Blue and red light flashes but no picture - JVC HD-61Z886 61" Rear Projection HDTV

my 37" xenius tv started losing its picture to a stripe screen then started flashing red blue green .know wont come on at all .wht part do i need to fix it please

Look to see when it tries to come on if it flashed bright red, green or blue. This set listed is prone to bad tubes and if acting up will come up and screen may flash--also if not coming on count the blinks on the red light--a specific number of blinks like 6 or 8 is a error code.

You have two problems: blue lines is convergence problem and the blue screen and shutdown is Blue Screen control is up too high.

generally when you get a constant green light all is ok. these different lights indicate different problems within the tv. so the pattern of lights you mention suggests there is a fault of some kind (is there a troubleshooting section in your manual)? either way it needs to be looked at.

I think your car kit has lost its pairing data. Blue and red lights flashing alternately means it is in pairing mode. On your phone (or the device it was paired with), delete the partnership with your car kit, and make it search for new devices again. After a little while, your car kit should appear on-screen. Select it and make it connect. If a pairing code (or PIN, or passkey, or passcode) is requested, enter '0000' (four zeros).
By the way, detailed instructions on how to pair it with your phone (illustrated with pictures) can be found on its user guide; In case yours happens to be missing, you'll still be able to find it here.
Hope you are able to sort your problems out soon.
Please, let me know if I can help you any further.

blue spot is probably light engine. Bad news. Flashing depends on the amount of times your timer power light blinks

THIS PROBLEM HAS HAPPEN TO ME WHEN MY LAMP WAS
ABOUT TO DIE. WHAT I DID WAS UNPLUG THE TV SET FOR
A SHORT WHILE, THEN WHEN PLUGGED AGAIN IT CAME ON BUT THE PICTURE WAS DIM AND THE LAMP ONLY
LAST FOR FEW DAYS AFTERWARDS.
