Question about LG Televison & Video

1 Answer

Periodically, the tv screen goes dark gray and the "on/off" light stays green. When you turn it off, the green light flashes a few times before it goes off and turns red. When we try to turn it back on, the light flashes about 15 times and still goes to the dark gray screen. Sometimes it comes back on in a few minutes, but sometimes it takes days. When it does come back on, it works perfectly. We've bought 1 32" and about seven 21" LG flat panel tvs. We've had this problem with the 32" and one of the 21". We bought the 32" 3/06. We bought the 21" tvs in 9/07. We've given the 21" tvs as gifts, but kept one because of this problem. We really would appreciate some assistance. They're great tvs, but it seems with two of the eight we've bought having the same problem, we're probably not the only ones experiencing this problem. Thanks for your help!

LG has a serious problem with their soldering abilities. Since they started in the TV business their units have been less than stellar. I have seen enough of them to know that I would not buy an LG. In their defense, at the same time that they started making TVs the removal of solder from the process was mandated. This meant that they, as everyone else, would have to use more antimony which makes the bond harder and more prone to breakage. There you have it, the boards predictably broke solder joints and failed in various ways. In all my years of fixing TVs, when a unit works OK, then doesn't, then does, it is always solder joints. Now though, they cannot usually be repaired in the field. Look to the control board as this is generally where the problems originate. Let me know if you need more help. Thanks for using FixYa.

Here's the online manual for your TV:

http://www.tacp.toshiba.com/tacpassets-images/models/42HM95/docs/42HM95_om_e.pdf

Read the section about the red/green lights in front. It sounds like the lamp went out. Mine consistently goes out once every year to year and a half. If you plan on keeping the television, purchase two bulbs, so you have one on hand in case your new one goes out.

Good luck.

How many times Red Lamp flashes, its important as it shows problem and its location in tv. Below is detail of lamp blinks and you may know the problem area in tv by counting lamp flashes.
