Hello, I have a Toshiba 57H84R rear projection tv that has developed a problem. Occasionally the screen would turn bright blue for a couple of seconds and then go blank (dark screen, like it had shut off). The red power button would go from a steady red light to blinking continuously and would have to be unplugged, then plugged back in to get it to come on again. One time it did this, there was a bright blue circle in the center of the screen and now there is a permanent yellow spot in the cente

Main Board? Had issues for years, where I had to unplug once in order to get the tv to turn on. Then one day, it would not turn on. The TV shows a quick lightening of the screen like it is going to turn on, but nothing appears. It also clicks once or twice. Took to a repair shop and they diagnosed with main board failure and refused to fix due to lack of parts. Do you think it is the main board and where would I find one? I am pretty handy, do you think I could DIYthis job?
The fault must be due to a main board fault. Generally, it will be impossible to get this board repaired. A replacement must be done. Most of the parts in this board are not available by local electronic spare part market. After power ON, there sh ...

Samsung tv's The picture started going cloudy and grey so we turned the tv off for half an hour .When we turned it back on it was ok for 20 minutes and then it went grey and cloudy again.
You could still make out the programme images behind the cloudy screen but when we turned off and on the cloudyness happened quicker.
I was told by my local tv shop that the repair and part needed to fix the problem would be around 400 pounds and that it would make more sense to buy a new set.What is your opi

I saw a video that said when it does that it could be the power supply or the main av board, what do you think?

CC was always on and working fine then yesterday everything worked fine on our Sony Wega Trinton 27" square TV and all of a sudden it does not work on any channel. We go through a box with our cable co. Comcast and they said its not them. Everything is checked off right and turned on.
So what could have happened? Can you tell us whatt it is and how to fix it?
I recommend turning on the cc "on" in the cable box and see if that helps you out. Let me know if that works for you... Good luck... HDTV GURU JAY. ...

I have a ten year old 37" Sony XBR TV that works fine until you turn it off and then go to turn it back on. The picture does not come back, but sound does.

The picture will come on when you first turn it on but after 15 minutes or so it fades away. The sound still comes out but no picture. Sometimes it will come back on on its own after a while and then go out again. If you turn it back off for 15 minutes or so it usually comes back on. We already bought a new tv and that one works fine so its not the cable box but I would like to put the old tv in my room.

My kdl55nx810 screen is blinking. While watching TV, the screen will go black for about 2 seconds, then come back on. It appears to happen intermittenly, every 15, 30, or 60 seconds. TV was working fine, when I went into the menu and adjusted the motionflow. I ended up returning TV to the original setting. When I started watching TV (after returning to original setting), the problem started. The TV does not turn off, but the screen goes black temporarily.
Any help would be appreciated, thank

This new board also has a place for a plug the old one dont. could this be why it will not turn on? And yes i can put the old board back in and it will come

I have a Samsung LN-s2651d LCD tv that black screened on me and I don't know if the sound works because I have the internal speakers turned off... I use 5.1. I have been told that it is the t-con board and would like to know if there was any way to determine this with some certainty before I go buy the part. Or, could it be something else besides the t-con board?

I have a 9 yr old D52W20 RCA tv. It turns on and is fine for about 35 minutes. Then it turns off and then right back on again. it takes about 15 seconds from the time it turns off for the picture to reappear. It will stay on anywhere from 5 to 30 seconds before turning off and back on again. I had a repairman come in and he said it was not the capacitors but said he needed more information. At that time the unit would be fine for a couple of hours before it would start acting up. Any thoughts

Hi, my 32' Vizio won't turn on and the orange idle light does not come on either. Before this happened I would have to turn it on 3 - 7 times before it stayed, meaning I would turn it on then it would turn off etc. When it was on though it stayed fine. I know I can't fix this myself but how much would a typical repair cost?

We own a Sony FWD-50PX2 television. A few weeks ago it would not turn on. The power is going to the television. When you try to turn the tv on you can hear it pop and the red light showing it is off will flip to green and then turn back to red. We would like to just repair the TV as it is a very nice television set. We thought possible power supply, but it is trying to turn on. Any help you can give to help correct the problem would be great.

I have a Samsung HLP 4674w DLP. The picture started to lose color and look like a negative image. Then it would get scrambled and eventually go out. Powering on and off sometimes fixed it, but only temporarily. Sometimes it would also turn off and on by itself. I thought it may be the lamp so I replaced it, but it did not fix the problem. Next I thought it may be the color wheel so I replaced that, but the problem did not go away. Also when this happens the Power switch will not turn the TV off.
You need to change the lamp out, it builds up a internal resistance, and pulls your voltaged down, it will get to the point where you TV will not come on at all. Replace your lamp, you can get one at ...
