SOURCE: fusible link keeps blowing out , shutting tv off

Arynsunn,

Thanks to you, I was able to find the solution to my problem.
Have you tried using the correct Fusible Link? I noticed in another post that you said you replaced it with a 500ma instead of the 400ma. I had the same original problem as you and found the exact fuseible links at www.mouser.com. Part# 576-3960400000 Littelfuse Fuses - A 125V UL TL LL .400A . They are only 55 cents plus shipping. I bought 5 for under $10 shipped. Only took 2 days to get them. My TV works like a charm now! I too thought I may need to replace the IC's but thankfully my TV is working fine. If you did need to replace them, where were they located? I couldn't find any stk IC's inside either and the IC's on the heat sinks are all small. Just trying to be proactive, in case I ever need to replace them.

SOURCE: blown fuse

Most likely there was a power event (surge, brownout, ect) that caused the power supply to fail in the TV causing the fuse to blow. you will need to have someone come and look at the unit and give you an estimate. If you keep putting fuses in and blowing them you could actually be causing more damage.

Reverse the AC plug from the set to the wall. Sometimes people will use a 3 prong adapter in which the hot/nuetral are reversed.

I have a 50" projection screen tv model #

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

I have a Mitsubishi VS-50604. The sound is working but the screen is blue. No picture. What is the problem?

andychen993,

Depending on how you have your unit hooked up you may have a switch in the wrong position or not have a signal to the TV. Blue screen is the option if no video signal is present. Is your audio going through an amplifier? If so check all the signal feeds to verify that you have a signal going to the TV.

The easiest way to check this would be to hook a DVD up directly to the TV using a separate audio and video cable. If you still have a blue screen I would go into the menus and see if the settings are correct for blue screen.

If everything checks out ok then you probably have a bad small signal board and will need to replace it.

I have a tip at http://www.fixya.com/support/r4425498-basic_standard_tv_troubleshooting which could be helpful to troubleshoot your unit. It explains how to troubleshoot a dead TV but the procedure is the same to isolate a defective board.

Thanks for using FixYa and for the generous rating. We supply these answers for free.
