When turned on the screen flickers with different colors and after 10 seconds shuts off.
What problem is the likely and what would it cost to repair?

Unlikely to be economical - I do not know how it is in the US but I regularly see 32 ~ 34" Sony Trinitron 1080i HDTV CRTs (XBR) given away for free - must be a couple every month...
I would, with my little CRT knowledge, suggest high EHT causing xray detect fault (safety engaging.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Check the elec. capacitor off the horz. drive transformer, its a low value (1-2uf) around 50v. also could be shorted diodes/output transistors in the vert. output circuit.
My wayback machine is't working too good right now.Comment

Sounds like the 2005 RCA CRT that I posted about a while ago.
Heard that it can be a bad solder joint and for the above mentioned CRT TV, it would shut off by itself after roughly 10 seconds, if I try to use it after it was turned off. (Seems that it has to warm up before it even possibly stays on.)
That guy is long gone now! It was kicked out of the house then left in the snow, ice and rain before someone hauled it away.Last edited by RJARRRPCGP; 02-03-2014, 09:34 PM.ASRock B550 PG Velocita

If I was repairing it in the shop it would be around $100.00 plus parts plus tax.
even though its an old tv it still takes up time to repair.Comment

try R_J advice. also caps near vertical ic that has range same as he said and 50v. it look like your tv gone to protect mode because something wrong. many times just a failed caps about 50v. but who knows yours.. sometime there's another factor too."There is no shortcut to be successful.

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Greetings,
I have an iPad Pro 12.9" 6th gen tablet that had a screen replaced about 10 months ago at a repair shop and last week the screen went blank during use. The device was still on, notifications played sound for example. I have replaced the screen twice, both screens are working until I unplug it, at which point I can see that screen is on but is all black. If I press the power button, the backlight goes off, and when I press it again, the image appears for half a second and then the screen goes back to being black but on. This issue is not present at all when the iPad...10-24-2024, 11:55 AM -
Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
