screen remains blank. Give it a rest of a day or two, then it powers on and works alright for a five to six hours and switches off again automatically. Also it takes a lot of time for the red light to come on once the power supply is plugged in and also for the blue light when TV is switched on through the remote. This has been going on for two weeks now and Iam at my wits end. Can somebody help?

Bad caps in the power supply. Replace all bad cap or replace Power Supply Module. If you choose to try and fix it yourself yourself will need a ESR Meter to check the caps in circuit. Let me know if this helps.

There is probably a bad capacitor on the power board, I had the same thing happen to my 42LB1DR after 2 years. T.V. would turn on and white power light would blink, no pictue and no sound. If your'e a diy'er, it is not that hard of a fix. Take all the covers off of the back of the tv(UNPLUGGED!!!), then look at all the capacitors on the power board. lcd_repair_4_bad_capacitors_lg.jpg
These are the capacitors, look to see if any of them appear to have a bump on the top of them. They are supposed to be flat, you can also tell if one of them has gone bad if there is an oily substance on the metal cover that was removed. If one of them is in question, carefully remove the board, and take it to an electronics store to have them sotter ?sp on a new capacitor. It ended up costing me around $40.00 to have this done. Good luck and if you are not comfortable trying this, than take it to a repair shop, but I was quoted around $450 to take the T.V. in. No Thanks

Whe you press the power button the TV led have to blink several times and the it have to change to blue, meaning Tv is on.
If you press the power button and the led start blinking and goes off, then you need to replace the mainboard because it is damaged.

Bye

Hello, I need more information to focus on the problem. When a malfunction occurs, whether you get any indication on the screen while pressing the menu button on the remote control. Is the voice remains in issue. What happens with the waiting lights.

Problem for choosing lcd tv


Hello,

When you buy a samsung, you buy a LED TV with a panel manufactured
by the company "S - LCD" which belongs to 50/50 % sony and samsung.
The S - LCD company is fully driven under samsung engineering.
Today, sony seems to buy their panels from "sharp corp" and trying to
seperate from samsung due to the cold war (high competition ) between
them

Just go for the samsung UN32C6500 32" 1080p LED HDTV.

Theres no better picture quality you can buy for 32".

Good luck....

Stuck in standby.


Mainboard damaged and need to be replaced, try EBAY for a general picture of prices but you will need your product code wich is located in the back of the TV next to serial number.
