Mitsubishi rear projection tv not getting high voltage to CRT guns

I have a Mitsubishi rear projection 65" tv. The back panel was off the tv and my cat got behind the tv. After she jumped out, the tv shut off. when I tried to turn it back on, there is no picture, but only sound. The guns in the back of the tv are not turned on at all, so I am assuming it may be a high voltage problem, but I am not sure, and I dont know how I would go about testing or fixing it. Please help, I do not want to part with this large tv.

My TV won't power on. Green light comes on, then off/ Error code 21


error code 2 1 is from the x ray protect or high voltage circuit. there are many individual components that can fail and cause that shutdown.
to repair you would need to be experienced at troubleshooting electronics and would probably also need a schematic diagram. or have a shop repair for you.

Have a Sony KP-65WV600, already replaced d board once, and replaced convergence ic's once also. Now as soon as I turn unit on, turns to red screen and shuts off, video that is, audio works ok, noticed...


Check High voltage Block.After replacing ic's (STK convergence ic's) you need to adjust Black&White scale.Turn ALL screen adjustments to min.Turn TV on and adjust screen slowly for each gun (I would start with Red first ) when you came to point that you see red background with white lines across, at that point G2 is too high (that will cause TV to shut down,don't worry just lowered adjustment and turn tv back on) so adjust to proper voltage and do the same for each gun.After that, adjust focus for each gun (again all controls are on High Voltage Block and HVB is mounted on front of your tv after you take speaker gril out) black box with 6 controls' screen RGB, focus RGB .
You should do that in dark room in order to get perfect Black&White scale,when all guns are adjusted properly you will see grey picture.Make sure 'Color" adjustment on your display is down to 0. Another step is convergence adjustment ,Flash Focus etc.If TV stil shuts off after all, your Red picture tube is short inside,take crt pcb from tube,make sure TV is unpluged from power before that, and turn Tv on .If stays On tube need replacment...good luck)

Mitsubishi WS-65513 65' The red keeps going out


It could be a loose component video cable, check your TV menu or another device when it goes out. If you have red in the menu or other device, it cannot be your CRT. The Crt is somewhat hard to replace but if everything goes great it isn't too bad. I usually mark all the yokes and magnets with a marker so I can put them right back in the same place and the picture should be about the same. Sometimes you need to do a lot of adjustment and that is when it can get tricky, kind of depends on how "identical" the new CRT is to your old one.

Let me know how I can help

No picture, high voltage cable sparks at left tube/gun at turn on


It sounds like you have a shorted picture tube.
You should call a good TV Tech to confirm this and get an estimate.

Red convergence problem - Mitsubishi 65


It sounds like your red gun might be close to going, we had the same problem our tv. The red was off and couldnt really be adjusted but the others were alright. We were told that the red gun was nearing the end of its life and it could cost upwards of $1000 to fix, so we just got a new tv. i would suggest having a tv tech come out and look just to make sure, but thats wut it sounds like.

No Green CRT projection


check the high voltage supply. each gun have a single input. be very careful, high voltage (1000v).
you are looking to buy a high voltage transformer. it is not cheap, and it is not easy to find.

MITSUBISHI 65" WIDESCREEN MODEL WS 65809 (GREEN GONE, SMALL RED LINES)


in the front cover turn up screens on all colors till you see retrace lines, then back them down to where dissappear. enless you know the correct voltage to set it. as for the green. i would try the red crt on the green and see if it looks ok. if so then replace crt circuit or check transistors on crt circuit may also need to change the driver on the heat sync.

Color changes


Your tv has three crt guns that correspond to how it makes colors.

If its just one color acting weird it might be the crt gun for red. That sucks cause it will be hard to replace. I think its possible to fix it but it might not be worth it... Sorry...
