The light on my rca hd tv turns yellow after a few minutes but the tv doesn't turn on

Check or have a repair tech check connectors AP1 and AP2. Vibration rattles the power supply board (a crappy design, as the board is almost "floating") and causes the wires in the connectors to break, and may make intermittent contact. Heat may also cause intemittent contact. A very common flaw.

I had the same problem happen this afternoon, so I took it apart, and the source of the problem is the key controller panel (behind the buttons). It's held in place by 2 screws, if you take the case apart, which is literally only 15 or 20 screws, and then loosen the 2 screws holding the key controller panel on, and then use a small screwdriver to space it out from the button caps. Tighten the screws, and put it back together. Just be careful not to let it go too far to the other side, or you'll have a problem with the menu going on and off at random, which is just as annoying.

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

Actually the most likely not heat. At least heat is not likely what is causing the current issue your describing. The power supply in these and for that matter most AKAI televisions were very poorly manufactured. But the symptoms you are describing sound more like a common capacitor issue that the AKAI brand TV's are known for. Basically several of the capacitors on the secondary side of the board become bad and can bulge or leak and sometimes, they do not even show signs of going bad but still are not performing up to spec which is what causes the problem you are discribing. In some cases you may have other components tht have failed also but about 80-90% of the time it is due to bad capacitors around the board. There are several options online for repairing your power supply and some repair shops will work on them altough most will just want you to buy a new power supply. I repair LCD power supplies on the side and once repaired with better quality capacitors you should be able to get several more years out of your LCD.

You need to get the ballast repair kit #LSUC0002 and replace the parts to your ballast.

I have the exact same TV, did the above this past weekend, and the TV works like new.

You need to know how to solder though. It's not that hard.
