You can try contacting LG for a replacement picture board for your tv set since they most likely have the part for it

The tv is at least 17 years old.The blinking red light blinks 5 times ,then the tv picture goes off . The voice is still on


Five blinks is the error code for an AKB (auto kine bias) error. What this means is that the set isn't able to balance the three color guns (red, green and blue) of the picture tube properly, and it's blanking out the screen.

To get the proper colors, the signals for the three colors need to be balanced, and Sony sets have circuitry to do this automatically. Other brands don't, and when they go out of balance you see a picture that starts to show tinting or colors that are off. As the picture tube ages, it gets harder to adjust the balance until finally the AKB circuit can't anymore, and poof, the picture goes away. With a 17-year-old tube, it's not surprising.

There isn't anything that can be done to fix the picture tube, it would need to be replaced. But the cost of the tube and the work required to get it set up after installation makes it completely uneconomical to repair this TV. A new picture tube is nearly $200. Then special tools are required to set the tube up (a process called convergence), so you'd need to find someone to put it in, and possibly pay to have the old one disposed of. A new 32-inch LCD set is around $350 now. Treat yourself to a new one.

I have a 5 yr old akai flat screen and the picture and sound are gone???The sound was the last to go.


First need the size tv 19",27" ect. and model number of this set but I believe if it is the LCD it has a simulator power supply as the LCT32HA36 and can be repaired easily by replacing capacitors also.

No Picture on a 4 yr old TV


I would take it to a repair shop, but it sounds like somewhere in the power board.

Sony Trinitron TV now taking around 5 minutes for picture to appear (sound comes on instantly) Is it worth repair or should I cut losses and replace set?


How old is the TV?
Sony Trinitron sounds like it may be from the 1980's?
Some TV engineers can use a piece of equipment to do a "tube boost" but this is sometimes risky and can completely ruin the tube, but it's a risk you would have to take.
If the TV is over 15 years old, and has been used regularly, (like 4 hours every day or more) it seems likely that the tube has reached the end of life.
TV cathode ray tubes are like light bulbs...they do not last forever!

1/2 picture on my vizio 42" TV


Are you under warranty? Chances are real good that you need the signal board....the one with the rca jacks and rf connectors. This may be pricey $$$$$ but will surely repair the problem.

12 yr. old 25" G.E. picture fading


I gotta love it when people make up answers. There is no such thing as a "contrass module". I'm assuming the poster meant "contrast". The trouble is your 12-year-old picture tube. It's gotten weak and isn't getting as bright or sharp as it used to. Picture tube manufacturers estimate the useful life of a tube at about 7 years today. There are adjustments inside that might help some, but you need a new picture tube. It's going to cost a lot more than $60 to $75 for that. You're better off replacing the TV.

16 yr old 25" Zenith..1st colors went yellow/lime now TV is dead


Absolutely not worth repair. You have described a classic symptom of Zenith picture tube failure, and about 99% of the time the main board in the TV is ruined as well. You've gotten good life from the set (manufacturers figure tube life is around 7 years these days), so it's time to replace it.

17 yr. old 35" RCA loses color intermittently. Picture & sound ok


Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.
