Television and Home Theater

my 5 yr old Magnavox rear projection died on me last week. No audio or video with an intermittent chirping coming every 1 to 1.5 seconds. I have already purchased a new Lcd but began tinkering with this tv for a possible garage television. I checked all resistors around the convergence chips and they all tested good. I replaced the ics with sanyo oem 392-120 and have good continuity from chips leads throughout tracers. I put back together and same thing dead tv other than chirping. Any ideas?

I have the samsung hcl4715w television. The picture is fuzzy and there are red lines across the top of the screen. If anyone has had this issue and found a resolution it would be good to know. Thx

Its a crt rear projection mod# kp57ws520.My wife let a feral cat into the house over the weekend as she felt bad for it in the 4' of snow.it promptly went behind the tv and peed right into the back of it.while it was on,it immediatly shut down.now no picture looking around on this forum I see the blinking has a meaning.upon turning on the tv 4 red blinks,no picture then shuts right off.I read the article not sure what to do with that info.Is there a hope that this is repairable for less than a new tv?
