We were watching TV when we heard a loud pop and then the screen went dead (no picture, no light) but the sound was still on. I read my manual and it says that the lamp unit needs to be replaced after some time. I bought it in early 2007, so it is about 4 years working already. Before I go out to buy the lamp unit, I would like to know if that is really my problem or is there another possibility we need to explore. Also, if it is the lamp unit, where can I buy it? The manual says it is fair

Sharp lcd tv 42 inches, got wet by water, open inside: cleaned power supply, check fuse ok and replaced diode and triac. still not work, any helping idea from expert would be appriciated Thanks- Tom Atlanta
How much water entered the set? and was it just the power supply board that was affected? I will make the assumption that it was the case. In the majority of cases that involves water damage the only way to correct this, is change the power supply bo ...

I have an LG 42PC3D Plasma set. The set would not turn on so I did some trouble shooting and found and replaced all the capacitors on the power board. Some were bulging so I decided to change all of them. I also replaced the shorted IPM (the large chip under the heat sink) and related fuse on the YSUS board. I now have a working set again.
The problem I am having is the much typed about "red sparkles" on the left side of the screen when a dark background is present. I have read many posts abo

How do I find the power board in a 1997 big screen Sony TV to check the fuse? How do I check the fuse? I live in a house built in the 1890's, and last year there were 2 different tornados ,within 2 weeks of each other, that blew over trees on top of my power line twice in 1 month. My TV hasn't turned on since then. Is it the fuse I need to be checking? Should I replace the power cord, maybe just the cord is fried? It

My TV is showing convergence symptoms: the screen looks like 3D effects and as if someone is pusing in the middle of the screen.
I've replaced my STK's, 2 pico fuses on the G board, and tested each convergence resistor along with the pico fuses on the D board--albeit they were still soldered in place. I desoldered two pico fuses and one resistor to test them in said manner, but they checked out fine. I've gone over every square millimeter around the soldered area of each STK with a microsco
